A shooting in Southern California has killed one person and wounded three others near a polling site.

Los Angeles County Fire Inspector Gustavo Medina says one person was dead on arrival in the city of Azusa on Tuesday. He says two people were airlifted to hospitals and a fourth was being treated.

An elementary school that's also a polling place was on lockdown. Elections officials say one other polling site was affected, urging voters to cast their ballots in other locations.

The motivation is unknown and it's unclear whether the shooting has anything to do with the election.

Azusa police say arriving officers found multiple victims, came under fire and returned fire themselves. No officers were injured, and no arrests have been made.
