More details are becoming available in shooting death in Sparks, Nevada involving the Hells Angels and a rival motorcycle gang. The shooting late Friday night at the John Asguaga's Nugget Hotel resulted in the death of a Hells Angel leader from San Jose and injuries to 2 rival Vagos gang members. The gang members were among thousands of attendees at the annual Sparks "street vibrations" event. Concern about retaliation led local and state officials to declare a to a state of emergency, which was eventually lifted around 5 p.m. on Saturday. A Sacramento gang detective investigating the case in Nevada said one of the gang members shot at in retaliation is from Sacramento. That gang member was shot twice in the chest Saturday morning. He was expected to survive. In response to concerns about retaliation, a Sacramento ATF agent said, "We always try to be aware of crimes of violence in our community. We try to anticipate when and where there will be violations of the federal firearm and explosive laws. We are watching this very closely," said Graham Barlowe, ATF Sacramento's Resident Agent in Charge.
