VALLIANT, Okla. (AP) - The Oklahoma Highway Patrol says a 6-week-old baby has died after the vehicle he was riding in collided with a cow on a rural road.

The highway patrol says the baby died Monday morning at a Dallas hospital. The collision happened Sunday night on a county road in McCurtain County about 3 miles north of Valliant.

The baby's mother and her three other children were treated and released from a hospital. The highway patrol says the vehicle crashed after colliding with a cow that had wandered onto the road.

The highway patrol says all of the passengers were properly restrained, either in car seats or by seat belts.
