The shooting occurred around 2 p.m. local time. Police told the Times that law enforcement were dealing with at least one heavily armed female suspect. Several witnesses, however, told the paper that the shooter was a man.
Azusa Police Chief Steve Hunt noted that it was too early to speculate on a motive for the shooting, but did say that it seemed to focus on a residential area.
“It’s very early to tell what the motive is, but it appears to be concentrated on the residential side, not at the polling station,” Hunt told the paper.
Police urged those in the area to stay indoors, telling the paper that the suspect had barricaded themselves in a home.
The shooting was near the site of two local polling stations which temporarily closed, according to a local elections official. One opened up again shortly afterwards.
