Shootout at Oregon Office Park

At least two have been reported dead in a Portland-area workplace shooting Tuesday, MSNBC reports. The gunman fired shots at Tualatin, Oregon, drug-testing center Legacy Metro Lab, where local police say two died and several were injured. The suspected shooter is "not at large" and is believed to have acted alone. Witnesses told The Oregonian that they heard between five and eight gunshots; one man described seeing a woman in a blood-smeared lab coat fleeing the scene, then helping her tend to her wounds at a nearby Subway restaurant.
