How did chaos unfold at Safeway in Bend?

A man began firing shots in the parking lot of the Forum Shopping Center, in northeast Bend, around 7 p.m. Sunday, police said in a statement. The man entered Safeway’s west entrance and shot one person, who died on the way to the hospital. The shooter continued firing through the store, shooting and killing another victim.

A third person who was shot was taken to the hospital and is in good condition, said Lisa Goodman, spokesperson for St. Charles Bend hospital.

Josh Caba told local TV station KTVZ that he was with his four children when he heard multiple shots as he shopped. 

“I immediately turned to my children and said, ‘Run!’ People were screaming,” Caba told the news outlet. “It was a horrifying experience.”

Molly Taroli, 40, told local newspaper The Bulletin that she and her husband were shopping for dinner when the shooter sprayed shots through the store. Taroli said she took her own handgun from her purse, and that employees yelled “go, go, go!” as they tried to help people escape,  Taroli told The Bulletin.

Bend Police chief Mike Krantz said police immediately entered Safeway as shots were being fired. Police not fire their weapons at the scene, he said.

Krantz described the crime scene as "very large," spanning from the residential area behind the shopping center to the center's parking lot.

Nearby surveillance video showed the suspect leaving a motel room and shooting at random, the statement said. The shooter was seen firing into the motel before shooting into a car coming into the parking lot.

He fired shots at police arriving at the scene, authorities said. Surveillance footage showed him falling to the ground, and police say it appeared the suspect may have taken his own life.
