Jonathan Carson was found shot to death inside his Colonial Avenue home in Elizabeth City on June 11, 2012.
Elizabeth City Police Chief Eddie Buffaloe says while investigators are still following several leads, no arrests have been made in the case.
In October 2012, friends and family raised $8,000 for a reward for information about the case, but that money is only now being added to the Crime Line reward of $2,000 to bring the total to $10,000.
Bob Carson, Jonathan's father, hopes the money will be motivation for someone to bring forward critical information to solve the murder.
"One little thing could trigger you to talk to that one person who knows something and they can open up a whole new world," Carson explained. "It won't bring him back. We know that, but we don't feel that people like that need to be walking the street."
