Police in a California city say at least three people are dead and others are wounded after a chaotic 25-minute shooting spree.

Tustin police supervisor Dave Kanoti says there are several crime scenes as authorities work to determine if the shootings were connected. Kanoti says the shootings are believed to have started Tuesday with a fatal carjacking. As the carjacker moved into the city, police started getting reports of shots fired.

Kanoti says two victims are confirmed dead. He says the shooter then killed himself nearby.

Kanoti says it's possible there are more victims.
