William Waterhead Allen, 22, was one of five Outlaws Motorcycle Club members and a visiting friend killed in a mass shooting at the Outlaws clubhouse on Allen Road in Charlotte, North Carolina, on July 4, 1979. Allen was on guard duty and was found dead on the front porch with multiple gunshot wounds to the chest by club leader William Kincaid Chains Flamont. Police reports say two suspects fired about 40 rounds with a 9mm and a .223 semiautomatic during the attack.

The massacre was believed to have been carried out by members of the rival Hell’s Angels amid high tensions between the groups. Investigators later identified Gregory Scott Lindaman and Randy Allen Pigg as suspects, but they were never charged for lack of evidence. Lindaman died in a car accident in 1990 and Pigg died of liver failure in 2007; the Charlotte-Mecklenburg Police Department administratively cleared the case by Death of Offender in 2015. The killings prompted hundreds of Outlaws to attend the funerals and remain a prominent, unsolved chapter in Charlotte’s history.
