A drink-driving Doncaster dad had taken cocaine before driving a stolen motorbike that fatally hit a speed bump, an inquest heard.
Robert Wilson, aged 30, was riding the blue Kawasaki with 48-year-old friend John Deere – who witnesses said was ‘holding a can of beer’ – as pillion passenger when tragedy struck.
Refuse collector Mr Wilson, of The Avenue, Bentley, had taken cocaine, a ‘significant’ amount of amphetamines and had consumed around 1.5 times the legal limit of alcohol before driving.
The pair, neither of whom were wearing crash helmets, had travelled from Arksey Lane onto The Avenue, Bentley, shortly before the accident occurred at around 8.40pm on April 29.
Witness Jennifer Goodwin said she saw the motorbike crash as she was walking along Elm Crescent towards The Avenue, which is fitted with a number of speed bumps.
She said: “As I watched the motorbike leave the speed bump it seemed to fly into the air.
“I’ve known Rob for 14 years, and as I watched Rob was flung into the air and he landed in the middle of the road. At this point he wasn’t moving.
“The other man landed on the right-hand side.”
Witness Lesley Oaks said she saw the motorcycle approaching as she was driving down The Avenue, which has a 20mph limit, and said it was travelling at a ‘great speed’.
Collision investigator PC Sean Morris said from CCTV footage he calculated Mr Wilson and Mr Deere were travelling at an average speed of 33.4mph from the point that they entered The Avenue to the point of the collision 402 metres away.
But he said the vehicle would have been travelling faster and slower at certain points and scratch marks on the road showed the bike was going at more than 52.3mph as it approached the crash scene.
PC Morris concluded: “The cause of the collision was the road calming measure which caused Mr Wilson to lose control of the vehicle.”
The blue Kawasaki motorcycle had been stolen just hours before the collision but PC Frank Martin said police had no evidence connecting Mr Wilson or Mr Deere to the theft.
Mr Wilson was taken to Doncaster Royal Infirmary for treatment after emergency services were called.
He was transferred to the Hallamshire where he died ‘surrounded by his family’ on May 4, 2015.
Mr Deere was also taken to DRI with serious injuries. He has since recovered.
Consultant pathologist Kim Suvarna, who conducted Mr Wilson’s post-mortem, concluded he died from the blind force, thoracic and head trauma sustained in the one-vehicle collision.
Dr Suvarna recorded Mr Wilson’s use of cocaine, alcohol and amphetamines as the secondary cause of death, which he said ‘impaired his ability to operate a motor vehicle’.
Assistant coroner Mark Beresford recorded a conclusion of road traffic collision.
Mr Wilson’s family paid tribute to the dad-of-one. They said: “Robert was a devoted father to his daughter, who was his little princess, and a loving son. He will be missed by everyone.”
