A man opened fire with a rifle Tuesday at a drug-testing laboratory in suburban Portland, killing one woman and wounding two other people before fatally shooting himself, police said.
No names were immediately released.
The Tigard-Tualatin School District was in lockdown following the shooting at Legacy MetroLab, which was reported at 11:48 a.m.
"There were people running all over the place when the officers first responded," Tualatin Police Chief Kent Barker. "It was pretty chaotic at first."
One of the wounded was taken to Emanual Hospital, while the other was flown to Oregon Health & Science University hospital in Portland, police said. Their conditions were not available.
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. I think she was in shock," she said.
Other businesses in the area include 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, according to company spokeswoman Kathleen Gorman.
"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."
With about 26,000 residents, Tualatin is a middle-class community about 13 miles south of Portland. It is also the site of the practice facility for the Portland Trail Blazers.
