PORTLAND, Oregon A gunman opened fire in a suburban Portland shopping mall Tuesday, killing two people and wounding another before apparently killing himself as people were doing their Christmas shopping, authorities said. One other person was reported injured.

Clackamas County sheriff's Lt. James Rhodes said authorities were still trying to get more details about the situation at the Clackamas Town Center. So far, the shooter has only been described as an "adult male."

Authorities said there was no indication that there was more than one gunman. Officials say police did not fire a shot during the incident.

"At first no one really knew what was going down," Mario, a kiosk worker inside the mall, told CBS affiliate KOIN in Portland. "We heard six shots at first, and then people scattered like crazy, everybody left."

"The shots were really loud and really scary... It was echoing all through the mall, so nobody knew where it was coming from at first," witness Larisa Tereahova said.

Another witness said the Macy's inside the mall 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.

Macy's employees Pam Moore and Austin Patty told the AP the shooter was short, with dark hair, dressed in camouflage. He had body armor and a rifle and was wearing a white mask, they said.

"I heard about 20 shots and everyone hit the ground," Moore said. "That's when we all just ran."

Governor John Kitzhaber released a statement late Tuesday, saying: "My thoughts and prayers are with the victims and their families. I appreciate the work of the first responders and their quick reaction to this tragic shooting. Oregon State Police Superintendent Rich Evans is on the scene. I have directed State Police to make any and all necessary resources available to local law enforcement."
