This is an overview of the regular, recurring, and other characters of the CBS TV crime drama series Blue Bloods.
Commissioner Francis Xavier Reagan, portrayed by former Magnum, P.I. star Tom Selleck, is the patriarch of the Reagan family.
Frank is the younger son of Henry (Len Cariou) and Betty Reagan, born in Bay Ridge, Brooklyn, New York in the early 1950s. His older brother, Peter Christopher Reagan, died of leukemia at the age of 18 months, over a year before Frank was born. Frank married Mary Margaret Reagan (née Conor) in the early 1970s, and they had four children together: Danny, Erin, Joe, and Jamie. Frank is also a loving grandfather to Erin's daughter, Nicky Reagan-Boyle (Sami Gayle), and Danny's two children, Jack (Tony Terraciano) and Sean Reagan (Andrew Terraciano). It's revealed in Season 10's "Family Secrets" that Frank also has one more grandson, Joseph Hill, the son of Paula Hill, whom Joe Reagan met at the academy. Paula said the two had a brief affair and she never told Joe about her pregnancy or his son. Paula visits Frank and reveals the news in an effort to get her son, a young detective in the firearms unit, assigned to a less dangerous precinct.
After serving in the United States Marine Corps during the Vietnam War (during which time he held the rank of Lieutenant and was awarded the Navy & Marine Corps Achievement Medal), Frank became the third generation of Reagans to become a police officer. He began his career as a patrol officer, and was later promoted to Detective 3rd Grade. He thereafter served in various positions across the city, including Chief of the Brooklyn South Division and the Chief of Department of the NYPD, culminating in being appointed Police Commissioner.
On September 11, 2001, Frank was working in the North Tower when the South Tower collapsed. He spent days at Ground Zero, and took refuge at St. Paul's Chapel, where he and other officers slept in the pews. Frank was appointed the Police Commissioner by Mayor Frank Russo (Bruce Altman). In 2011, after the election of Carter Poole (David Ramsey), Frank offers to tender his resignation, but Poole decided to keep Frank on as PC. In the first season, Frank is well regarded and respected by his officers and his city, to the point where the mayor felt threatened by his popularity; however, by season 6, public opinion regarding the police – and him personally – has changed so drastically that he gets booed off-stage while speaking at Columbia University. However, in season 7, new mayor Margaret Dutton affirms that his polls are better than any of the NY Mayors.
Detective First Grade Daniel Fitzgerald Reagan is the eldest son of Commissioner Frank Reagan. He is portrayed by New Kids on the Block singer Donnie Wahlberg.
On the job for 15 years (as of season 1), Danny took a leave of absence from the New York City Police Department to serve two tours in the Iraq War as a Marine. (He had enlisted and served in the Marines shortly after high school and prior to joining the NYPD, and either stayed in the Marine Corps Reserve and was activated, or volunteered to reenlist at the start of the war.) Danny saw combat in Fallujah, and was the only member of his platoon to come home alive (resulting in some post-traumatic stress). During his time in the Marines, Danny was decorated for heroism.
He is old-school; his hotheadedness and harsh methods of detective work sometimes get him in trouble, which his father worries about. When asked if his son "crosses the line" and violates procedure from time to time, Frank answered, "I think he walks on the line". Danny is hard on other policemen and detectives when he feels they are unprofessional or not doing their duty to its utmost. He is currently assigned to the Detective Squad of the 54th Precinct, and partnered with Detective Maria Baez. In "Most Wanted", it is mentioned that he leads the Manhattan South Detective Borough in both collars and complaints. In "Love Stories", he and Baez are awarded the NYPD Medal for Valor for their actions in "Partners".
As a detective with the NYPD, Danny carries a Kahr K9 in 9×19mm as his duty weapon, and drives a Dodge Charger on duty, which replaced his previous Chevrolet Impala 9C1. He also owns a Glock 19 in 9×19mm, and previously used a Smith & Wesson 5946 in 9×19mm. Danny drove a Jeep XJ Cherokee as his personal/family vehicle from Season 1 to Season 5, whilst Linda drove a rather troublesome 2001 Kia Sedona/Carnival; this vehicle was replaced when Henry lost his driver's license and gave Linda his car. In Season 6, Danny's Cherokee was replaced by a fourth-generation Ford Explorer.
