Authorities shot and killed an unidentified former police officer who allegedly fired more than 20 shots into the federal building in Wheeling, West Virginia, the Wheeling Intelligencer reported on Wednesday.

U.S. Attorney William Ihlenfeld did not give the suspect’s name but told reporters that the gunman was a former local police officer. The only injury reported during the attack was by a security guard at the building. One witness told the Intelligencer she saw the suspect using what she described as an assault rifle, which he later put down and reloaded before shooting at the local YMCA building.

Update, 7:04 p.m. EST: The Intelligencer reported that the suspect was identified as former Wheeling Police Officer Thomas Pickard, who worked with the department until he resigned in July 2000. No motive was identified for either the attack or his departure from the police.

WKKX-TV reported that Picard allegedly fired at the federal courthouse, and that two security guards in the building were treated and released from a local hospital after being hit by glass during the incident.

“We were all working and heard gunshots outside the building, Ihlenfeld told WKKX. “Windows were struck. We have a plan within the office where everyone goes into a safe room away from the windows. We took those steps.”
