Daniel Raymond Danny Diesel, 44, was killed on May 17, 2015, in Waco, Texas, during the violent shootout at the Twin Peaks restaurant that left nine men dead. He was a regional road captain for the Cossacks Motorcycle Club and died of gunshot wounds to the head. The clash began as an argument between bikers and escalated into a broader confrontation; police were already in the area beforehand because of concerns about potential violence and officers opened fire during the incident. Reports state that at least four of the victims, including Diesel, were killed by police gunfire.

In the aftermath more than 170 people were arrested and charged with engaging in organized criminal activity and held on $1 million bail each while the investigation continued. Diesel is described as a well respected member of his community and his club, known for organizing rides and looking after fellow members. The full sequence of events and individual responsibilities remain under investigation.
