"I need some closure, I need some answers," Sumrell said. "I will never stop hurting till I find closure find some answers."
Sumrell says she has been searching for three years, eight months and two days.
Her son, 43-year-old Gerald May, was killed by a hit-and-run driver along NC 24, just east of Clinton. The busy stretch of road has a speed limit of 55 mph.
According to authorities, on July 6, 2006 May was walking along the road when he was hit by a truck. They say the driver did not stop.
An eyewitness told investigators she saw a big truck speeding down the road just a few miles before May was struck.
Sumrell says she has all the Highway Patrol and SBI paper work on the investigation.
Two years ago, Sumrell had a sign put up near the spot where her son was killed. She also hired a private investigator, but so far there are no leads.
She says she hopes a $5,000 governor's reward will be an incentive for someone to talk and end a nightmare no mother should suffer.
"You're never without it," Sumrell said. "Never out of your mind just going out to the store, see big trucks and wonder, did you do it? Getting out on the highway and you see truck after truck passing and all I can think about is are you the one, are you the one."
Its more than justice for her son, Sumrell says she also needs closure and peace.
If anyone has any information that can help investigators, they're asked to call the Sampson County Sheriff's office or the Highway Patrol.
