TENAHA, Texas — Two students were killed and one was injured by a pickup truck that struck them at their school bus stop on Tuesday morning.

JaLyric Boykin, 7, died shortly after the accident. Her brother Nathan Cooks, 4, died in the hospital early the following morning.

Their aunt Danielle Cooks, 14, suffered extensive injuries but was expected to recover. A statement from the Tenaha Independent School District said her prognosis had improved, and she was scheduled to have surgery for a broken hip Thursday morning.

“Please keep these children and their family in your thoughts and prayers,” the district said.

A police report said that the school bus picking up the children had activated its lights, and traffic was stopping. But the pickup truck was reportedly approaching too fast, and it swerved to avoid cars that had stopped. The pickup went into a ditch and rolled several times before striking the children.

Charges against the pickup driver were pending.
