WACO - Police have confirmed nine motorcycle gang members are dead as a result of a shooting between rival biker gangs in the parking lot outside Twin Peaks located in the Central Texas Marketplace in Waco. Police on scene confirm the shooting started about 12:15 p.m. Sunday afternoon and involved at least two biker gangs. The shooting reportedly started after an argument inside Twin Peaks escalated to the parking lot. Police say restaurant management had been aware that the gangs frequented their restaurant. There were nine fatalities and multiple injuries reported, but no word yet on the exact number of those injured or their condition. A witness on scene said she saw at least two bodies under sheets. "In 34 years of law enforcement, this is the most violent crime scene I have ever been involved in," Swanton said.
