Dec. 11, 2012— -- A masked gunman opened fire today at Clackamas Town Center, a mall in suburban Portland, Ore., killing two people, injuring one, and then killing himself.
"I can confirm the shooter is dead of an apparent self inflicted gunshot wound," Lt. James Rhodes of the Clackamas County, Ore., Sheriff's Department said today. "By all accounts there were no rounds fired by law enforcement today in the mall."
Police have not released the names of the deceased. Rhodes said authorities are in the process of notifying victims' families. The injured victim has been transported to a local hospital.
Rhodes described the shooter as an adult male.
Witnesses from the shooting rampage said that a young man in a white hockey mask and bulletproof vest tore through the Macy's, food court, and mall hallways firing rounds at shoppers beginning around 3:30 p.m. PT today.
Hundreds of people were evacuated from the busy mall full of holiday shoppers after the shooting began.
The gunman entered the mall through a Macy's store, ran through the upper level of Macy's and opened fire near the mall food court, firing multiple shots, one right after another, with what is believed to be a black, semiautomatic rifle, according to witness reports.
Amber Tate said she was in the parking lot of the mall when she saw the shooter run by, wearing a mask and carrying a machine gun, headed for the Macy's.
"He looked like a teenager wearing a gun, like a bullet-proof vest and he had a machine, like an assault rifle and a white mask and he looked at me," she said.
Witnesses described the shooter as being on a mission and determined, looking straight ahead. He then seemed to walk through the mall toward the other end of the building, shooting along the way, according to witness reports.
Those interviewed said that Macy's shoppers and store employees huddled in a dressing room to avoid being found.
"I was helping a customer in the middle of the store, her and her granddaughter and while we were looking at sweatshirts we heard five to seven shots from a machine gun fire just outside my store," Jacob Rogers, a store clerk, told ABC affiliate KATU-TV in Portland.
"We moved everyone into the back room where there's no access to outside but where there's a camera so we can monitor what's going on out front," Rogers said.
Evan Walters, an employee at a store in the mall, told ABC News Radio that he was locked in a store for his safety and he saw two people shot and heard multiple gunshots.
"It was over 20, and it was kind of surreal because we hear pops and loud noises," he said. "We're next to the food court here and we hear pops and loud noises all the time, but we don't -- nothing like that. It was very definite gunshots."
Police are tracing the weapon used in the shooting.
