Rizzoli & Isles

• Angie Harmon as Jane Clementine Rizzoli: a Boston detective in the Homicide Unit. From an Italian American family, Jane is brash, sarcastic, and often prickly but also a confident and independent woman as well as a brilliant detective. She is the tomboy daughter of an overprotective mother, Angela, and an insensitive father, Frankie Sr. Her parents eventually separate. She is extremely competitive, especially with her younger brother, Frankie (also a cop), who is often caught in her shadow. Jane can tackle a perp like a linebacker. She rarely lets her guard down with anyone, except her best friend, Maura Isles. She is something of a slob; her apartment has been shown on several occasions to be quite messy, and in one episode she claimed to have just opened a box of cereal five years after originally buying it. As a child, she was slightly chubby, earning her the nickname "Roly-Poly Rizzoli". She mentioned in one episode that she played field hockey as an attacker in junior college. She is the eldest Rizzoli sibling,[3] and graduated from high school in 1994, which puts Jane's birth year at 1976.[4] She is hopeless with men and allergic to dogs, but she winds up taking in Jo Friday, a stray dog rescued by her former partner, Korsak. Raised in the blue-collar Boston suburb of Revere, Jane has fought long and hard to win the respect of her colleagues, but it is her relationship with her equally stubborn mother, Angela Rizzoli, that sometimes proves to be her biggest headache. During her time on the force, she had a traumatic experience at the hands of a serial killer known as "The Surgeon", Charles Hoyt. While trying to rescue one of his victims, she was taken by surprise from behind and almost became a victim herself. She has matching scars in the center of her palms where Hoyt stabbed her with scalpels, keeping her pinned to the ground. Her original partner, Vince Korsak, saved her life, and Jane survived the brutal, near-death attack by Hoyt. Although she put Hoyt behind bars, she is still haunted by him. She learned that she was pregnant at the end of season four, owing to a liaison with her old boyfriend Casey, but lost the baby midway through the fifth season when she was attacked while protecting a key witness in a case. In the final season, Jane takes a new job as an instructor at the FBI Academy in Quantico, Virginia, and works her final case with the Boston PD in the series finale, "Ocean-Frank".
• Sasha Alexander as Dr. Maura Dorothea Isles: the Commonwealth of Massachusetts' Chief Medical Examiner. Isles is a forensic expert working at the Boston Police Department and Jane's best friend. Maura is a walking encyclopedia, able to spout out facts regardless of whether or not they are relevant to a case. She has a pet tortoise named Bass, after noted forensic anthropologist William M. Bass. Maura is not easily ruffled and has a steady temperament. She absolutely loves examining dead bodies, but she has a tendency to diagnose living people a little too often. She is the adopted only child of a wealthy family. In high school, she was nicknamed "Maura-The-Bore-A" because her classmates thought she was boring. She is always impeccably dressed and is known around the force as "Queen of the Dead"; her ring tone on Jane's phone appropriately plays Chopin's "Funeral March". Maura is the complete opposite of Jane, though they are best friends. Though Maura is socially awkward and has trouble with men because of her brutal honesty and habit of revealing all their medical conditions, she is not awkward around Jane. She can analyze x-rays and blood chemistries and can slice open muscles and organs but possesses no scalpel with which to dissect human emotions. Maura also cannot lie; if she does, she breaks out in hives. It is later revealed that her biological father is an Irish crime boss named Paddy Doyle, something she finds out while investigating her half-brother's death. She finds out in the episode "What Doesn't Kill You" (3.1) that her father told her biological mother that she died on the day she was born, August 7, 1976. She subsequently visited a cemetery containing a gravestone with the name "Baby Maura Doyle" on it. In the series finale, "Ocean-Frank", Maura takes a sabbatical from the ME's office to go to Paris and work on her novel.
• Lorraine Bracco as Angela Rizzoli: Jane, Frankie and Tommy's overbearing mother. Angela is fiercely protective of her children, saying she has not slept since Jane decided to become a cop. Angela wishes Jane could be a little more feminine and is constantly trying to set her up on dates. After her divorce, she spent some time working in the precinct's café, and dated Lieutenant Cavanagh, but she quit the job and broke up with Cavanagh when she decided that she needed to re-evaluate her life. She currently works at the bar that Vince Korsak bought and that they all frequent.
