Did Yorkshire Ripper, Peter Sutcliffe, kill petrol pump attendant Gordon Snowden?

At around 2am on Easter Monday 1979, 60 year-old Gordon Snowden was brutally attacked.

He was found beside his kiosk with severe injuries to the head.

Mr Snowden was working his shift as a petrol pump attendant at Sutton Bridge Motors in Lincolnshire.

A cash till had been stolen during the attack and has never been traced.

A Citroen 2CV car was seen on the garage forecourt shortly before the murder - but this line on inquiry was not fruitful.

Gordon Snowden later died in hospital.

Nobody has been charged with his murder.

Ex-police intelligence officer Chris Clark believes that Yorkshire Ripper, Peter Sutcliffe, attacked Gordon Snowden, as well as three other men.

Mr Clark thinks Sutcliffe killed bookmaker Fred Craven in 1966, attacked taxi driver John Tomey in 1967, and killed cemetery gardener George Ellis in 1967.
