LEXINGTON, N.C. (WGHP) -- A new billboard in Lexington paired with a cash reward is putting a spotlight on one of North Carolina’s oldest missing persons cases. It’s been 44 years since 13-year-old Donna Barnhill disappeared from her Lexington neighborhood. On Friday, it was announced by the Wilmington-based nonprofit CUE Center for Missing Persons. The billboard sits right across from the Davidson County Sheriff’s Office on Highway 64. It’s a bright red with Barnhill’s photos along with bold letters asking anyone with information to come forward. They're offering a $5,000 reward for that information.   “Regardless of how she is brought home, as long as she is, that's all that matters to us,” said Summer Goodwin, Donna Barnhill’s cousin. Barnhill was just 13 when she was last seen walking near her home on Hemstead Street in Lexington in March 1981. She vanished without a trace. Barnhill’s family had endured tragedy before her disappearance. Her older sister died in 1966. The death was ruled a homicide. Now, her family hopes to reunite the two sisters at last. “To be able to bring her home ... would mean the world to me and my family,” Goodwin said. Friends, family and volunteers from the CUE Center for Missing Persons gathered to announce the billboard, and they also walked the neighborhood where Barnhill was last seen.  They left flyers and knocked on doors. With them was her childhood friend Lee Hedrick. She remembers their days playing on the same street. “She was funny. She was really, really funny," said Lee Hedrick, Barnhill’s childhood friend. The nonprofit behind the billboard has never stopped fighting for answers. “CUE has chased down leads from North Carolina all the way down to Florida in order to try to bring her home ... After exhausting every type of search sector, all types of technology, everything ... still do not have her home,” said Mary Messer, a CUE Center for Missing Persons volunteer and searcher. Police hope the new effort will help turn up the temperature on the cold case. “It definitely has a potential to increase the number of tips and potential leads that come in to us ... We're looking forward to that. We hope it does,“ said Captain Luke Davis with the Lexington Police Department. The $5,000 reward will only be in effect for 90 days, and the offer will expire on July 10 at midnight.   Anyone with information should call the Lexington police at (336) 243-3302 or the CUE Center for Missing Persons 24-hour line at (910) 232-1687. ...read more read less
