@independent: A 19-year-old who caused the death of three teenagers by dangerous driving after inhaling nitrous oxide and travelling at speeds of more than 100mph, has been jailed. Thomas Johnson was behind the wheel of a BMW 3 series when the car crashed into roadside furniture and a tree, killing three passengers, on the A415 in Marcham last year. During the sentencing hearing, prosecutor Neil Moore showed the court several short video clips recovered from the phones of those who had been travelling in the car in which a balloon, typically used to inhale the gas, could be seen “in the mouth of the defendant”, he said. On Wednesday he was jailed at Oxford Crown Court for nine years and four months.