Assistant District Attorney Erin Reagan is Frank Reagan's only daughter. She is portrayed by Bridget Moynahan.
A New York County Assistant District Attorney and single mother, Erin is the second child and only daughter of the current New York City Police Commissioner Frank Reagan and his wife Mary. She grew up in Bay Ridge, Brooklyn, with three brothers, Danny, Joe, and Jamie. It is implied throughout the series that she had something of a wild streak growing up (unlike her daughter). In season 5, it is mentioned that she graduated top of her class from Columbia University. She later went on to attend Fordham University School of Law. In season 6, Erin celebrated her 40th birthday.
Erin is divorced from John "Jack" Boyle (Peter Hermann), a criminal defense attorney, whom she met when they were 19. Daughter Nicky is the couple's only child. In "Old Wounds", she finally changes her name from Erin Reagan-Boyle back to Erin Reagan. Since her divorce, Erin has had a few romantic interests. She and her boss, District Attorney Charles Rosselini (Bobby Cannavale), flirted with each other and even shared a kiss after a date, but nothing ever came of it mainly due to Erin's reluctance with the idea of dating her boss. In 2011, she met Jacob Krystal (Fred Weller) at an art gallery; she later learned that he was an art thief who returned once-stolen works to their rightful owners, and he left town. In 2013, after being shot in a courtroom hostage situation, she began dating her ex-husband Jack, but eventually broke up with him when she realized Jack only wanted to date and that he didn't want a serious commitment. In 2014, Erin met Robert McCoy, a defense attorney, on a speed-date, and the two became romantically involved until he was appointed interim District Attorney, at which point she said she can't sleep with her boss.
Erin is almost raped and killed in "Re-Do", though Frank saves her life by shooting her attacker dead. In "To Protect and Serve", Erin is taken hostage and shot in the arm at the courthouse. She is saved by Danny after he says a coded message, "Please, don't hurt my family," after which she dropped to the ground, and Danny shot her assailant. It is revealed that their father taught them this when they were young, as a plan in case one of them was ever held at gunpoint.
In "Working Girls", Erin is offered the position of Deputy Mayor of Operations by Mayor Poole, but she turns him down. In "Ends and Means", Erin is promoted from Senior Counsel to Deputy Bureau Chief of the Trial Bureau. In the season four finale, she filed a complaint against her boss, Bureau Chief Amanda Harris, upon learning she had abused her power. In season six, Erin was considered for a judgeship. Erin is on the short list to become District Attorney in the season 11 episode "In the Name of the Father", after her boss, DA Samar Chatwell, is arrested on corruption charges. While Erin is on the short list to be named Acting DA by the governor, the governor ultimately chooses the then-Acting DA for Fulton County, Georgia (Atlanta) for the job.
Like the rest of her family, Erin is licensed to carry a firearm. Her weapon of choice is the Glock 19 in 9×19mm, and according to Frank, she's a better shot than Danny and Jamie. In season 8, it was revealed Erin wanted to join the police force like her family, wanted to take the exam but it wasn't for her and chose law and became a prosecutor.
Sergeant Jameson Reagan is the youngest son of Frank Reagan. He is portrayed by Will Estes.
First introduced as a young police officer and recent Harvard Law School graduate, Jamie is the youngest child of the current New York City Police Commissioner Frank Reagan and his wife Mary. Jamie grew up in Bay Ridge, Brooklyn with two older brothers, Danny and Joe, and an older sister, Erin. His shield number as a patrol officer was 60528, and as a sergeant is 71181.
Henry "Pop" Reagan is a former New York City Police Commissioner and the father of current Commissioner Frank Reagan. He is portrayed by Len Cariou. He is described in one source as "grizzled family patriarch Henry Reagan, a retired NYPD police commissioner who saw military action in World War II and Korea".
