MERIDIAN, Idaho (AP) — A Nampa school bus driver has been charged with misdemeanor vehicular manslaughter after a crash that killed an 11-year-old boy in December.

The Canyon County Prosecutor's Office filed the charges Tuesday against 56-year-old Debra Boatwright. Idaho State Police say Boatwright was at fault for a Dec. 5 collision with a dump truck that killed sixth-grader Daniel Cook and inured four other children. Twelve children were on the bus.

Investigators concluded that Boatwright failed to yield the right of way when she pulled away from a stop sign west of Kuna.
