BLAIR, Neb. (AP) — Authorities in eastern Nebraska say a 15-year-old boy has died in a single-vehicle crash.

The Washington County Sheriff’s Office says the boy was killed Saturday when a vehicle he was riding in crashed near Blair. They haven’t released information about anyone else in the vehicle but no other injuries were reported.
