Wayne Lee Sidetrack Campbell, 43, was killed on May 17, 2015, in Waco, Texas, during the deadly shootout at the Twin Peaks restaurant. A member of the Cossacks Motorcycle Club and serving as one of the club’s road captains, Campbell died of gunshot wounds to the head and trunk. He was from Arlington, Texas.

The brawl involved rival clubs the Bandidos and the Cossacks and left nine dead and 18 wounded after an argument escalated into gunfire. Law enforcement officers who were monitoring the meeting responded to the shooting. In the immediate aftermath more than 170 people were arrested and charged with engaging in organized criminal activity; the investigation continued for years but ultimately produced no convictions.

Campbell’s death was part of a long-running feud between the Bandidos and the Cossacks that included earlier skirmishes and killings. Friends and family left tributes on his Facebook page. Does anyone have information about Campbell, that day at Twin Peaks, or the events leading up to the shootout?
