THIBODAUX, La. (AP) — A coroner’s investigator says a 15-year-old student who shot himself in the head after firing a shot over a teacher last week at a Louisiana middle school has died.

Mark Goldman, the chief investigator for the Lafourche Parish Coroner’s office, says eighth-grader Justin Doucet died Saturday morning at Terrebonne General Medical Center in Houma.

Police say Doucet entered Jessica Plaisance’s seventh-grade class and fired one shot over her head, missing her. He then walked into a nearby bathroom and shot himself with his father’s nickel-plated pistol.

Sheriff Craig Webre said Tuesday that Doucet’s writings indicated he had planned to kill four students and himself. No students were named as specific targets.
