A fresh investigation has begun into the death of a teenager whose body was found outside Gartocharn.
Police have launched a probe in a bid to shed light on how Dean Geary died.
The 19 year-old’s body was discovered on the A811 Drymen to Gartocharn road on Sunday, February 7, 2010.
It is thought he was trying to make his way home to Alexandria when he was killed.
Enquiries at the time revealed that before he died he had been on a night out with friends in Glasgow city centre.
He was captured by CCTV cameras around 2.40am in George Square and later, around 3.30am, he spoke to a friend and said he was in a taxi.
Around 5am Mr Geary was seen by three motorists walking on the A811 near Gartocharn towards Drymen.
The original investigation confirmed that Dean had died as a result of being struck by a vehicle.
However, his wallet and Sony Ericsson mobile phone have never been found.
Detective Chief Inspector Kenny Graham who is leading the investigation said: “Over three years have passed since Dean’s death but I still believe there are opportunities to find out exactly what happened to him on the night of Saturday, February 6, 2010.
“Dean’s body was found around seven miles from his home and it has never been established why he was in the Gartocharn area or how he got there.
“I believe there are still people who have information about Dean who have not yet come forward.”