The retired New York City Police Commissioner and father of Frank (grandfather of Danny, Erin, Jamie, and the late Joe; great-grandfather of Nicky, Jack, Sean, and Joe Hill). In the season 13 episode, "Homefront", broadcast in 2022, Frank states that Henry is 88 years old, which would place his year of birth around 1934. Henry's childhood was hard due to his father, Charles, an Irish immigrant, World War I veteran and former police officer, being an alcoholic and unable to hold a job. Henry was a Marine in World War II and Korea, and joined the NYPD in 1952. He got married in 1955. Like his grandson Danny, Henry is socially conservative and hates the political correctness of modern law and order. His wife of 46 years, Betty, died December 2, 2001. It is later revealed that Henry and Betty had another son, Peter Christopher, who died of leukemia at the age of 18 months, over a year before Frank was born.
In "Bad Blood", it was revealed that he once rode with one of the first female patrol officers, Colleen McGuire (Anita Gillette). Henry admitted that they both had romantic feelings for each other, but they never acted on them since he was married. He had his boss reassign Colleen to a different partner to avoid putting his marriage at further risk, but remained good friends with her. In "Stomping Grounds", it was mentioned that Henry, during his days as a Detective with the Vice Squad, transferred out of the unit when he started to see every woman on the street as a hooker. In "Town Without Pity", Henry mentioned that during the New York City blackout of 1977 he was stationed in the South Bronx.
Nurse Linda Rose Reagan (née O'Shea) was Danny Reagan's wife. She was portrayed by Daytime Emmy–nominated actress Amy Carlson.
The wife of Danny from 1996 to 2017 and mother of their two sons. She loves her husband and the Reagan family, but at times, Danny's obsessive attitude toward collaring criminals makes her wonder whether he views his job as a higher priority than his family. In seasons one and two, she is a stay-at-home mom, but she returns to her nursing job at St. Victor's Medical Center in season three.
She has an older sister, Wendy (Laurie Williams), and a niece, Sofie, who is a fashion model. She also has a brother, Jimmy O'Shea (Kevin Dillon), who has been in and out of trouble with the law.
In "New Rules", Linda is shot at the hospital by a teenage gangbanger who had been ordered to kill a witness, but she eventually makes a full recovery. In "Under the Gun," Linda is mugged while working a community health van in the projects, and uses her father-in-law's influence to bypass the New York City pistol permitting process to obtain an unrestricted concealed carry permit and buys a .38 Special Smith & Wesson Model 36 revolver. Ultimately she decides she does not want to carry after all, and gives the pistol to Danny.
On May 28, 2017 (between seasons 7 and 8), Linda died in a medivac helicopter crash while tending to a patient being air lifted to the hospital. It was later implied in the season 9 premiere episode that the Mexican cartel hitman known as the Panther had been responsible for the aforementioned helicopter crash.
Nicole Reagan is Erin Reagan's daughter, and Frank Reagan's granddaughter. She is portrayed by Sami Gayle.
Erin's daughter, born October 14, 1996, aspires to become an officer like the rest of her family. As of "Old Wounds", she is 16 years old. In season five, she is a high school senior preparing for college; in season six, she is attending Columbia University, her mother's alma mater, and graduates at the end of season 9. She is a very curious young girl and is not afraid to question her uncle Danny and great-grandfather about police matters, often challenging their old-school conservatism. During the early seasons her willingness to be a nonconformist was emphasized by her short hair, but in later seasons she grew it out. She wanted to join the family business as the first female Reagan to be a cop. In season 8, Nicky takes the police exam, over her mother's objections. In season 10, Nicky is offered a job in San Francisco, and later accepts. She appears in only one episode of season 11.
Jamie's partner and eventual wife, Officer Edit Marie "Eddie" Janko Reagan (first name pronounced "eh-DEET") is of mixed Hungarian and Serbian descent. Feisty and strongly opinionated, she is very passionate when it comes to her job. She is portrayed by Vanessa Ray.
