Police say the gunman who killed two people and himself in a shooting rampage at an Oregon mall was 22 years old and used a stolen rifle from someone he knew.
Clackamas County Sheriff Craig Roberts says that Jacob Tyler Roberts had armed himself with an AR-15 semiautomatic rifle and had several fully loaded magazines.
Roberts says the rifle jammed during the 22-year-old's attack, but he managed to get it working again.
The chief says authorities don't yet have a motive.
A law enforcement official has told The Associated Press the shooter did not have a criminal record. The official spoke on condition of anonymity because he was not authorized to discuss details of an ongoing criminal investigation.
Two people were killed, and another was wounded.
PORTLAND, Ore. (AP) — A gunman opened fire in a suburban Portland shopping mall Tuesday, killing two people and wounding another as people were doing their Christmas shopping, authorities said.
Witnesses described a scene of chaos and disbelief as a gunman wearing some sort of camouflage outfit and a white mask shot an initial burst of fire and then more rounds at Clackamas Town Center. Shoppers tried to find safe areas as teams of police officers began entering the mall to find the shooter.
Clackamas County sheriff's Lt. James Rhodes said later that the gunman was dead, but he wouldn't say how he died or provide any details about him.
Authorities were going store-to-store to secure the scene and to escort hiding shoppers outside, but Rhodes said there was no indication that there was more than one shooter.
Austin Patty, 20, who works at Macy's, said he saw a man in a white mask carrying a rifle and wearing a bulletproof vest.
He heard the gunman say "I am the shooter," as if announcing himself, Patty said. He then fired several shots paced seconds apart.
A series of rapid-fire shots in short succession followed. Patty said he ducked to the ground, then ran.
His Macy's co-worker, Pam Moore, told The Associated Press the gunman was short, with dark hair, dressed in camouflage. He had body armor and a rifle.
"I heard about 20 shots and everyone hit the ground," Moore said. "That's when we all just ran."
Shaun Wik, 20, from Fairview, said he was Christmas shopping with his girlfriend and opened a fortune cookie at the food court. Inside was written "live for today, remember yesterday, think of tomorrow."
As he read it, he heard three shots. He heard a man he believes was the gunman shout, "Get down!" but Wik and his girlfriend ran. He heard seven or eight more shots. He didn't turn around.
"If I had looked back, I might not be standing here," Wik said. "I might have been one of the ones who got hit."
Kira Rowland told KGW-TV that she was shopping at Macy's with her infant son when the shots started.
"All of a sudden you hear two shots, which sounded like balloons popping," Rowland told the station. "Everybody got on the ground. I grabbed the baby from the stroller and got on the ground."
Rowland said she heard people screaming and crying.
"I put the baby back in the stroller and ran like hell," Rowland said. "It was awful. It was shots after shots after shots like a massacre.
"It was just awful."
Holli Bautista, 28, said she was shopping in the Macy's for a Christmas dress for her daughter when she heard a two or three pops that sounded like firecrackers.
"I heard people running and screaming and saying 'Get out, there's somebody shooting,'" she told the AP. "It was a scene of chaos."
She said hundreds of shoppers and mall employees started running, and she and dozens of other people were trying to escape through an exit in the department store.
Bautista said the Macy's opens into the food court area, where it was reported the shootings took place. Bautista said it sounded like the shots were coming from that direction.
Tiffany Turgetto and her husband of Gladstone had exited Macy's through the first floor when they heard the gunshots coming from the second floor of the mall.
"People in front of us people were dropping, finding covering," she told the AP. "People were yelling screaming and gasping, yelling to get out. The lady next to us, she threw a chair and started running. We couldn't run because the chair was there."
Turgetto and her husband and other people were able to quickly leave through a Barnes & Noble bookstore before the police arrived and locked down the mall.
"I had left my phone at home. I was telling people to call 911. Surprisingly, people are around me, no one was calling 911. I think people were in shock."
