Seven people have been killed while walking along Chattanooga roadways this year and all of those cases involved drivers who did not stop.

That number is three times more than last year and is one of the highest in the last decade.

Two of the seven cases remain unsolved. They happened on heavily traveled roads.

Jeffery Harris' body was found on the side of Highway 153 South between Jersey Pike and Shallowford Road in July.

The 51-year-old's sister sat down with Channel 3 after he was identified.

"He was left on the side of the road to die. That is not a death that I would wish upon anyone," Susan Dover told Channel 3 in August.

Investigator Tommy Seiter has spent the last four months trying to figure out who hit Harris but said without the public's help, he won't be able to answer Harris' family's questions.

"We don't have a lot of scene evidence. We don't have anyone there telling us what happened, our victim can't speak. A lot of roadway evidence, we don't have," he said.

Six and a half miles away on Ely Road sits another scene and more questions. It is where Roger Jones was hit and killed while walking to his mother's house one night in May.

His mother spoke with us after his body was found.

"The worst thing I could picture went through my mind about my son. The worst scenarios that I could think of about him; getting run over by a car," Angela Ponder said in May.

Traffic Investigator Chris Mullinix is in charge of Jones' case. He said the little bit of evidence in the case he does have isn't enough to find who is responsible.

"There were a few pieces of plastic. We were able to take the serial number from the piece of plastic and figure out a make and model and a year range of the car that was involved in the crash," he added.

Mullinix is looking for a dark colored Hyundai Sonata made between 2010 and 2014 that has or had extensive damage to the front.

Both men are working toward the same goal: solving these cases and giving these families the closure they deserve.
