During the conflict with the Hells Angels, he had been hired by Demers several times, and other club leaders Fred Faucher and Giovanni Cazzetta had also hired him several times between the years of 1994 and 2002. Gallant had attempted to flee to Geneva, Switzerland but was eventually arrested on credit card fraud and mistaken identity, testifying and giving more than fifty hours of statements. This enabled the authorities to apprehend Demers and ten other sponsors or accomplices of his 28 murders in 2009.

In January 2013, Demers avoided going to trial over the Gallant murders; he pleaded guilty to the lesser charge of conspiracy to commit murder and he was given 11 years in prison, with is total sentence stemming from the Quebec Biker War resulting in being 20 years, seven and a half years of provisional time were subtracted.

Cotroni was a member of the Calabrian 'Ndrangheta Cotroni crime family, who were the rivals of the Sicilian Mafia Rizzuto crime family.
