WASHINGTON (AP) — A U.S. law enforcement official says the suspected gunman at the Fort Hood Army base in Texas is now believed to be dead from a self-inflicted would.

Fort Hood confirmed the shooting on the base in a brief statement Wednesday evening. The statement also said emergency crews were on the scene and that further details were not yet known.

The official says reports circulating within the Justice Department indicate the shooter has died of what appears to be a self-inflicted wound. The official spoke on the condition of anonymity because the investigation is still ongoing.

The identity of the shooter and the number of victims were not immediately known, although a senior U.S. defense official said earlier one person is dead and 14 are wounded.

The official spoke on condition of anonymity because the official was not authorized to discuss the information publicly.

The Texas Army base was the scene of a mass shooting in 2009. Thirteen people were killed and more than 30 wounded in what was the deadliest attack on a domestic military installation in history.
