The continuing search has involved local and state police and fire officials using squad cars, all-terrain vehicles, helicopters, and heat-sensing cameras, as well as media towers to track the motorist's route.
They've also been studying highway and store video footage and had a New Jersey State Police forensic team confirm the hair was human. Blood tests had not yet come back.
On Friday, Evesham police will use dogs to check a five- to 10-mile stretch of Route 70 and nearby roads.
"It's like a needle in a haystack, a shot in the dark," Friel said late Thursday.
But the search will continue.
"We're all in on this," Friel said. "We have a victim, a starting point, and a two-hour window."
The driver, who police said appeared confused during the stop, told them he had visited the Apple store at the Cherry Hill Mall and left about 6 p.m.
He became confused and lost, and was driving erratically shortly after 8 p.m. Tuesday when police stopped him at East Main Street and Knox Boulevard.
The Evesham officer saw the heavy damage to the front passenger side of the blue 1997 Ford Taurus, along with the hair and blood, and asked the driver whether he had been in an accident.
The man told him he didn't remember where the accident occurred, and later rode with officers for hours, trying to find the accident site.
The Cherry Hill man has a current license and hasn't been charged with any offense, police said. Evesham police did not release his name; his car has been impounded during the investigation.
Investigators obtained a video showing the driver's undamaged car leaving the Cherry Hill Mall, and on Thursday, they were checking video from other public highway and convenience-store cameras for clues.
They also were trying to determine whether an operating "Apple device," which they wouldn't identify, could be used with local media towers to determine the motorist's route.
The distance between the mall and East Main Street is about 11 miles and should have taken about 25 to 30 minutes to drive.
"We're using every available resource," Friel said. "We have ATVs in wooded areas along the highway and state police helping with a helicopter."
