The man who killed two people and seriously wounded a third in a crowded Oregon mall Tuesday was identified Wednesday, the Associated Press reports.

Shortly before 3:30 p.m. Tuesday, Jacob Tyler Roberts, 22, walked into a Portland mall carrying a long AR-15 semi-automatic rifle, according to police reports. As Christmas music played in the background, Roberts entered the mall's food court and opened fire on shoppers, letting off an estimated 60 shots before turning the gun on himself, the county sheriff said.

Roberts' victims, who authorities claim had no connection to the shooter, were 54-year-old Cindy Ann Yuille and 45-year-old Steven Mathew Forsyth. A third victim, 15-year-old Kristina Shevchenko, was shot through the chest, but survived the attack. She is in serious condition at a local hospital.

"It did not appear as though he was targeting any specific individual, it really looked as though it was a random shooting," Clackamas County Sheriff Craig Roberts told NBC News. "It was very apparent that he had a mission set forth to really take the lives of people within that mall."

Witness say they saw the shooter wearing camouflage and a white hockey mask as he walked through a Macy's store in the mall. Austin Patty, 20, who works at the Macy's, said he heard the gunman announce "I am the shooter" before letting off a series of rapid-fire shots. Another witness, 16-year-old Alina Pavlenko, told The Oregonian that the gunman was "walking so slow" and that, after dropping ammo he "just slowly picked it up and put it back in" and continued to shoot. The mall's Santa Claus, Brance Wilson, was busy fielding Christmas wishes from children when he heard the shots ring out.

"I heard a couple of shots that sounded like shots, and at the time, I didn't think too much about it," Wilson told the AP. "But then when I heard about 18 more shots, I decided it was a semi-automatic and hit the floor."

The first 911 call came in at 3:30 p.m. Tuesday, Sheriff Roberts said. A response team from several different law enforcement agencies responded within minutes, and by 3:51 p.m., the mall had been cleared, with the victims and gunman found.

Roberts said the shooter is believed to have been wearing a "load-bearing vest" and using a rifle stolen from a friend.
