THE family of a teenager who was found dead after a night out has pleaded for information four years on.
The body of 19-year-old Dean Geary was discovered by a passer-by on the A811 near Gartocharn, West Dunbartonshire, in the early hours of Sunday, 7 February, 2010.
A police investigation concluded that he died of severe head injuries after being hit accidentally by a vehicle.
However, detectives say there are unanswered questions surrounding the case and are re-examining how the teenager came to be fatally injured.
Mr Geary’s father John, 46, from Alexandria, said: “It’s every parent’s worst nightmare, losing a child.
“If you have the slightest piece of information, please be brave and come forward. Don’t have it on your conscience. Someone must know something.”
Police have released CCTV footage of Dean Geary’s last movements in Glasgow city centre.
He and his friend Mark Craig were seen arriving at Queen Street railway station for a night out on the Saturday. He left the Tattoo nightclub alone at around 2am and was seen on CCTV in George Square at around 2:40am.
Other sightings put him near a taxi rank on the corner of Renfield Street and Sauchiehall Street at around 3:20am.
At 3:30am, he spoke to a friend and said he was in a taxi. An hour-and-a-half later, Mr Geary, an administrator at the Coulport naval base on the Clyde, was seen by three motorists walking on the A811 near Gartocharn towards Drymen.
Detective Chief Inspector Kenny Graham, who is leading the investigation, said: “We believe there are still some outstanding questions regarding Dean’s death and even four years on we are determined to try and find the answers.
“So I’m asking people to think back. Was Saturday 6 February, 2010, a significant date in your diary? Did you go out to celebrate a birthday or anniversary that night and did you see Dean in the city centre?
“We still don’t know exactly why Dean was on the A811 and what his movements were between being seen in the city centre and when his body was discovered.
“I firmly believe there’s someone out there with what might turn out to be crucial evidence which will help us find out what happened to Dean. I hope the footage will help jog someone’s memory and if it does, I would urge them to come forward.”
Police want to know how Mr Geary travelled from Glasgow to the Gartocharn area and what happened to his Sony Ericsson mobile phone and his wallet, which have never been found.
