Using an assault-type rifle, a man fired 15 to 20 shots at a federal building in Wheeling, W.Va. on Wednesday, the U.S. Marshals Service tells the AP.
Authorities said the suspect was killed by police during the assault.
The wire service reports:
"Chief deputy Mike Claxton of the Marshals Service in northern West Virginia says one officer was hurt by shattered glass inside the courthouse during Wednesday's shooting but no other injuries were reported.
"Claxton says the gunman was in a parking lot across from the courthouse downtown. He says officials are attempting to determine a motive."
The Wheeling News-Register reports witnesses say the man also shot at the nearby Wheeling YWCA.
The paper quotes Carla Webb Daniels, who witnessed the incident from across the street, saying she witnessed a man pull out a weapon and start shooting.
"I was so nervous, I couldn't believe it," Daniels told the paper. "People were scared and were banging on the doors asking to be let in."
