PORTLAND -- The gunman in a deadly attack Tuesday afternoon at Clackamas Town Center mall has been identified as 22-year-old Jacob Tyler Roberts.

According to police, Roberts entered the mall wearing a load-bearing vest and a hockey-style mask, armed with an AR-15 semi-automatic weapon. Police are not sure how many shots Roberts fired but say they believe he was carrying several fully loaded magazines.

Multiple calls came in to police at 3:29 p.m. Tuesday of an active shooter at the mall. Police say the shooter parked his 1996 VWJetta near the entrance to the Macy's story, andentered the mall moving rapidly toward the food cart area. He shot two victims who died from their wounds.

Police say Jacobs stole the AR-15 rifle from someone known to him. It appears the suspect's rifle did jam while he was attacking victims in the food court area but he was able to get the weapon working again.

Police said they believe the shooter worked alone and there was no indication of any motive for the shooting. He had no previous criminal record.

Roberts died from a self-inflicted gunshot wound, police said.
