A woman was killed and two of her co-workers were injured when the woman's estranged husband opened fire Tuesday at a drug-testing laboratory in suburban Portland before turning the gun on himself, police said.

The woman who was killed was identified as Teresa Marie Beiser, 36, of Gladstone. Her husband, Robert James Beiser, 39, died of a self-inflicted gunshot wound, police said.

Teresa Beiser worked at the Legacy MetroLab in an office park across from a strip mall in Tualatin, about 13 miles south of Portland.

The names of her injured co-workers were not released, but authorities said they were a 20-year-old woman and 63-year-old man.

The 63-year-old man was flown to Oregon Health & Science University hospital in Portland, where he was being treated for multiple gunshot wounds, Tualatin Police Chief Kent Barker said.

The 20-year-old woman was taken by ambulance to Legacy Emanuel Hospital in Portland, where she was treated for non-life-threatening injuries. It was not clear whether she had been shot.

The gunman fired shots outside the lab and then fired more inside, Barker said. He was found dead inside the building.

"There were people running all over the place when the officers first responded," Barker said. "It was pretty chaotic at first."

He said he didn't expect any further details would be available Tuesday.

‘She wasn't crying’
Witnesses said a woman in a bloodied lab coat ran into a nearby Subway sandwich shop after the shooting.

Alina Kurtavenao, who works at the Subway, said the woman had blood on a leg and on her forehead.

"She wasn't crying, she wasn't scared," Kurtavenao said, adding the woman appeared to be in shock.

Other businesses in the area included a framing store, a bank and a locksmith. The office mall was evacuated when police arrived.

Legacy MetroLab conducts drug and alcohol testing for employers and others, company spokeswoman Kathleen Gorman said.

"There were probably six people working there," said Travis Bonser, a teller at a Chase Bank across the street. "It's just a regular lab."

The middle-class community of Tualatin has about 26,000 residents and is the site of the practice facility for the Portland Trail Blazers.
