A troubled teenager from Oklahoma was charged on Monday with threatening to "shoot 400 people for fun" in her former high school - and police said they found an AK-47 at her home.
Alexis Wilson, 18, made this paralyzing statement to a colleague at a pizzeria in McAlester, Oklahoma, showing her videos of her recently purchased assault rifle.
The authorities said that Wilson was expelled from McAlester High School after violent incidents and that he had already been suspended for being caught with a knife.
Deputies found the gun, along with six magazines and a 12-gauge shotgun with protective sheath, in Wilson's room at home.
Wilson explained that she was trying to convince her colleagues that gun owners are not all bad, a deputy minister wrote in an incident report.
The girl's mother said her daughter was saving for the rifle, which did not bother her because "Alexis always fired with guns and hunted".
The teenager has been accused of a terrorist hoax.
Wilson was detained at Pittsburg County Jail on a $ 250,000 bail. His next appearance is scheduled for September 27.
