Two people were confirmed dead, including a gunman who opened fire Tuesday at a business complex in the U.S. state of Oregon, local media reported.

The gunman who opened fire at a drug-testing clinic in Tualatin, a city 13 miles (about 21 kilometers) south of Portland, killed one woman and injured several others before apparently fatally shooting himself, The Oregonian newspaper said in a report on its website.

The shooting occurred at about 11:48 a.m. local time and happened at Legacy MetroLab, which is a drug and alcohol testing site for local employers, according to the report.

The gunman's body was found inside the clinic, whose wounds were apparently self-inflicted and one woman was also found dead, Tualatin Police Chief Kent Barker was quoted as saying.
