A former narcotics detective, Fin joins the SVU squad in the season 2 premiere "
Wrong Is Right", as a replacement for
Monique Jeffries (
Michelle Hurd). He is then paired with
Det. John Munch (
Richard Belzer). While in the Narcotics Division, Fin worked undercover regularly. He would often spend weeks or even months at a time in various alternate identities. He left Narcotics and transferred to SVU when his partner took a bullet that was meant for him. Fin initially has a rocky relationship with his colleagues in SVU, especially with Munch and
Olivia Benson (
Mariska Hargitay). Unlike them, he views justice in a "black and white" manner and believes that all criminals should be punished, regardless of the circumstances under which they commit the crime. He also tries to separate his private and professional life as much as possible and keeps a tight rein on his emotions, refusing to talk about his problems or to admit that the grisly nature of his work often affects him. For example, it takes him nearly a year before he opens up to Munch about his former partner getting shot. In the Season 9 finale "Cold", Detective
Elliot Stabler (
Christopher Meloni) suspects that Fin tipped off his temporary partner
Chester Lake (
Adam Beach), who is suspected of murder, before he and Benson could take Lake into custody. Stabler checks Fin's phone records, infuriating him. Near the end of the episode, Stabler apologizes for not trusting him, but Fin dismisses his apology, telling him, "You'll still be the same rat-bastard tomorrow." Afterwards, he requests a transfer from the squad. However, three months later, Fin later learns from
Captain Donald Cragen (
Dann Florek) that the transfer had become bogged down in
red tape, keeping him with SVU: Fin later discovers that the person in charge of transfer paperwork was previously a colleague of his in the narcotics unit who holds a grudge because his ex-wife started calling Fin after their divorce. Hearing this, Fin resigns himself to the likelihood that his transfer will not happen anytime soon. No further mention of his transfer request is made after this point. Fin and Stabler mend their relationship somewhat, however. While they are never friendly, they do respect each other, and sympathize with each other over the dual burdens they both face from being police officers and fathers. When
pedophile Jake Berlin (
Tom Noonan) posts a picture of Stabler's daughter on his website, Stabler beats him up, but Fin covers for him and praises him for showing restraint; he later admits to Benson that, had Berlin posted pictures of his child, he would have killed him. Years later, when Stabler, who quit SVU in 2011, returns to New York after spending 10 years in Italy, Fin is the first person he calls. After Munch retires from SVU, Fin is partnered with Detective
Amanda Rollins (
Kelli Giddish), who had transferred to Manhattan SVU from a precinct in her native
Atlanta, Georgia. They have a good working relationship, but it is tested when Rollins'
gambling addiction begins to interfere with her work. When Rollins loses thousands of dollars at an underground casino, Tutuola gives her some money and tells her to get help, and he is the first to defend her when she becomes a suspect in a corruption case involving the casino. When he learns that she had been cooperating in a
sting operation, he is hurt that she didn't tell him, and loses some respect for her. They repair their relationship, however, after she reveals that she had been raped years earlier in Atlanta by her then-superior officer, Deputy Chief Charles Patton (
Harry Hamlin), who has a long history of sexually abusing the female detectives in his squad. Along with Benson and ADA
Rafael Barba (
Raúl Esparza), Fin helps her bring Patton to justice for raping his latest victim, Detective Reese Taymor (
Dreama Walker). In "Making a Rapist",
DNA evidence exonerates Sean Roberts (
Henry Thomas), a man Fin had arrested for rape in 2000. When the evidence of the rape and murder of the victim's daughter points to Roberts, Barba accuses Tutuola of framing Roberts as revenge for tarnishing his arrest record. Roberts is later convicted after he confesses in court. In the season 19 premiere "Gone Fishin'", Fin recruits some men from
Cuba to kidnap fugitive serial rapist Byron Marks (
Will Chase) and bring him to New York. Marks' attorney and Cuba's U.N. permanent mission representative accuse Fin of kidnapping Marks and violating
extradition laws. When Benson, now a Lieutenant and SVU's commanding officer, demands an explanation, Fin says that he had encountered Marks by chance while vacationing in Cuba, a lie Benson chooses to accept. At the end of the episode, Marks is found guilty of rape and goes to prison. In a deleted scene from the season 18 episode "Net Worth", it is revealed that Fin passed his sergeant's exam and became an NYPD Sergeant. In "Real Fake News", he and Benson discuss him passing the exam, but he says he is waiting to be appointed. In "Mama", he receives his sergeant's orders to go to the 21st precinct, but he manages to get transferred back to SVU. In "Sightless in a Savage Land", Fin becomes engaged to Sergeant Phoebe Baker (
Jennifer Esposito), his former partner from Narcotics. In "Wolves in Sheep's Clothing", however, they call off the wedding after deciding at the last minute that they like their relationship the way it is.
