Kelly A. Vaughn and her dog were in the parking lot of Mount Laurel Park in the Hewitt section at Upper Greenwood Lake when she was struck on Nov. 7, authorities said at the time.
On Thursday, Police Chief Timothy Storbeck cited video surveillance footage that he says shows a pickup truck and two smaller vehicles "present in the parking lot at or near the time of the incident" at different times.
"At this point in the investigation, the incident does not appear to have been intentional," the chief said. "However, the investigation has revealed that the driver should have known that their vehicle had struck an object in the Mt. Laurel parking lot.
"It also appears likely that the responsible party has direct knowledge of the area and may in fact be a local resident," he added.
Each of the vehicles entered the lot from Tyler Place and exited onto Warwick Turnpike between 7:14 p.m. and 7:40 p.m. that night, the chief said.
The first had been headed south on the turnpike, then turned right onto Tyler Place and left into the Mt. Laurel parking lot, he said.
It remained in the lot less than a minute and left, heading northbound on the turnpike, Storbeck said.
The second vehicle was traveling northbound and turned left onto Tyler Place, then left into the Mt. Laurel parking lot.
It remained in the lot for about five minutes before returning to the northbound turnpike, the chief said.
The third vehicle made a right onto Tyler place from the southbound turnpike and then a left into the lot.
It remained for about 90 seconds "and then exited the lot and traveled a short distance northbound before turning left onto Tyler Place a second time," the chief said.
"At this point in time, the Police Department is constrained from releasing further details of the recently obtained video surveillance footage," Storbeck said.
The footage, he said, "is currently under analysis by an outside agency with the intention of enhancing the quality."
Police "would like to be as forthcoming as possible with the community in regard to this tragedy while at the same time preserving the integrity of the investigation," the chief added.
He urged anyone who saw anything or has information that could help the investigation to call his department at (973) 728-2800 or (973) 728-2810 .
Callers may remain anonymous, Storbeck said.