Eddie's mother, Lena Janko (Christine Ebersole) immigrated from Serbia and Eddie herself is fluent in the Serbian language, which comes in handy when Danny recruits her to bust a sex trafficking ring. Her Hungarian-born father, Armin Janko (Michael Cullen), was a financial advisor before his company was revealed to be involved in a Ponzi scheme, ruining a lot of good people. As a result, he is serving a prison sentence. He gets a lighter sentence after busting a prison guard drug ring. Later, when he is released from prison, he briefly lives with Eddie and Jamie until Eddie's mother allows him to live with her.
In "The Bullitt Mustang", Eddie is one of several police officers charged with official misconduct by the acting New York County District Attorney for fixing her 90-year-old neighbor's parking tickets; the charges are subsequently dropped after Frank and Erin work out a deal.
In "Back in the Day", Eddie reveals her aspirations of making detective, having signed herself and Jamie up for a surveillance assignment for one of the precinct's detectives. While awaiting their target, Eddie chose to remain at her post when Jamie chose to respond to an officer-down call, which proved to be false. This led to a brief conflict between them, with Jamie threatening to get a new partner if she ever goes against an emergency call again.
There has been significant romantic tension between Eddie and Jamie since the middle of season four, the two even sharing a kiss. Despite their attraction, Jamie had chosen not to act on his feelings after learning that Renzulli would reassign them to new partners per NYPD protocol. Nevertheless, there continued to be romantic tension lingering between the two, which had become much more apparent in "Personal Business" when they both acknowledged to each other how they feel, leading to another kiss. Despite this, they agreed not to further act on their feelings since they don't wish to jeopardize their partnership.
However, after a life-threatening situation in the season 8 finale, Jamie and Eddie fully accepted their feelings and got engaged. When they announced their engagement to the Reagan family, Frank offered Eddie her choice of a new precinct assignment. However, Jamie pointed out that there is no actual regulation prohibiting married NYPD officers from being partnered on the job. Therefore, they have decided to remain partners as well. In Season 9 Episode 1 "Playing With Fire", however, after Frank contemplates issuing an official written rule because of his concerns for such an arrangement, Eddie tells Jamie that all she wants is for them to be a couple. Jamie later announces to Frank that he had scored at the top of the Sergeants' Exam (Frank had not yet looked at the scores and was under the impression that he had declined to take it) and has decided to accept the promotion. This, therefore, ends his patrol partnership with Eddie and resolves their conflict. Frank then gives his blessing for the marriage, saying he couldn't be happier for Jamie and Eddie.
Jamie's promotion to Sergeant and transfer to the 29th Precinct results in the precinct commander transferring out several patrol officers whom Jamie catches in what appears to be either an internal brawl or a Fight Club-like activity in the precinct locker room. Jamie recommends the transfer of six officers from the 12th, including Eddie, to the 29th to replace them. Eddie initially declines her transfer, telling Jamie she needs the space for her own career to grow. Despite this, she quickly changes her mind after visiting Jamie at the 29th while in civilian clothes and overhearing several patrol officers disparaging him in his absence, as well as hearing from some of the other transferees how rough their new assignment at the 29th is. After her transfer to the 29th, she was initially partnered with Officer Maya Thomas (Yasha Jackson) until Thomas was dismissed after getting caught stealing cash from crime scenes. Eddie subsequently partnered with Officer Rachel Witten (Lauren Patten), whom Frank had dismissed for racial profiling and then reinstated after a few months.
Eddie's mother Lena makes her first appearance in "By Hook or by Crook". Despite her husband's conviction and imprisonment, she has tried to maintain her past wealthy lifestyle. Upon meeting Jamie and learning of Eddie's engagement to him, she openly expresses doubt about his ability to give her the lifestyle she had been raised with. However, she soon warms up to him when Jamie refuses to be intimidated by her and is happy with the relationship.
