Update, 7:10 p.m. Tuesday: AZUSA — Authorities say a gunman is dead after killing a man and critically wounding two women not far from two polling places that were closed as a result.
They say the assault rifle attack in the Los Angeles suburb of Azusa wasn't election-related.
The two polling sites were shut down for several hours Tuesday while officers surrounded a home where the gunman's body was found. One later reopened.
Authorities called to the scene got into a gunbattle and police say it's unclear whether they fatally wounded the gunman or he killed himself. No officers were hurt.
The shooting took place not far from several schools, including one that was serving as a polling place, and across the street from a park that also had a polling site.
Police don't have a specific motive for the shootings.
The names of the gunman and the dead man haven't been released. The wounded victims are described as two women in their mid-50s.
Update, 6:20 p.m. Tuesday: Someone with an assault rifle killed one person and wounded two others Tuesday near two Los Angeles-area polling sites that were locked down as a result.
The suspect then began shooting at arriving officers who returned fire before they took cover near a park, Azusa Police Chief Steve Hunt said.
One person was down at the front door of a home but Hunt couldn't immediately say whether that person was the shooter.
Police Officer Jerry Willison said the person was believed to be dead.
Elections officials say one of the polling sites later reopened. Voters were being urged to seek nearby polling places. The motive of the shooting was unknown and it was unclear if it had anything to do with the election.
"It's still too early to tell," Hunt said. "It appears to be concentrated on the residential side, not the polling station."
No officers were hurt.
Hunt said police were looking for a female suspect. He did not know if she had been wounded or killed in the exchange of gunfire with police.
Witnesses described the shooter as a man, and police could not immediately clear up the confusion.
