Cause of crash which killed King's Lynn motorcyclist, 17, 'unknown', inquest told
The cause of a crash in which a teenage motorcyclist died remains unknown, an inquest has heard today.
Tyler Bunn, who was 17, suffered fatal injuries when the Honda bike he was riding was in collision with road signs on Main Road, Clenchwarton, during the early hours of August 29 last year.
A hearing at the Norfolk Coroner's Court in Norwich this afternoon was told that Tyler had left a friend's house in Terrington St Clement shortly before the crash.
He had ridden there with another friend earlier in the evening and had swapped bikes with him for the return journey, the court heard.
Tyler, who lived in Gaywood, was riding a short distance behind his friend when the machine left the road and went across a grass verge, colliding with a village sign and speed limit signage. Despite efforts to revive him, he was pronounced dead at the scene.
A post-mortem examination gave the medical cause of his death as multiple traumatic injuries due to a road traffic collision.
Toxicology reports showed alcohol and compounds found within cannabis were present in his system at the time of the crash. The court heard he had drunk vodka at the address in Terrington St Clement.
A police forensic collision investigation report said there were no defects on either the bike or the road that might have contributed to the crash.
It suggested the most likely cause was a combination of the effects of alcohol and cannabis consumption, together with a lack of familiarity with the machine.
The court heard that Tyler and his friend had ridden in excess of the speed limit for part of the journey and Tyler had also received letters from the police about speeding and riding on footpaths.
But it was also stressed that the quantity of both substances did not exceed legal limits for driving.
And, summing up, area coroner Yvonne Blake said: "We don't know the reason for the crash."
She recorded a conclusion of death by road traffic collision and offered her condolences to members of his family who attended the hearing.
