It’s thirteen years since David Findlay was last seen. David, a keen walker, left his home in Cardonald around 3pm on Monday 5 May 2008.
He never returned home and his family hasn’t seen or heard from him since.
The last confirmed sighting of David was around 6pm on Monday 5 May 2008 on Sauchiehall Street at West Nile Street.
Officers also followed up a number of unconfirmed sightings in Cumbernauld, Coatbridge, Milngavie, Kirkintilloch, Shettleston and Kilsyth. However, all attempts to locate David proved unsuccessful.
David is described as 5ft 4 ins in height and of medium build with grey receding hair and gold rimmed glasses.
