Vin Makazian was a Newark, New Jersey police detective who fed information to Tony Soprano. Tony also used Vin as an investigator, engaging Vin to find information about Dr. Melfi when Tony first started therapy in 1998. Vin was over-enthusiastic in this role, having misunderstood the relationship between Tony and Dr. Melfi as a romantic one, not a professional one. He tailed her and pulled her car over, beating up her companion unprovoked and chastising her for being out with a man he refers to as "hamburger, when you've got prime rib at home." Vin later told Tony that he had taken photographs of Melfi undressing from outside her home, if he's interested, to which Tony replies with disgust. Vin was responsible for informing Tony that Sal "Big Pussy" Bonpensiero was a rat, prompting Tony's suspicions of Pussy, though this was later seemingly dismissed when Tony found out Vin owed Pussy $30,000 dollars in gambling debts, and Vin would like to see Pussy taken out to absolve him of said debt.
Makazian frequented an illegal brothel and had a relationship with the madam there. He was arrested at the brothel along with Soprano crime family capo Raymond Curto during a police raid. Vin later committed suicide, by leaping off the Donald Goodkind Bridge shortly after he was released from jail. Tony later visited the madam with whom Makazian had a therapeutic relationship, and she divulges to Tony that Makazian viewed him as a friend and, like Tony, was prone to depression. This leaves Tony depressed because he had always treated Makazian with disdain and never showed him any respect or kindness.
