SEATTLE (AP) — Seattle police say Seattle Pacific University staffers disarmed a lone gunman who entered a building, shot four people and started to reload. A hospital spokeswoman says one man has died and three other people are injured, one critically.

Police say the gunman is under arrest and the Otto Miller building — where the Thursday afternoon shooting took place — has been secured.

Harborview Medical Center spokeswoman Susan Gregg says a man in his 20s has died and a critically injured 20-year-old woman has been taken to surgery. Gregg says a 24-year-old man and a 22-year-old man are in satisfactory condition.

Gregg says the hospital is not expecting any more injured people from the shooting.

About 4,270 students attend the private Christian university, located in a residential neighborhood about 10 minutes from downtown Seattle.
