A jury is now deliberating the case of a man accused of committing murder under the command of the Hells Angels.
Paul Fontaine is charged with first degree murder for the 1997 killing of prison guard Pierre Rondeau. The guard was killed during an ambush of a prison bus in the east end of Montreal.
The principal witness in the case, Stephane "Godasse" Gagne, was also involved in the crime, making it a difficult deliberation for the jury.
Gagne pleaded guilty to charge of murder related to the death of Diane Lavigne, a prison security guard who was killed a few weeks earlier than Rondeau. He was able to plea bargin out of the charges for the murder of Rondeau.
Initially it was believed the killing of the guards was intended to destabilize the justice system. However, it was revealed in court that the killings were also ordered to test the loyalty of Fontaine, Gagne and others.
The jury has been sequestered since Tuesday evening.
