Hells Angel Leader
San Francisco police are investigating the slaying of a Hells Angels leader in the city.
Mark "Papa" Guardado, 45, the president of the motorcycle club's San Francisco chapter, was shot Tuesday night about a mile from the group's clubhouse. Guardado died at San Francisco General Hospital.
Police think Guardado may have been in fight with a rival in another motorcycle group before he was killed. Witnesses told investigators that he and the gunman struggled before the shooting and that the suspect fled on a motorcycle.
The San Francisco chapter is one of the oldest Hells Angels branches in the country. The half-centry-old club is known for an outlaw image, and its members have been a target of police anti-gang and anti-drug efforts.
