TUALATIN, Ore. -- "I just heard bang bang bang."
Bruce Shelby can't shake the memories. The noon air exploded Tuesday in gunfire as orders were barked inside a neighboring office.
"He said, Tony get out of here. There might have been an expletive in there, but I remember he said Tony get out of here," recalls Shelby of the shooter's voice.
63-year old lab worker Tony Ochoa crawled into the Tualatin office of Continuant Telecommunications with wounds to his chest, hand, and leg. He was able to get Shelby's attention immediately.
"I heard a voice from just inside our front door yelling call 911, call 911, call 911," says Shelby.
More shots cracked next door as 39-year old Robert Beiser attacked his estranged wife Teresa with a semi-automatic rifle, pistol grip shotgun and Colt .45 in hand.
"And then you know, bang, bang, bang, bang, bang, we heard another five or six rounds," explains Shelby. "That's when it clicked in my mind, there's somebody shooting over there."
It all happened in just seconds.
"After the first three or four shots it was obvious that he went in because I could hear his voice coming through the wall."
As Bruce and a co-worker ran for safety, Shelby's colleague Gabe Grossman attended to Ochoa's wounds.
"Boy he's got a cool head under pressure. I'm really proud of him."
When the shooting stopped, Teresa Beiser was dead in the lobby of Legacy's Metro Lab. Her estranged husband Robert was in a bathroom. He had used his shotgun to take his own life.
"It'll be eerie, It'll be hard I'm sure to get back to work," suspects Shelby.
Thursday Bruce Shelby will return to his Tualatin office to find little as it once was. The bloodstained carpet is gone, windows are covered in plywood and the trauma etched in his memory is reinforced in the destruction left behind.
