TUSTIN, Calif. (AP) — Authorities have identified a woman who was shot to death in a home in southern Orange County by a gunman who went on to kill two more people and injure at least three others in an hour-long shooting spree, a sheriff's spokesman said Wednesday.
The woman's name and 911 calls of the incident were expected to be released later in the day pending the notification of the woman's family, said Jim Amormino, of the Orange County sheriff's office.
The woman, in her 20s, was the first of three people killed by 20-year-old part-time community college student Ali Syed in a rampage that began before dawn Tuesday and ended 25 miles to the north during the early morning rush hour, police said.
Syed killed two more people during carjackings, injured at least three more and shot up cars zooming down a busy freeway interchange before committing suicide with his shotgun as police closed in.
The shooter forced one commuter stopped at a stop sign out of his BMW, marched him to a curb and shot him three times from behind shocked witnesses looked on, said Tustin police Chief Scott Jordan.
The motive for the shootings remained unclear Wednesday. Syed had no criminal history and no history of mental illness or mental disability, said Lt. Paul Garaven, a Tustin police spokesman. An autopsy will determine whether Syed had any drugs in his system, said Gail Krause, a sheriff's spokeswoman.
His parents did not recognize the woman who was shot to death in the Ladera Ranch home they shared with their son, she said.
They rushed outside and called police at 4:45 a.m. Tuesday after hearing the gunshots, but Syed had already sped off in his parents' black SUV.
"We still don't have an update as to the relationship between any of the victims and suspect. That's something we're still working on," Garaven said Wednesday. "There may be some nexus between somebody involved or it could have been totally random."
From Ladera Ranch, the gunman headed north and pulled off Interstate 5 in Tustin, about 20 miles away, with a flat tire, police said.
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.
The driver "noticed that he was loading his shotgun, so he simply gets back in his car and tries to escape," Jordan said. "He's driving through the parking lot trying to get away and the suspect is actually chasing him on foot, taking shots at him."
Syed then crossed the street to a Mobil gas station, where he approached the driver of a pickup who was filling his tank and asked for his keys, Jordan said.
"He says something to the effect of, 'I've killed somebody. Today's my last day. I don't want to hurt you. Give me your keys,'" the police chief said. "He hands over the keys and he gets in the truck and leaves."
Syed got back on the freeway, where he pulled to the side of the road at the busy I-5 and State Route 55 interchange and began firing at commuters, Jordan said.
One driver was struck in the mouth and hand. He didn't have a cellphone, but was able to drive home and call police. Two other cars were hit but their drivers weren't injured, Jordan said.
"All of this is happening so quickly," he said, estimating that Syed shot at drivers from the side of the freeway transition for about a minute.
The shooter then exited the freeway in nearby Santa Ana but ran the curb and got his car stuck, authorities said.
He approached Melvin Lee Edwards, of Laguna Hills, who was on his way to his family-owned gear manufacturing business in Santa Ana.
Syed shot Edwards three times, including in the back of the head and the back, Jordan said.
Onlookers "tried to get away. They saw what was going on, they tried to get away and they called police," he said.
A brief biography on Rubicon Gear's website said the 69-year-old was served as a U.S. Army combat infantry officer in Vietnam and graduated from the University of Southern California.
A woman who answered the phone at Edwards' address late Tuesday declined to comment and calls to the business were not returned Wednesday.
Syed took Edwards' BMW and next popped up at the Micro Center, a Tustin business, where he shot and killed construction worker Jeremy Lewis, 26, of Fullerton. Lewis' co-worker rushed to intervene and was shot in the arm, Jordan said.
Syed took the second construction worker's utility truck and fled to Orange, this time with California Highway Patrol officers in pursuit. He jumped from the moving utility truck at an intersection in Orange, about five miles away, and shot himself in the head, Jordan said.
"There really wasn't a confrontation at the very end," he said. "It happened so quickly."
A shotgun was recovered at the scene and is believed to be the only weapon used.
A message left for Syed's parents was not returned.
