WALDWICK, N.J. — A police officer checking for speeders was killed when a tractor-trailer that didn’t try to stop rear-ended his parked car on a highway shoulder early Thursday, making him the second officer to die in the line of duty in the state this week, prosecutors said.

Officer Christopher Goodell was operating radar on Route 17 at about 1:30 a.m. when the truck went onto the shoulder and struck his unmarked car, pushing it into a retaining wall, Bergen County prosecutor John Molinelli said.

Goodell, who grew up in Waldwick and was a Marine Corps veteran, was pronounced dead at the scene. The 32-year-old was a five-year veteran of the police force.

Police Chief Mark Messner called him an outstanding person and an outstanding officer.

“He loved his country,” Messner said. “He loved his town. He loved his police department. He leaves behind his family and a young fiancee.”

The truck driver, Ryon Cumberbatch, was uninjured and called 911, Molinelli said. There was no roadway evidence Cumberbatch tried to stop, he said.

Cumberbatch, of New York, was charged with vehicular homicide and is scheduled to appear in court Monday.
