The fatal shooting of LeClair was part of a gang war between the U.N. Gang and their rivals, the Bacon brothers and the Red Scorpions.

LeClair was said to be a member of the rival Red Scorpions gang, which was involved in a bloody turf war in 2008 and 2009, considered to be some of the worst gang violence in the history of the Lower Mainland.

Vallee, 34 at the time of LeClair91ÂãÁÄÊÓƵ™s murder, had been hired as an assassin by the UN Gang, which had targeted Jonathan, Jamie, and Jarrod Bacon 91ÂãÁÄÊÓƵ“ the Bacon Brothers 91ÂãÁÄÊÓƵ“ and their allies and associates in the Red Scorpions Gang, including LeClair.

On the day of LeClair91ÂãÁÄÊÓƵ™s killing, Vallee stalked his victim all day and waited for him outside a restaurant in a Walnut Grove shopping plaza.

Vallee gunned down LeClair with an AR-15 in a hail of bullets in the parking lot as pedestrians ducked for cover and fled the scene.

Following the killing of LeClair, Vallee was charged with an unrelated crime in Alberta. He fled the country while released on bail and hid out in Mexico until 2014, when he was extradited to face the murder charge.
