Motorcycle Club Gun Battle: Calif. biker's club gun violence kills 1, wounds 12 people

(CBS/AP) FRESNO - A "running gun battle" at a Central California motorcycle club's annual dance left one man dead, a dozen others wounded, hundreds of partygoers scrambling for cover and now, investigators are trying to determine what triggered it.

As the first of more than 100 law enforcement officers arrived early Saturday morning, shots were still being fired around the Soul Brothers clubhouse near Fresno, the Fresno County Sheriff's Office said.

The gunfire erupted during the Soul Brothers' annual dance, which draws bikers and other motorcycle clubs from all over the state. About 500 people were inside the warehouse-like clubhouse when the shooting started.

The shooting began inside, then quickly moved outside, where a gun battle ensued, reports CBS Fresno affiliate KGPE-TV.

The shooting quickly turned into "a running gun battle" in the street, and hundreds of partygoers were running for cover when the first officers arrived, sheriff's spokesman Chris Curtice said.

Residents in the area described being awakened by the sound of gunshots and roaring motorcycles.

"Me and my son were out here and, all of a sudden, we heard some yelling, and then we heard shooting," one nearby resident told the station.

Despite briefly detaining and questioning about 100 people, authorities have yet to make an arrest.

The Fresno County coroner identified the dead man Sunday as Dejuan Gladney, 18. The coroner didn't list a hometown.

Gladney and several injured people were found in the clubhouse, which is in an unincorporated neighborhood of Fresno County called Calwa. Another victim was on a nearby street.

Curtice said the injuries ranged from minor to "extremely serious." Authorities have not released the names of the people who were wounded.

Large gatherings of bikers descend on Fresno twice a year, once in the spring and then again in fall, the Fresno Bee reported. The gatherings frequently turn violent, the newspaper said, but police blame gangs for starting some of the violence rather than the bikers themselves.

The club's website was inoperable Sunday and no representative could be reached at the clubhouse. The Facebook page for the club billed the event, which began late Friday, as the "Kings of Cali Party."

Old newspaper reports say Soul Brothers was formed in 1967 in East Palo Alto as a multi-racial club before moving to Stockton and then Fresno. The club also has a Las Vegas chapter, whose phone rang unanswered Sunday.

Some residents are calling for the clubhouse to be closed in light of the latest violence, says KGPE.
