What is your precious daughter doing? Threatening to shoot a 12-year-old with an AR-15. All because of a text message.

Alachua County Sheriff’s deputies arrested a 17-year-old for threatening another girl with an assault rifle Tuesday night. The girl is facing a charge of aggravated assault with a deadly weapon with intent to kill, said Sheriff’s Office spokesman Lt. Steve Maynard.

A 12-year-old girl told officers the teenager threatened her with the weapon after the two started fighting, Maynard said. The girl said she was walking with her younger cousin when the teenager confronted her. The pair fought over an accusation the younger girl had sent text messages and made phone calls that angered the teenager. Maynard said the girl and witnesses reported the 17-year-old then went to her home and came back outside armed with the gun. The teenager told the younger girl she would shoot her, deputies reported. The weapon, which belongs to a person at the teen’s home, is an AR-15 assault rifle, Maynard said.