The Season 9 finale, "Something Blue", ends at the start of the wedding Mass with Archbishop Kearns (Stacy Keach) officiating; as Armin remains incarcerated, Frank walks Eddie down the aisle at her request. In the Season 10 premiere, after she and Jamie referred to herself as "Eddie Janko-Reagan" a few times, they decided she would remain "Officer Janko" on the job and "Mrs. Reagan" at home. Upon the couple's return to duty after the wedding, their precinct commander, Captain Espinoza (Luis Antonio Ramos), switched Eddie and Officer Rachel Witten (Lauren Patten) to the night shift under Sergeant McNichols (Stephanie Kurtzuba) to remove Eddie from Jamie's chain of command. In later episodes, however, Eddie is still seen to be under Jamie's authority, for example assigning her to partner with an officer who had difficulty after the death of an earlier partner.
As a uniformed patrol officer, Eddie drives a patrol car on duty and carries a Glock 19 in 9×19mm as her duty weapon. Her shield number is 68921. As of Season 9 she is wearing the NYPD Excellent Police Duty award.
Mentioned but not portrayed on-screen:
Detective 2nd Grade Abigail Baker is a member of the Police Commissioner's (Detective) Squad who serves as Frank's primary aide. She was credited in Season 1 as "Det. Melissa Baker" but was referred to as Abigail throughout the season, and the name was changed in Season 2. Baker is portrayed by Abigail Hawk.
In "Manhattan Queens", Baker was harassed by Suffolk County Police Department Deputy Chief Sam DeLuca, who had a romantic interest in her. In the same episode, it is revealed that she is from Ocean Bay Park and her parents still live there. She speaks fluent Japanese. Frank mentions she is happily married in season 6 when questioned by his former partner Lenny. She subsequently becomes pregnant and gives birth during season 7. Having been with Frank for nine years as of season 8's "Heavy Is the Head", Baker longs for more active detective work despite Frank's assurances that he needs her and often leans on her detective instincts. She receives an offer to work for newly promoted Captain Bullman, who used to be her sergeant, but Frank refuses to let her resign. Frank reluctantly tells Abigail later that he found out Bullman mainly wanted to hire her to have someone in his ranks who could pull favors at 1PP.
Abigail's husband is Officer Brian Baker of the 65th Precinct (played by Jarid Faubel). They have at least two children. In "By Hook or by Crook", Brian is shot and critically wounded by a drug dealer who was released on bail after a murder conviction in Mexico was missed by a background check. Brian recovers, but in "True Blue", he shows signs of PTSD, which strains their marriage, and he is suspended and investigated by Internal Affairs after being caught on camera roughing up a suspect he was arresting.
Before becoming Frank's Deputy Commissioner of Public Information and de facto chief of staff, Garrett was a reporter. He has been married and divorced three times and has a stepson whom he has tried to keep out of trouble. Garrett and Frank have a rather complex relationship; for example, Frank often expresses dismay when Garrett comes into his office unannounced but also seemingly values his perspective. Furthermore, many episodes depict the two debating an issue regarding what information should or should not be released to the public. In "Nightmares", a woman in Atlantic City, New Jersey, accused him of rape, but the allegations were proven to be false when it was revealed that the woman in question was a prostitute who slept with rich married men and then blackmailed them. He is portrayed by Gregory Jbara.
Formerly the Organized Crime Control Bureau Chief, Dino Arbogast was promoted to Chief of Department (the highest-ranking uniformed police officer) by Frank after the retirement of the previous Chief, Ed Hines. Dino maintains this role for season 4, until the finale, when he's forced to resign after being caught on video committing lewd acts with an escort hired by a recently deceased brothel madam, and lying about it, and benching Danny in an attempt to keep the act from being discovered. He is portrayed by John Ventimiglia.
