The city of Sparks, Nev., declared a state of emergency Saturday after a Hells Angels chapter president died in a casino shootout with a rival biker gang. Mayor Geno Martini also canceled the Street Vibrations biker festival that was under way in the city, which is located adjacent to Reno where an annual air show was canceled when a plane crashed into the grandstand earlier this month. The announcement came after the man killed in the Friday night shooting at John Ascuaga's Nugget casino was identified as Jeffrey Pettigrew, president of the San Jose, Calif., chapter of the Hells Angels. The gunfire also left two members of the rival Vagos in stable condition at an area hospital and landed another Hells Angel in jail on a charge assault with a deadly weapon. Police said in a written statement that another biker, who was not identified, was shot at a traffic light at 10:40 a.m. Saturday by a gunman driving a BMW sedan. Although the two incidents could not be definitively linked, the city decided it was time to clamp down in the situation. Along with the cancellation of the biker festival, police beefed up patrols in the downtown area.
