One week after a hit-and-run left a runner dead in Roanoke County, police say they have found a "vehicle of interest" in the case.

But Lt. Matt Viar said Monday afternoon that police have not named a suspect in the death of Thomas Farrell, and they want the public to continue to call in tips.

The white 1998 Jeep Wrangler that was located Monday afternoon "is only considered of interest in the investigation" of Farrell's death, police said. They would not say where it was found or what led police to be interested in the Jeep.

Sgt. Tim Wyatt estimated that the investigation has produced more than 100 tips and maybe 200.

"This vehicle may have absolutely nothing to do with this incident," he said.

Wyatt said police had received multiple tips about the Jeep, but he declined to elaborate. He said investigators already had ruled out a Ford Explorer that had come under suspicion after an anonymous tip.

Farrell, a 49-year-old lawyer, was struck Jan. 28 while running along Springlawn Avenue near Cave Spring Elementary School. Crews were called about 5:45 a.m. after a resident found his body in the street.

The avid runner had been wearing an orange reflective vest, according to a police affidavit filed in court.

Wyatt said the tips that mentioned the Jeep Wrangler did not come from either of two police checkpoints that were designed to generate fresh leads in the case.

Police held the second checkpoint Monday morning from 5 until 6. Officers stopped cars at Springlawn Avenue and Ranchcrest Drive and handed out fliers asking drivers to call if they had information on the hit-and-run.

Police hoped to encounter people who travel the area early in the morning as part of a routine and who might have seen something the morning Farrell was killed. Officers set up the first checkpoint the morning after the accident.

Some drivers told officers Monday that they already had one of the fliers. Others said they didn't know anything about what happened.

A man in a pickup truck told police he would be happy to help if he could. "Hope you get him," the man said as he pulled away from the checkpoint.

Officers operating the checkpoints also were on the lookout for suspicious behavior and other signs such as dents or other damage to vehicles, Wyatt said.

The police affidavit says that Farrell's injuries suggested "he had been struck by a vehicle with a larger higher body style consistent with a truck or sports utility vehicle."

Wyatt declined to say whether police discovered fragments of a vehicle or other evidence that pointed to a particular type of vehicle.

Anyone with information on the case is asked to call police at 562-3266.
