TUALATIN, Ore. -- Authorities say 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.
 
The woman who was killed was identified as 36-year-old Teresa Marie Beiser of Gladstone. Police say her husband, 39-year-old Robert James Beiser, died of a self-inflicted gunshot wound.
 
Court documents from Clackamas County Circuit Court show that Teresa filed for divorce from Robert on October 30th.
 
Teresa Beiser worked at the Legacy MetroLab in an office park across from a strip mall in Tualatin.
 
Tualatin Police Chief Kent Barker says the injured workers were a 20-year-old woman and a 63-year-old man.
 
He says the man was being treated at a Portland hospital for multiple gunshot wounds.
 
The 20-year-old woman was taken to another Portland hospital with non-life-threatening injuries. It wasn't clear whether she'd been shot.
