New Jersey authorities say they won't file charges against a police officer who struck and killed a 10-year-old boy with his squad car.

The Gloucester County Prosecutor's Office said Friday that Franklin Township Patrolman Nicholas Locilento's action "was not criminal in nature."

He was one of three officers speeding to a nonemergency call on a wet roadway at around 7 p.m. on Dec. 28. Authorities say three boys were heading to a sleepover.

Police say an older boy ran across the road and yelled that a car was coming. Ten-year-old Matthew McCloskey ran into the road and was hit by the police car.

The prosecutor's office says police are allowed to speed to calls. The officer was traveling 74 mph in a 50 mph zone when the crash occurred.
