BORDEN, Ind. (AP) — State police say a woman was killed when her minivan hit an oncoming school bus near Borden in southern Indiana.

Police don’t know why 36-year-old Sherri L. Anderson drove over the center line on Indiana 60.

There were no students on the West Clark Community school district bus. Police say the bus driver, 66-year-old Anna Marie Klein of Floyds Knobs, had minor injuries.

A coroner pronounced Anderson dead at the scene.

Police say the Pekin woman was driving west in her 2008 Dodge Caravan shorty before 4 p.m. today when she crossed the center line and hit the eastbound bus.

Anderson was alone in the van. Police don’t know if she or Klein were wearing seat belts.
