TUSTIN, Calif. (AP) — Authorities don't know the motive in today's rampage of carjackings and shootings across California's Orange County.
Three people were killed before the gunman ended the rampage by taking his own life.
Police say the violence began when a young man shot a woman to death in a home. Several shootings occurred in the next hour at other locations. The victim of a carjacking wasn't hurt, but an innocent bystander was hit by gunfire and taken to a hospital.
There were reports that the gunman also opened fire at other vehicles on a freeway.
Police say a pickup truck taken by the carjacker began to run out of gas, so he stopped and carjacked a BMW -- shooting and killing the driver. Another person was killed during an additional carjacking.
Police say they located the gunman and tracked him into the city of Orange. When they tried to stop him, they say, he got out of the vehicle and killed himself.

TUSTIN, Calif. (AP) — A chaotic shooting spree early Tuesday through Orange County, Calif., left four people dead, including the shooter, and two others injured before the man stopped and shot himself to death in a stolen car, police said.
There were multiple crime scenes in Tustin and Orange and many more victims who were shot at but unhurt, Tustin Lt. Paul Garaven said.
The shootings began at 4:45 a.m. when deputies responding to a call found a female shot multiple times in a house in Ladera Ranch, said Orange County sheriff's spokesman Jim Amormino. The city is in the southern part of the suburban county about 30 miles south of Los Angeles.
From 5:30 a.m. to 5:55 a.m., Tustin police received reports of shootings in several locations, Tustin police Supervisor Dave Kanoti.
The motive for the shootings was unclear, and it's also unclear if the victims knew each other or the shooter, Amormino said.
"I do not believe any of the victims are related to each other. It might have been a random thing," he said. "We just don't know."
The first call that came in was at Red Hill Avenue and Interstate 5. Police arrived and determined a carjacking had occurred and that victim was uninjured. An innocent bystander who was hit by gunfire was taken to a hospital, Garaven said.
The next call was at State Route 55 and McFadden Avenue. Another carjacking occurred and that victim died, Garaven said.
The last call was about a man with a gun, he said, at Edinger Avenue east of the 55. An officer arrived and found two more victims — one dead and the other injured.
Officers located the man and followed him into the city of Orange, Garaven said.
"When they tried to stop, he killed himself in the car," Garaven said.
The suspect is a male, although Garaven couldn't confirm his age. He didn't have the sexes of all the victims.
The lieutenant said the suspect succeeded in stealing a vehicle at each carjacking.
"There have been other people coming forward saying they were shot at or their cars were shot at," he said, but so far none had reported any serious injury.
The conditions of the wounded victims were unknown.
A spokeswoman for the California Highway Patrol said they didn't have any active crime scenes on the freeway but the southbound 55 McFadden Avenue off-ramp would be closed until further notice.
Authorities were processing six crime scenes across the county.
