In August, 26-year-old Dwight Smith Jr. was hit and killed by a car on South Pettigrew Street in Raleigh.
The new evidence is hair and a piece of fabric found stuck underneath a car that police say was there the night of the hit and run.
"It's a hole in my heart," said Dwight Smith Sr. "This is something that will never go away, never go away."
The new evidence, however, is giving him some relief.
A search warrant shows they found the hair and fabric stuck under a car. There's no word yet if that hair and fabric match that Dwight Smith Jr.
A white cross with purple roses now sits in the same spot Smith was found on a Saturday in early August. Police say he was at a party at 14 South Pettigrew Street.
"My son wouldn't have been over there period, if it wasn't for the guy's birthday," said Smith.
People at the party then left to go downtown. One of the cars police say they left in was a 2002 Honda Accord. It's the same car they found that hair and fabric.
Witnesses told police Smith got into a fight with people at the party, and then sat in the street where he was hit. The warrant shows whoever smith was fighting was also in that Honda.
"I know he didn't lay in no street and let a car hit him," said Smith. "I know better than that."
Smith's father believes someone at that party knows something.
"I've known them since they were kids," he said. "[They] haven't even come and gave me their condolences. I know there was something else involved with this."
For now, even with police not saying if they have a suspect; Smith is feeling hopeful for the first time since his son's death.
"I just want whoever did this to pay for it," he said.
There is a $1,100 reward offered by the family for information that leads to an arrest.
