RUNNEMEDE -- A man shot "several times" from a passing vehicle on a South Jersey expressway early Saturday has died, New Jersey State Police said.

Authorities are now seeking the public's help in finding those involved.

According to the preliminary investigation, the unidentified victim was shot around 2:30 a.m. in the southbound lanes of Route 42 near Exit 14, said New Jersey State Police Sgt. First Class Gregory Williams.

It's believed another vehicle pulled up alongside the white Ford Fusion the victim was driving, opened fire and then fled the scene, State Police said.

The victim's vehicle then ran off the roadway.

He was taken to Cooper University Hospital in Camden where he later was pronounced dead, Williams said.

The victim was alone in his vehicle at the time of the incident.

More details about the man who died were not immediately released by police.

Anyone with any information about the shooting is asked to call New Jersey State Police at the Bellmawr Station at 856-933-0662. Anonymous tips are welcome, authorities say.

Some lanes on Route 42 were closed for a time while the investigation into the shooting was conducted. Lanes have since reopened.

The spot where the shooting took place is not far south of where Route 42 and Interstate 295 intersect.