The Supervisor of the 54th Precinct's Detective Squad, Sergeant Sidney Gormley was Danny's boss for over four years. He was frequently exasperated by his subordinate. He lives in New Hyde Park with his wife, Sheila (Cady Huffman), has a son Brendan, a currently unnamed daughter, and, according to the certificate in his office, is a graduate of New York University. In "Flags of Our Fathers", Gormley mentions that he is a veteran, and that he lost a grandfather and two uncles in the service.
Early in season 5, Gormley is reassigned by Frank to One Police Plaza and appointed as Dino's replacement as Chief of department. However, due to Gormley only being a Sergeant at the time, and therefore not being high enough in rank to be eligible for Chief of Department (who must be at least a captain or higher), he is given the job title "Special Assistant to the Commissioner", which gives him the authorities of the Chief of department though not the pay grade or privileges. In this capacity, Gormley acts as Frank's liaison to the rank and file. He is later on promoted to Lieutenant. He is portrayed by Robert Clohessy.
The Mayor of New York City who appointed Frank Reagan to the position of New York City Police Commissioner. He lost the 2011 election to Carter Poole (David Ramsey), who succeeded him as mayor. While he is credited as the character "Frank Russo" in Season 1, his name is never actually mentioned. He makes a return appearance in Season 3 when his daughter is arrested by Jamie and Vinny for smoking pot. Here, his character is introduced as "Former Mayor Robert Levitt". He is portrayed by Bruce Altman.
Elected to the position of Mayor of New York City in 2011, Carter Poole and Frank butt heads on occasion, but the two have a mutual respect for each other that Poole says went back to his childhood when Frank was a beat cop in his neighborhood and used to look out for the children. In "Parenthood", it is mentioned that he attended Yale University and that he has an illegitimate daughter who does not know about him, aside from the fact that he is the mayor. In "This Way Out", he's shot in an assassination attempt during a town hall meeting by a mentally-challenged teenager who was tricked by a member of the Los Lordes gang operating out of the Bitterman Housing Projects. The shooting leaves the mayor paralyzed from the waist down, confining him to a wheelchair, but does not prevent him from discharging his duties as mayor. In 2015, he is reelected for another term as mayor. In 2017, he resigns as mayor because he is burned out and feels he is not the man to lead the city any longer. He is portrayed by David Ramsey.
The New York City Public Advocate under Mayor Carter Poole, Margaret Dutton ascended to the position of interim Mayor of New York City in 2017 after the Mayor's resignation. She is portrayed by Lorraine Bracco. As mayor, she is aided by Carlton Miller, who is portrayed by Mark Linn-Baker.
The Mayor of New York City as of Season 10. Introduced as the Mayor-elect in "Friends in High Places". His first encounter with a member of the Reagan family, after winning the election in a landslide, is with Erin when he offers his endorsement for her to run for election as District Attorney; Erin eventually learns that she is only one of four Assistant DAs to whom Chase has made that offer. Frank's first encounter with Chase is when Chase informs him that he intends to keep him on as Commissioner and that he would like to reinstate Frank's Stop and Frisk program among other more hardline law enforcement policies to protect the NYC tourist industry. He does add one condition: that Frank replaces Garrett Moore as DCPI with a more hardline deputy commissioner from a list of candidates provided by Chase. Simultaneously, Garrett receives an unsolicited job offer for a professorship at Duke University; he and Frank do some checking and discover that Chase's wife is on the board of directors at Duke. Frank and Garrett stand firm on Garrett staying, with a counteroffer to hire one of Chase's nominees as an assistant. Chase accepts, but tells them that once he is sworn in, "what I say goes." He is portrayed by Dylan Walsh.
The Inspector General of the NYPD, portrayed by Bebe Neuwirth. Kelly is a former member of the Essex County Prosecutor's Office in New Jersey. In the season 4 finale, Peterson tells Commissioner Reagan about her intent to resign, after finding that she does not have enough "professional animosity" toward the NYPD due to becoming too close to Frank. In season 8, Peterson returns as the Corporation Counsel of New York City.
The Speaker of the New York City Council, portrayed by Whoopi Goldberg. She is an often adversary, sometimes ally of Frank in his conflicts with the Office of the Mayor and other city offices and agencies and with the Council itself.