• Bruce McGill as Vincent "Vince" Walter Korsak: Rizzoli's former partner. The two maintain a close bond after years of working together, but Korsak is clearly bothered that he is no longer partnered with Jane. He seems to care for her like a daughter and is nearly as protective of her as Angela is. It is revealed in the series pilot that he saved her life from Hoyt. He will drop whatever he is doing on a moment's notice to rescue an animal, and enjoys watching videos of dogs on the Internet. After remaining a detective for nearly his entire career, Korsak was finally promoted to sergeant-detective in season two, and took the lieutenant's exam in season five. In preparing for retirement, Vince bought the local bar that they all frequent, the Dirty Robber, and employed Angela. He was a US Marine and served during the Vietnam War. Korsak has been divorced 3 times. Despite the jokes that he is behind the times, he is very wise and observant. He has several hobbies, including playing guitar and sailing, Maura even once asked him for his expertise on seaman knots and skills. In the sixth season, he became engaged to Kiki, and he married her in the sixth season finale. In the series finale "Ocean-Frank", Korsak retires from the Boston PD after a thirty-two year career, using his accumulated available vacation time to retire eight weeks early so that he could coincide with Jane and Maura's own new plans for their lives.
• Lee Thompson Young as Barold "Barry" Frost (seasons 1–4): Rizzoli's second partner. Adept with computers and technology, he is terrified of dead bodies and becomes ill at the sight of blood. He is very protective of Jane. In the season five premiere, he is killed in a car accident while returning from vacation (due to Young's suicide in 2013). In the season five finale, the team establishes the Barry Frost Memorial Scholarship, intended for students who are academically gifted and who seek to go into professions that would help others but lack the resources to do so.
• Jordan Bridges as Francesco "Frankie" Rizzoli, Jr.: a police officer and Jane's brother. He looks up to Jane, but does not like feeling caught in her shadow as he tries to make his own way on the police force. Like all the men in Jane's life, Frankie is more protective of Jane than she would like. He is a cop against his mother's wishes, and he sees his sister as a role model. Frankie is promoted to detective in season four, and he starts taking night classes in computer science to increase his skill set in season five. In season seven, he begins a romantic relationship with Nina and eventually successfully proposes to her.
• Brian Goodman as Sean Cavanaugh (seasons 3–4; recurring, seasons 1–2, 5): the lieutenant of the Boston PD's Homicide Unit. Fiercely loyal to Jane and an old friend of Korsak, Sean is willing to bend the rules for his guys. It is later discovered that Sean lost his wife and son in a fire (set by Paddy Doyle) back when he and Korsak were rookies. Sean dates Angela Rizzoli for a period of time but they eventually break up.
• Idara Victor as Nina Holiday (seasons 6–7; recurring, season 5): a crime scene analyst and computer technician. Formerly a detective in Chicago, Holiday transferred to Boston Homicide to hone her analytical skills in an office-based environment.[5] Following Nina's being shot by Alice Sands in the sixth-season finale, Frankie Rizzoli begins a romantic relationship with her in the seventh season, and later successfully proposes to her in the finale.
• Adam Sinclair as Dr. Kent Drake (season 7; recurring, season 6): a lab technician, and Maura's new assistant starting in the sixth season. He is a Scot with a military background, having served in the Middle East. In the series finale, "Ocean-Frank", Kent is set to oversee the Commonwealth of Massachusetts' Medical Examiner's Office during Maura's sabbatical.

• Annabeth Gish as Alice Sands. Alice McFadden was born into a distinguished law enforcement family, but she dropped out of the police academy while Jane was enrolled. Alice was second in her class behind Jane, after having been the best at everything prior to then. This feeling of inferiority resulted in her dangerous fixation on Jane, which led Alice to turn to a life of crime. She inserted herself into a circle of tunnel residents and was able to make them do her bidding, but she ended up being arrested. After being released with help from lawyer Phillip Dayton, Alice began her revenge plans on Jane. Following a shootout at Korsak's wedding reception, Jane seemed to make a personal vendetta against Alice. Jane finally corners Alice, who has taken a teenager hostage, and shoots her dead. This leaves her team to wonder if Jane shot her in the line of duty or as an act of vengeance.
• Tina Huang as Susie Chang, the senior criminalist of the Boston Police Department's crime laboratory. She has described herself as having a very physical memory. For example, when circumstances required her to take point in an investigation, she made various dioramas to explain her reasoning. In the third-season episode "Class Action Satisfaction", she is revealed to be a nudist. She is killed in the sixth-season episode, "Misconduct," as part of a complex plan to frame the forensics department for poor handling of a recent case, but the subsequent investigation exposed the killer's true agenda.
• Donnie Wahlberg as Lieutenant Joe Grant, an old rival of Jane's who has known her since childhood. He constantly made fun of her, calling her "Frog Face" and "Roly-Poly Rizzoli" because she was slightly chubby when she was younger. When he leaves for Washington, D.C., after being appointed as the liaison between Boston and Homeland Security, he claims that he has liked her for a very long time.
• John Doman as Patrick "Paddy" Doyle, an Irish-American crime boss and the biological father and protector of Maura Isles. To protect her from his diehard father, Paddy claimed Maura had died as a baby and made sure she was adopted.[6]
• Jacqueline Bisset as Constance Isles, a visual artist and the adoptive mother of Dr. Maura Isles. She loves Maura but is sorry that they don't have a close relationship.
