UPDATE 7:20 p.m.: (AP) - Authorities in California 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 gun battle 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.
