A teenager has been jailed for killing three of his friends after inhaling laughing gas behind the wheel and speeding at more than 100mph.
Thomas Johnson, 19, was driving a BMW when it crashed into a lamppost and a tree, killing three passengers, on the A415 in Oxfordshire, last year.
He was jailed for nine years and four months at Oxford Crown Court on Wednesday for causing the deaths of Elliot Pullen, 17, Ethan Goddard, 18 and Daniel Hancock, 18, by dangerous driving.