The Governor of New York, known for his thin skin, which Frank describes as "thinner skin than a grape", and tendency to "overreach". He is portrayed by David Zayas.
The Archbishop of New York, Kevin Kearns occasionally comes to Frank for help with delicate matters involving the city archdiocese or one of its members. He also officiated Jamie's marriage to Eddie in season 9. He is portrayed by Stacy Keach.
Fire Commissioner Stan Rourke, Frank's counterpart in the Fire Department of the City of New York (FDNY), portrayed by Dan Lauria. The two have a testy and sometimes openly hostile relationship stemming from the nearly centuries-old rivalry between the two departments. In "With Friends Like These" (Season 6 Episode 4), a brawl between police and firefighters at a crime scene escalates into open unwillingness of both departments to cooperate with each other. In "Friends in High Places" (Season 10 Episode 8), Rourke and several of his senior officers are arrested by the NYPD after a retirement party for one of the officers gets out of hand.
Detective 1st Grade Jackie Curatola was Danny's previous partner; she is divorced and is regularly the recipient of passes or ogling from her uniformed colleagues and perps alike, much to her annoyance. In 2012, Jackie took early retirement from the NYPD after starting to show signs of burning out. As a detective with the NYPD, Jackie carried a Glock 19 in 9×19mm as her duty weapon. As of 2023, Jackie is a Police Chief in a small town. She is portrayed by Jennifer Esposito.
Assigned to replace Detective Curatola in 2012, Detective Kate Lansing worked with Danny for almost three months. She transferred back to Internal Affairs after the arrest of Captain Derek Elwood (Nestor Serrano), who framed Danny for possession of narcotics in order to prevent him from discovering his gambling problem. She is portrayed by Megan Ketch.
Danny's partner since 2013 (and someone Danny has known for almost 20 years), Detective 1st Grade Maria Baez previously spent three years with the NYPD's Joint Bank Robbery Task Force until it was disbanded in 2011. In "Bad Blood", it is revealed that she has an older brother, Javier (Kirk Acevedo), who is a recovering drug addict, and her mother, Carmen Baez (Saundra Santiago), and her sister, Ana Baez (Liza Colón-Zayas), are introduced in "Stomping Grounds". Before transferring to the 54th Precinct, Maria fell hard for Detective Jimmy Mosely (Johnathon Schaech), but their relationship fizzled out when he refused to leave his wife for her.
In "Partners", Javier revealed that he is an informant for the DEA against a drug cartel; he dies saving Maria's life in a raid on that cartel. In "Love Stories", she and Danny are awarded the NYPD Medal for Valor for their actions in "Partners". During season 7, Danny claims that Baez has difficulty establishing or maintaining romantic relationships. In the season 12 finale "Silver Linings", Baez adopts a newborn baby girl, whose biological mother Elena Marquez was assassinated with a bomb on the orders of Arturo Muñoz, whom she was testifying against. She is portrayed by Marisa Ramirez.
The new Commander of the 54th Precinct's Detective Squad, Lieutenant Dee Ann Carver is Danny's strict, by-the-book boss who took over after Sgt. Gormley was transferred to 1PP. She is the adoptive mother of a baby girl whose father committed suicide in front of her and Danny, despite their best efforts to talk him down. She is portrayed by LaTanya Richardson Jackson.
Mike Gee is a 20+ year veteran on the police force who initially retired, but went back to work after his son was diagnosed with an illness. Introduced as a fellow detective at the 54th, he was promoted to lieutenant and commanding officer of the 54th Precinct Detective Squad by the season 11 episode "Triumph Over Trauma". Portrayed by Eric B.
Gates is a Texas Ranger who has traveled to New York to work with Danny, first to arrest a Texas fugitive who is involved with a New York drug gang (Season 10 Episode 14 "Fog of War"), then to lead a task force to intercept a drug shipment that has slipped through the US-Mexico border (Season 12 Episode 10 "Old Friends"). Danny and Gates frequently trade barbs but have a generally amicable relationship with mutual respect, particularly since both are former Marines, with Gates being a graduate of Marine Sniper School. Portrayed by Lyle Lovett.
