TEENAGE off-road motorcyclist, Ian Brand, caused the death of his father in a crash after drinking at a family barbecue.
Brand had been riding his brother’s unregistered Kawasaki 250 along with others at a track on the outskirts of Brechin when another group including his father arrived.
When the groups were getting ready to leave Brand’s father decided he would like to have a go on the rear of the motorcycle - neither man wore a crash helmet.
They rode off but on the return the bike appeared to swerve to the left of the path.
Brand’s father also seemed to lean to the left and both rider and passenger scraped against the chain links of the fence.
The motorcycle then collided with a concrete fence post and the pair were thrown from it with Mr Brand Snr landing about 10 metres away.
A subsequent post mortem showed a severe haemorrhage over the surface of the victim’s brain and a band of bruising to his neck.
Police arriving at the scene breath tested Brand and he was arrested after providing a positive sample. Almost two hours after the crash he was found to be double the drink-drive limit.
Brand, now 20, admitted causing the death of his father on August 22, 2009, by driving without due care and attention.
The judge, Lord Matthews, deferred sentence on Brand until next month for the preparation of a background report.
