A passenger who suffered "horrific injuries" in a coach crash which claimed two lives has become its third victim six months after the accident.
John Carruthers leaves a widow, Norma, and two daughters
John Carruthers, 78, of Chertsey, Surrey, was hurt when the National Express coach overturned on the slip road of the M4/M25 on January 3.
He died on 1 July but police could not say if the crash caused his death.
But post-mortem examination results released on Friday confirmed he died as a result of his injuries.
Mr Curruthers, who was known as Jack, was discharged from hospital but returned many times for further treatment.
'Sense of humour'
He leaves a widow, Norma, two daughters and five grandchildren.
He was born in Glasgow and after school became a research petroleum chemist for BP in Hamburg, Germany. He was a keen golfer and enjoyed Scottish dancing, running the local society for many years.
He and his wife had lived in the Chertsey area since 1957.
The family said: "Jack's sense of fairness, consideration for others and sense of humour never left him even after the accident and his horrific injuries, and in intensive care he would joke with the nurses.
"He remained positive and worked hard to regain his fitness, intending to drive and play golf again."
The coach was travelling from Heathrow Airport to Scotland following the Christmas break.
The driver was arrested and is due to answer police bail on 23 July.
Police said the investigation was "ongoing".
