PORTLAND, Ore. (AP) -- 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, authorities said Wednesday.
Jacob Tyler Roberts had armed himself with an AR-15 semiautomatic rifle and had several fully loaded magazines when he arrived at a Portland mall on Tuesday, said Clackamas County Sheriff Craig Roberts.
The sheriff said the rifle jammed during the 22-year-old's attack, but he managed to get it working again. He later shot himself. Authorities don't yet have a motive but don't believe he was targeting specific people.
Two people -- a 54-year-old woman and a 45-year-old man -- were killed, and another, Kristina Shevchenko, 15, was wounded and in serious condition on Wednesday.
Roberts, wearing a hockey-style face mask, parked his 1996 green Volkswagen Jetta in front of the second-floor entrance to Macy's and walked briskly through the store, into the mall and began firing randomly, police said.
He fatally shot Steven Mathew Forsyth of West Linn and Cindy Ann Yuille of Portland, the sheriff said.
Roberts then fled along a mall corridor and into a back hallway, down stairs and into a corner where police found him dead from an apparent self-inflicted gunshot, authorities said.
People at the mall were heroic in helping get shoppers out of the building, including medical personnel who rendered aid, Roberts said.
In response to previous mass shootings elsewhere, the first arriving officers were trained to form teams and go inside instead of waiting for SWAT. Employees at the mall also received training to handle such a situation.
"This could have been much, much worse," Roberts said.
The first 911 call came at 3:29 p.m. Tuesday and officers arrived a minute later. By 3:51 p.m., all the victims and the gunman and rifle had been found. Four SWAT teams spent hours clearing the 1.4 million square-foot mall, leaving shoppers and workers to hide in fear.
Roberts rented a basement room in a modest, single-story Portland home and hadn't lived there long, said a neighbor, Bobbi Bates. Bates said she saw Roberts leave at 1:30 p.m. Tuesday wearing a dark jacket and jeans, carrying a guitar case. An occupant at the house declined to comment.
The mall Santa, Brance Wilson, was waiting for the next child's Christmas wish when shots rang out, causing the mall to erupt into chaos.
About to invite a child to hop onto his lap, Wilson instead dove for the floor and kept his head down as he heard shots being fired upstairs in the mall.
"I heard two shots and got out of the chair. I thought a red suit was a pretty good target," said Wilson, 68. Families waiting for Santa scattered. More shots followed, and Wilson crept away for better cover.
Witnesses heard the gunman saying, "I am the shooter," as he fired rounds from a semi-automatic rifle inside the Clackamas Town Center, a popular suburban mall several miles from downtown Portland.
Some were close enough to the shooter to feel the percussion of his gun.
Kayla Sprint, 18, was interviewing for a job at a clothing store when she heard shots.
"We heard people running back here screaming, yelling '911,'" she told The Associated Press.
Sprint barricaded herself in the store's back room until the coast was clear.
Jason DeCosta, a manager of a window-tinting company that has a display on the mall's ground floor, said when he arrived to relieve his co-worker, he heard shots ring out upstairs.
DeCosta ran up an escalator, past people who had dropped for cover and glass littering the floor.
"I figure if he's shooting a gun, he's gonna run out of bullets," DeCosta said, "and I'm gonna take him."
DeCosta said when he got to the food court, "I saw a gentleman face down, obviously shot in the head."
"A lot of blood," DeCosta said. "You could tell there was nothing you could do for him."
He said he also saw a woman on the floor who had been shot in the chest.
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. There was a series of rapid-fire shots in short succession as Christmas music played. Patty said he dove for the floor and then ran.
His Macy's co-worker, Pam Moore, told the AP the gunman was short, with dark hair.
Kira Rowland told KGW-TV that she was shopping at Macy's with her infant son when the shots started.
