Three men accused of orchestrating Johnnie Raposo’s murder before being caught up in a major drug-trafficking bust are believed to have ties to the Mob and outlaw bikers across the country.

Exactly why the trio — one of whom is still on the loose and has ties to Ottawa and Montreal — allegedly hired Dean Wiwchar to kill Raposo in Little Italy last summer is unclear but there has been speculation a debt was involved.

But while Toronto Police homicide detectives have insight into the slaying that they’re not revealing, organized crime specialists suspect drugs and drug ripoffs may have prompted the alleged hit on the 35-year-old.

One Mob expert believes the hit on Raposo has ties to the criminal underworld in Montreal, home of the notorious Rizzuto crime syndicate.
