In November 2013, Mr. Oliverio gave up the retention of four handguns that he owned, after the Quebec Firearms Controller refused to renew his licenses, "because the Coliseum investigation established that he was maintaining relationships with the Rizzuto clan and that the Rizzuto clan is known as an Italian criminal organization ", could be read on the refusal note produced by the controller.
For two years, Mr. Oliverio, who was a member of a shooting club, objected to the controller's actions in court. During the process, counsel, M e Isabelle Mercier, including summary filed 400 pages of the Colosseum investigation by the RCMP against the Montreal Mafia in the early 2000s, with particular reference to the day of April 19, 2005.
That day, contractor Tony Magi was abducted by strangers and managed to escape. According to the summary of the investigation soon after Magi, Serafino Oliverio - aka Sergio Lopez - and an individual linked to the Mafia, Tony Volpato, met one of the lieutenants of Francesco Arcadi, Francesco Del Balso, Laennec in the bar, Laval. During this meeting, Del Balso asked Tony Magi what the individuals looked like and how he managed to remove his handcuffs.
However, Serafino Oliverio, in his petitions for the recovery of his firearms licenses, stated that the reasons for the Firearms Officer's refusal were false, unfounded and damaging to his reputation, and that the refusal was unjustified. He described himself as a respected businessman and a responsible citizen who has always been exemplary. He wrote that he always handled his weapons with care and stored them in a safe and lawful manner. He stated that he had never been the subject of a criminal charge related to his firearms, or even committed a violent act on himself or another person related to his firearms.
