THIBODAUX, La. (AP)- Louisiana authorities say a 17-year-old faces terrorizing charges after schoolmates said he had a list of students he planned to kill, and two juveniles are accused of making less specific threats against other schools.

The sheriff of Lafourche Parish says the 17-year-old told investigators he’d planned to use a shotgun.

Officials in southwest Louisiana say a high-school and a middle-school student were arrested.
