A shooting spree through California has left four people dead, including the gunman, and several others injured.
Orange County sheriff's spokesman Jim Amormino said the shootings began in the early hours when deputies responding to a call found a female shot multiple times in a house in Ladera Ranch.
Three more people were fatally shot in the next 25 minutes after car-jackings in Tustin and Santa Ana.
Mr Amormino said the suspect shot himself at an intersection in Tustin.
The motive for the shootings is still unclear and it is also unclear if the victims knew each other or the gunman.
