One person was killed and at least three others were wounded Tuesday in an active shooting near a polling place in Azusa.

Los Angeles County Sheriff’s Capt. Jeff Scroggin said police were dealing with at least one suspect who was heavily armed.

At least one of the victims was headed to the polling station to vote, a law enforcement source told The Times.

Officers arrived about 2:02 p.m. in the 300 block of North Orange Avenue to find multiple shooting victims and a man with a rifle. The gunman immediately fired at least 20 shots at police, said the source.

Under a hail of gunfire, officers took cover and returned shots at the man, who retreated into a home in the 500 block of Fourth Street, said the source, who requested anonymity because the case was ongoing. No officers were injured in the shooting.

Azusa Union School District issued a lockdown for Slauson Middle and Mountain View Elementary schools about 2:15 p.m., officials said. A nearby daycare center and preschool was also locked down.

Los Angeles County Registrar Dean Logan said the shooting was affecting two polling stations at Memorial Park, a preschool, and Dalton Elementary school.

He urged voters to avoid the area and “if necessary, cast a ballot at an alternate polling location.”

Oh, this is so bad. So very bad. My heart to the victims, and the family and loved ones of the person who was killed, for no reason at all. The word at the moment is this person is still at large. If you are in the area, please, please, do whatever you need to do to be safe. This is a bloody nightmare, and we all know who we can thank for this one.
