VERSAILLES, Ind. (AP) — State police say three teenagers killed when two pickup trucks collided in southeastern Indiana had left a school function where they were supposed to remain the entire school day.

Sgt. Noel Houze said at a news conference that the six South Ripley High School students riding in the two trucks had been excused from school to attend an Indiana FFA Association event at a rural church near Versailles.

Houze says the trucks collided shortly after 9:30 a.m. Thursday after both drivers ran a four-way stop and one truck hit the other broadside. Both trucks went off the road and traveled about 100 feet into a cornfield.

Three other students riding in the truck were being treated at University Hospital in Cincinnati, about 40 miles east of Versailles.
