Documents Reveal Details Of Alleged Road Rage Shooting Involving NJ Officer

GAMBRILLS, Md. (CBSNewYork/AP) -- Court documents reveal a witness' account of an alleged road rage incident that Maryland police say led to the fatal shooting of a motorist by an off-duty detective from New Jersey.

A witness told investigators that the confrontation started when Joseph Walker's minivan cut off Joseph Harvey's car on Saturday night, according to court documents.

Harvey's passenger, Adam Pidel, told police that Walker pointed a gun at them as the vehicles swerved at each other. The two then pulled over on the shoulder of the ramp from northbound Route 3 to Interstate 97 near Millersville, police said.

"The two vehicles came to rest there on the ramp," said Maryland State Police spokeswoman Elena Russo. "The drivers exited the vehicles and another altercation ensued."

Police said when the drivers got out, Walker announced he was a police officer. Pidel said he heard several shots as he ran for cover.

"Certainly, this appears this is some sort of aggressive behavior gone bad," Russo said.

Walker, 40, is from Eastampton, N.J. and works with the Hudson County Prosecutor's Office. He is charged with second-degree murder and manslaughter.

A spokesperson with the Hudson County Prosecutor's Office issued a statement that said: "We are aware of the fatal shooting incident involving one of our detectives, who was off-duty and traveling in Maryland with his wife and children."

Walker is being held on $1 million bond after a bail review hearing on Monday.
