The PSNI has begun the process of exhuming the body of Daniel Rooney at Milltown Cemetery.
The 18-year-old was fatally shot in the St James Crescent area of west Belfast on 26 September, 1972.
A post-mortem wasn't carried out on the teenagers body at the time of his death, however hospital records show there was an entry but no exit wound from a bullet.
Senior Investigating Officer, Detective Chief Inspector Neil McGuinness, said they hope to uncover any bullets that may remain in the grave:
A forensic team, which includes a forensic anthropologist and a pathologist, arrived at the Falls Road cemetery this morning.
