Shooting spree across Calif county leaves 4 dead

An hour later, it was over — but not before Ali Syed had killed two more people during carjackings, shot up vehicles on a busy freeway interchange and left three others injured in a trail of carnage that stretched across 25 miles.

One driver was forced from his BMW at a stop sign, marched to a curb and shot in the back of the head as other commuters watched in horror.

"He was basically executed," Santa Ana police Cpl. Anthony Bertagna said. "There were at least six witnesses."

Syed later killed himself. He lived with his parents at the Ladera Ranch residence where the first victim, an unidentified woman in her 20s, was slain, Tustin police Chief Scott Jordan said. He was unemployed, taking one class at a local community college, Jordan said.

The woman was not related to the shooter and it wasn't known what she was doing at the home, said Orange County sheriff's spokesman Jim Amormino.

Syed's parents were in the house at the time, fled the residence when shots were fired, and reported it, he said.

Jordan said Syed stated to one carjacking victim: "I don't want to hurt you. I killed somebody. Today is my last day."

Jordan said there was no indication of a motive, but he sought to assure residents that the violence was over.

"There is no conspiracy here, there are no outstanding suspects, it was a very, very unfortunate situation, but I don't think the people here in Orange County have to be worried about their safety," he said.

The violence began at 4:45 a.m., when deputies responded to a call from Ladera Ranch, a sleepy inland town about 55 miles southeast of Los Angeles. They found the woman shot multiple times.

Jason Glass, who lives across the street, said he couldn't sleep and was watching TV in his garage with the door partly open when he heard what sounded like gun shots.

Then he heard a commotion and the sound of a car speeding away.

Hours later, his neighborhood was flooded with police, and crime scene tape sectioned off the street.

"I just happened to be in here when this happened," Glass said about his garage. "To think he could have rolled under my door or needed a car or needed to hide is crazy. It's freaking me out."

From Ladera Ranch, police said the gunman headed north and pulled off Interstate 5 in Tustin, about 20 miles away, with a flat tire and other damage to his parents' car.

A man who was waiting in a shopping center parking lot to carpool with his son saw Syed had a gun and tried to escape in his Cadillac, Jordan said. Syed ran after the car as it drove away and fired his shotgun through the back window, striking the driver in head but not killing him.
