Richard Vincent Rick Kirschner, 47, was one of nine men killed in the violent shootout at the Twin Peaks restaurant in Waco, Texas, on May 17, 2015. Kirschner, a member of the Cossacks Motorcycle Club known as Bear, died of gunshot wounds; an autopsy found he was shot three times and toxicology detected traces of cocaine and alcohol.

The confrontation began as an argument between rival motorcycle clubs, primarily the Bandidos and the Cossacks, and rapidly escalated into a gunfight. Police who were already in the area fired shots as they responded; in all nine bikers were killed and 18 others were injured. More than 170 people were arrested and charged with engaging in organized criminal activity, bail set at $1 million each. The investigation into the incident remains ongoing.

Did anyone who knew Kirschner or who was at Twin Peaks that day come forward with details that might clarify what ignited the violence?
