 Lavoie had previously been buying his wares from the Pelletier Clan associated with the Rock Machine, but had recently switched to the Hells Angels, and as a result the Pelletier Clan hired a criminal named Patrick Call to kill Lavoie.On 28 October 1994, Sylvain Pelletier, the leader of the Pelletier Clan, was killed by the Hells Angels, who threatened to murder any drug dealer who did not buy their supplies from them.After these killings, an increasingly murderous struggle for the control of the drug trade in Montreal began between the Hells Angels and the Rock Machine that would not end until 2002.
