New Jersey State Police say a car driven by a man taking his children to a baby sitter collided head-on with a tractor-trailer, killing him and his 5-year-old son. His 3-year-old daughter is critically hurt.

Thirty-seven-year-old Kevin Shelton, of Pittsgrove, was westbound on Route 40 when the crash occurred at around 7 a.m. Wednesday in the Salem County community. Authorities say it appears Shelton's car crossed the center line, but the cause of the accident remains under investigation.

Shelton and his son Cole died in the crash. His 3-year-old daughter, Cassidy, remained hospitalized in critical condition early Wednesday night.

A 47-year-old Tennessee man was driving the truck and hauling a load of paper. He wasn't hurt.
