MONTREAL - The alleged head of a north Montreal street gang was one of the three men shot and killed in the city over the past 48 hours, QMI Agency has learned.

QMI Agency learned that Chenier Dupuy, 37, who was recently released from prison where he was serving time for drug offences, was shot as he was sitting in a parked car with another man in the parking lot of an east-end shopping centre Friday evening.

Police believe Dupuy is the head of Bo-Gars street gang, whose members reportedly claim allegiance to the well-known Bloods street gang that started in the U.S.

Hours later another man, who sources told QMI Agency was also a Bo-Gars member, was shot and killed outside his home just north of Montreal.

Police raided Dupuy's home in 2008 and found 900 crack rocks, 361 grams of cocaine and two kg of marijuana and hash.

Maria Mourani, a criminologist and a federal MP for the Bloc Quebecois who represents a north-end Montreal riding, said that Montrealers can expect more killings in response to the weekend's assassinations.

"Either what happened was a power struggle inside the Bo-Gars or it's an attack by their adversaries," she said.

She said the Bo-Gars are part of a larger umbrella group of gangs known as the "the Reds," that ally themselves against another group of gangs known as "the Blues."
