It's been more than 38 years since teenager Mark Haines was found dead on rural train tracks.
"It's 38-and-a-half and counting," his uncle Don Craigie told AAP.
Mr Craigie has spent each of those years fighting for answers after his 17-year-old nephew's body was found on the tracks outside Tamworth, in northern NSW, on the morning of January 16, 1988.
