In California, one person was left dead and two others wounded after a man high on cocaine and armed with handguns, a rifle and shotgun opened fire near a polling station in the city of Azusa, east of Los Angeles. Police Chief Steve Hunt said the gunman was found dead after a battle with police.

Steve Hunt: “We believe that the suspect was armed with an assault rifle with a rapid-fire capability. Whether it’s fully automatic or semiautomatic, we don’t know at this time.”

The violence halted voting at two polling places and caused a lockdown at a nearby middle school. Police say the gunman fired at least 20 rounds at officers. The shooting came mere hours before California voters approved Proposition 63, which bans possession of magazines that hold more than 10 rounds, and provides a process for felons to have guns confiscated.
