Mark "Papa" Guardado president of the San Francisco branch Hell's was found about 10:30 p.m. with gunshot wounds at 24th Street and Treat Avenue

Mark "Papa" Guardado, 45, was found about 10:30 p.m. with gunshot wounds at 24th Street and Treat Avenue, about a mile from the group's clubhouse. He died a short time later 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. At the time of his death, Guardado was the subject of an ongoing investigation into an assault with a deadly weapon incident, said Sgt. Jim Stephenson of the Petaluma Police Department. "He beat up a random guy at a bar," said Stephenson. "He beat him with his hands and feet."When police responded to the Petaluma bar, officers said Guardado volunteered the fact that he was president of the San Francisco branch of the notorious motorcycle gang.
"He told us he was president, plus it was on his jacket," said Stephenson, who also told CBS 5 that Petaluma police kept the jacket as evidence in the case.
Guardado filed suit in May against Sonoma County Sheriff's deputies who refused to let him and a co-defendant wear their Hell's Angels insignia in court. A judge later backed up the Sheriff's Department and disallowed the two defendants from wearing the insignia.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.
