One theory out there mentioned in the LaPresse news,was that the shooting was due to an internal purge going on within the Hells Angels.
I have a theory of my own. Vincent Lamer was shot on November 3,2017 and Jacques Desjardins the brother of Raynald went missing around the same time. Vincent Lamer was a close confident of Maurice "mom" Boucher. Mom Boucher was caught in the Magot Mastiff for plotting to murder Raynald Desjardins. I am just wondering if a feud is going on between Mom and Raynald. Time will tell.