Maggie is a medium who occasionally helps Danny and Baez with their cases. Maggie openly encourages Danny to move on following Linda's death, making Baez suspicious of her motives. Portrayed by Callie Thorne.
Erin's ex-husband and Nicky's father, Jack Boyle is a formidable defense attorney. Due to his actions after the divorce (including moving away and not keeping in contact with his daughter), Jack is not very well liked by the adults in the Reagan family (although his nephews, Jack and Sean, are both excited to see him when he returns to New York). When Danny was framed for narcotics possession, Henry hired Jack as his attorney.
Jack and Erin briefly got back together after surviving a courtroom hostage crisis, but Erin ended it when it became clear that Jack was only interested in casual dating and didn't want to commit to a marriage.
Jack did return in 2017 to represent a man that Erin is trying to convict. This time Jack came out on top. Erin also learned of Jack's relationship with a woman who is a few years older than Nicky, which did not last long. It later seasons, it is revealed that Jack and Erin were continuing to see each other in a casual relationship. Jack is portrayed by Peter Hermann.
A retired detective for the DA's Investigations Unit who assists Erin with her cases. He and Danny don't personally get along, but are willing to work together when necessary. In "Friends in Need" it is revealed that his cousin is Joey Ruscoli / Razzano (Anthony DeSando), and his aunt is Sophia Ruscoli (Catherine Wolf). In "Good Cop Bad Cop" it is revealed that his mother is Lucille Abetemarco (Suzanne Shepherd). In "The Brave" it is revealed that his ex-wife is Vivian Abetemarco and his daughter is Sophia Abetemarco (Isabel Harper Leight). In "Disrupted" the role of Vivian Abetemarco is from thus on played by Kate Miller. In "Past Tense" it is revealed that his long-lost former mobster half-brother is Leo Stutz (Erick Betancourt). He is portrayed by Steve Schirripa.
Erin's boss in the first season, Charles Rosselini is the New York County District Attorney with aspirations of higher office. He is portrayed by Bobby Cannavale.
The Bureau Chief of the Manhattan District Attorney's Trial Bureau, Amanda Harris promoted Erin to Deputy Bureau Chief. She almost fires Erin after she calls her out on violating Brady Rules by not providing the defense with video footage that may have exonerated a previous rape suspect; Harris ends up keeping Erin, saying that she needs someone like her to keep her in check. Regardless of this, Harris is eventually arrested after Erin finds out that she has a long-standing deal with a recently deceased high-profile madam who has her people seduce high-profile New Yorkers of major influence – like high-level cops, politicians, pro athletes, and various celebrities – and get them on tape in order to guarantee their assistance whenever she needs it. (Whether this assistance is solely for cases or possibly for darker, personal reasons is left open to speculation.) She is portrayed by Amy Morton.
A defense attorney Erin met on a speed-date. He was an Assistant District Attorney in Brooklyn for twelve years before leaving to join private practice in 2008. After Bureau Chief Amanda Harris was fired, McCoy was appointed the interim New York County District Attorney. This caused Erin to break off their relationship, saying she can't sleep with her boss. As the interim DA, McCoy came into conflict with Commissioner Reagan when he announced that the DA's office did not plan on prosecuting petty marijuana possession charges. He is portrayed by Holt McCallany.
District Attorney Samar "Sam" Charwell is Erin's new boss after she is promoted to Bureau Chief in season 9. At the beginning of season 11 he's fired and prosecuted for corruption. He is played by Aasif Mandvi.
A member of the DA's Investigations Unit who assists Erin with her cases. In 1995, McBride's mother was murdered in an unsolved robbery. When Erin finds the case in a cold-case pile, she runs DNA found at the scene, which reveals what McBride already suspected but was afraid to confirm: that his father had been responsible.
