Trial is beginning in state court in Las Vegas for eight men facing felony and misdemeanor charges in a December 2008 wedding chapel brawl between Hells Angels and rival Mongols motorcycle club members. Court spokeswoman Mary Ann Price says opening statements were scheduled for Monday. A jury was picked Friday for the trial that's expected to last four weeks. Authorities say the wedding chapel melee broke out as Hells Angels leaving a wedding encountered Mongols members arriving for another wedding. Two people were stabbed and four others also suffered injuries. The eight defendants are among 13 people indicted in July 2010 on charges including attempted murder, battery, assault, conspiracy and criminal gang activity. Each has pleaded not guilty. Defense attorneys say the accused Hells Angels were acting in self-defense.
