Adam Alexander's body has never been found
A 37-year-old businessman has appeared in court charged with murdering a lorry driver who went missing a decade ago.
Bike enthusiast Adam Alexander, who was 38 at the time of his disappearance from Errol in Perthshire, has not been seen since 14 November 1999.
Thomas Pryde appeared at Perth Sheriff Court accused of killing Mr Alexander by repeatedly striking him with a metal object or by some other wilful act.
He is also accused of disposing of Mr Alexander's body at an unknown place.
Mr Pryde, whose address was given as c/o HMP Saughton, made no plea or declaration and the case was continued for further examination by Sheriff Lindsay Foulis.
Mr Pryde, who until recently ran a plumbing and engineering company, made no application for bail and he was remanded in custody.
The investigation into Mr Alexander's disappearance was sparked after he failed to keep an appointment at his home with someone interested in buying his motorbike.
The case was initially treated as a straightforward missing persons inquiry until the end of 2007 when its focus was changed.
Tayside Police then confirmed it was being treated as a murder inquiry, but despite extensive efforts, no trace of Mr Alexander's remains have been discovered.
Earlier this year Mr Alexander's mother, Tricia Bremner, lodged a petition at Perth Sheriff Court to have her son formally declared dead.
