Richard Matthew Richie Chain, 31, was one of nine people killed in the May 17, 2015 Twin Peaks shooting in Waco, Texas. The violence broke out during a meeting intended to discuss political rights for motorcyclists and involved rival motorcycle clubs identified as the Bandidos and the Cossacks. Law enforcement officers were on scene to monitor the meeting when an uninvited group, presumed to be the Cossacks, arrived and gunfire erupted.

The clash left nine dead and 18 injured. Authorities arrested 177 people, most charged with participation in organized crime, but the later legal proceedings produced no convictions. Investigators have provided few firm conclusions about the exact sequence of events that led to Richie Chain’s death, in part because multiple parties were involved and the incident’s complexity hindered pinpointing individual actions.

Does anyone have information about Richie Chain’s movements that day or contacts who might help clarify what happened leading up to the shooting?
