On the night of July 11, 2020, a violent clash between rival motorcycle clubs near Jake’s Roadhouse BBQ on North Lamar Street in Arvada, Colorado, left 43-year-old William Kelly Henderson dead from a gunshot wound. The confrontation between members of the Hells Angels and the Mongols also wounded two other men by gunfire and produced further brutality when a local musician who tried to help Henderson was struck with a helmet and run over by a motorcycle, suffering a traumatic brain injury and other severe long-term injuries.

The suspects fled the scene, and investigators say fleeing assailants also ran two other motorcyclists off the road, causing serious harm. A 19-month, multiagency investigation involving the Arvada Police Department and the ATF led to arrests of ten men across Colorado, California, Utah and Florida on charges that included first-degree murder, attempted first-degree murder and violations of Colorado’s Organized Crime Control Act. Nine of the ten pleaded guilty and were sentenced in Jefferson County District Court in April 2024; prosecutors said they could not definitively identify who fired the shot that killed Henderson but pursued racketeering and related charges against Mongols members.
