Lawyer Véronique Robert said if Jonathan Massari s trial had not ended in a mistrial, he would have repudiated the prosecution s "tainted" key witness.
A Montreal man with ties to Montreal Mafia has pleaded guilty to conspiracy charges two weeks before he was set to go on trial for the murders of four men in 2016.
Jonathan Massari admitted he plotted to kill Lorenzo Giordano and Rocco Sollecito, leaders in the Rizzuto organization, and admitted to being part of the conspiracy to murder Vincenzo and Giuseppe Falduto.
