Sony Barger Cause of Death

The leather-clad figurehead of the notorious Hells Angels motorcycle club, Sony Barger, has died. He was 83. His death was announced on Wednesday on a Facebook page.

According to reports he died of cancer.

He was a founding member of the Oakland, California, chapter of the Hells Angels in 1957 and was at present at its most infamous moment-the 1969 Rolling Stones concert at Altamont Speedway during which bikers were hired as security staff fatally stabbed concertgoers who pulled a gun on one of the members.

The Hell Angels were typically depicted by the media as a dark fringe of the 1960s counterculture, embracing freedom, drugs and rock music, but also crime and violence.
