A southern New Jersey student who was seriously injured in a deadly school bus crash last month has left the hospital.

Family members say 11-year-old Jonathan Zdybel was moved Wednesday afternoon to a rehabilitation center in Delaware.

Zdybel was hurt when the bus and a dump truck collided Feb. 16 in Chesterfield. The crash killed 11-year-old Isabelle Tezsla and also seriously injured her triplet sisters, who have since been released from the hospital.

The triplets' father, Anthony Tezsla, is a New Jersey state police sergeant.

Twenty-five elementary school students were on the bus when the collision occurred. Seventeen children were injured overall, though must only suffered bumps and bruises.

The cause of the crash remains under investigation.
