ROLLA, Mo. (AP) — A student at the Missouri University of Science and Technology is accused of threatening to open fire on the Rolla campus with an assault rifle.

Alexander Beetler, of St. James, was charged Wednesday on several counts, including making a terrorist threat. No attorney is listed for him in online court records.

The probable cause statement says Beetler’s father told authorities that his son had threatened to kill him and “empty the rest of the clips” on the Missouri S&T campus.

The father also said Beetler had an AK-47 rifle and about 900 rounds of ammunition, and the weapon was recovered during a search. The statement says Beetler was charged earlier this year in Kansas with discharging a firearm into an occupied dwelling.
