Laval police identified the man as Ian Davidson and said an autopsy has concluded he killed himself with a sharp object.
The 33-year veteran of the Montreal police force was found dead in a hotel room on Wednesday and material found in the room was impounded by Laval investigators.
At the time, Laval police confirmed that a man's body had been found inside the hotel, but they did not release his name.
Montreal police drew a connection between the death and an investigation into allegations that a retired detective on their force offered names of informants to the Mob in exchange for money.
Davidson had not been charged and the alleged offences occurred after his retirement in January 2011.
Several news outlets reported this week that the former cop's body was found in the Laval hotel room on Wednesday — the same day Montreal La Presse named him as the alleged mole.
Montreal's police chief held a news conference on Tuesday and promised swift action after reports the retired officer allegedly tried to sell information on informants to the Mafia.
Marc Parent said the former intelligence analyst was one of a handful of people who had access to a confidential list of names.
Several reports said he allegedly had contact with a lawyer who represents organized crime figures and that he offered information in exchange for a six-figure sum.
He allegedly gave the lawyer four names to show he was serious — people who have since been contacted by police, Parent said.
Police say the information that led to the allegations surfaced in April 2011 during a wiretap investigation.
An ongoing internal investigation revealed that none of the informants was deemed to be at risk, Parent said. The force is now reviewing computer security and protocols for having access to sensitive information.Suggest a correction