• Colin Egglesfield as Thomas "Tommy" Rizzoli, the well-meaning, good-looking but dim younger brother of Jane and Frankie. Convicted for running over a priest (non-fatally) in a crosswalk on his third DUI violation, he returns to the family fold following his release from prison. As of the season two episode "He Ain't Heavy, He's My Brother", he is 32 years old. He tries to kiss Maura to pay her back for her kindness, but she stops him and he develops a crush on her as he works on starting a new life. He later fathers a child, TJ, and grows up a lot.[7]
• Chris Vance as Charles (Casey) Jones, an old flame of Jane's from high school, reunited with Jane during season two. A US Army officer assigned to the Middle East, he returns to Boston in season three but breaks up with Jane because of injuries that left him partially paralyzed below the waist. He returns in season four's first episode after a successful operation and proposes to Jane, but when he receives the offer of a promotion to colonel, he decides to stay in the army, leaving Jane behind, since she was unwilling to leave her life. He is aware that Jane was pregnant with his child, but he respects her decision to raise the child alone, as he had also made the choice to return to the army; she loses the baby midway through the fifth season after being attacked while protecting a witness.
• Darryl Alan Reed as Rondo, a man with access to information in the criminal world. Although Jane initially dismisses his offer to be her confidential informant, he does become her informant later on, and he provides Jane with information from the criminal world. He has also been shown to have a comical character persona, similar to Larry Laffer. He frequently hits on Jane, calling her "Vanilla", and he eventually develops a friendship with Angela, referring to her as "Mrs. Vanilla". He is revealed to be a former jazz singer in "This Is How a Heart Breaks" but refuses to discuss his past life or to sing.
• Billy Burke as Gabriel Dean, an FBI agent often seen working with the Boston Homicide detectives and the Medical Examiner's Office. He later becomes romantically involved with Jane but she ends this relationship when he tries to use her as part of a plan to capture Paddy Doyle that forced Jane to shoot Paddy.
• Chazz Palminteri as Francesco "Frank" Rizzoli Sr. – father of Jane, Frankie, and Tommy. He owns and runs a plumbing business called Rizzoli and Sons. He and Angela separate and then divorce after the first season. He later tries to have their marriage annulled so that he can remarry in a Catholic ceremony. He returns to announce he has stage 2 prostate cancer, and, despite the news, his family finds it difficult to overlook his past transgressions.
• Matthew Del Negro as Giovanni Gilberti, a dimwitted former classmate of Jane's and a blue-collar auto mechanic. Initially attracted to him against Jane's advice, Maura is quickly nauseated by him. To get him off their backs and halt future advances, Maura and Jane pretend to be dating, which Giovanni repeats in a later episode set at Jane's high school reunion.
• Michael Massee as Charles Hoyt, a sadistic serial killer who kidnapped and stabbed Jane in both hands and continues to threaten Jane, even from behind bars. Hoyt appears in several episodes, including "See One, Do One, Teach One" (episode 1), "I'm Your Boogie Man", and "Remember Me". In the episode "See One, Do One, Teach One", Hoyt and the apprentice are shown attending medical school with Jane. Jane shoots and kills the apprentice and throws a flare at Hoyt. Jane then shoots him in the hands and says, "We match." In the episode "Remember Me", Hoyt, dying of cancer, lures Jane and Maura into his hospital room with the assistance of a new apprentice, intending to kill Jane before he dies, but Jane manages to get the upper hand and stabs and kills Hoyt with a scalpel while saying, "I win." Despite his death, he continues to haunt Jane and the team, and he was mentioned in the next two seasons after his death. While dealing with the murders committed by Dennis Rockmond ("Melt My Heart of Stone"), Jane speculates that he may be an apprentice of Hoyt due to the ritualistic nature of his crimes, and "No One Mourns the Wicked" saw the team deal with a forensic pathologist and her son (conceived by her father's abuse) who were committing murders inspired by Hoyt.
• Sharon Lawrence as Dr. Hope Martin, Maura's biological mother, who was told by Paddy Doyle that Maura died as a baby. She is a noted medical doctor with another, much-younger daughter, Cailin.

• Alexandra Holden as Lydia Sparks, a ditzy young woman who is heavily pregnant when she is befriended by Angela. It is soon revealed that the child she is carrying is the child of either Angela's son Tommy or Angela's ex-husband Frank. Eventually the child is known as T.J., for "Tommy Junior", after a test confirms that Tommy is the father.
• Jaz Sinclair as Tasha Williams (season 5), a high school student who witnessed a shooting, saved by Jane from the shooter.
