(CBS/AP) WHEELING, W. Va. - A man with an assault-type rifle fired 15 to 20 shots at the federal courthouse in Wheeling, West Virginia, before security officers returned fire, critically injuring the man, the U.S. Marshals Service says.
CBS affiliate WDTV reports the gunman was transported to a local hospital where he died.
The station reports no one inside the building was hurt during the incident which took place at around 2:30 p.m. Wednesday. However, CBS affiliate WTRF reports Wheeling Hospital confirmed at least three people were admitted with injuries from the shooting.
