ROXBURY, NJ – Aided by a drone and a hovering helicopter shining a spotlight, police on Wednesday night searched the Kenvil section of Roxbury for a man on the run who escaped after sprinting into a Kenvil sand quarry.

The search began at about 11 p.m., after a motorist refused to stop when Morris County Park Police Officer Anthony Brunone tried to pull him over on Route 46 for a motor vehicle violation, said Morris County Park Police Lt. Chris List. He would not reveal the nature of the violation, but indicated that the car did not belong to the man being sought.

Instead of complying, the motorist tried to evade Brunone by driving into a residential area south of Route 46, said the lieutenant. He eventually stopped the car on 1st Street in Kenvil and took off running down a path that leads to the County Concrete property about 1,000 fee to the south, according to List and police radio transmissions.

Brunone chased the man on foot but couldn't catch him, List said. "The guy just had him beat," said the lieutenant. "He had a bit of a head start, and with it being foggy ..."

That led to the deployment of a Morris County Office of Emergency Management drone equipped with thermal imaging equipment and a State Police helicopter with a powerful spotlight. The chopper left at about 1:30 a.m. Thursday, but police on the ground continued their work.

 List, today, said the investigation continues but he insisted the public was not in danger.

"The car has been returned to its registered owner," said the lieutenant. He said witnesses indicated the man on the run left the area. "There should be no concern in the immediate area regarding this," List said.

Chief Gabe DiPietro said police feared the man went into a body of water on the County Concrete property. “It started out with a guy who wasn’t stopping for a motor vehicle violation,” DiPietro said. “He took off and went into the County Concrete area. There’s a pond in there and we thought that maybe he went into the water. That’s why there was a massive search.”
