The family of James Hanratty, who was hanged for murder in 1962, are planning a fresh appeal against his conviction.

Hanratty was found guilty of shooting dead a civil servant and raping and shooting his lover in a lay-by near Bedford in August 1961.

Reporter Andrew Hosken investigates claims that DNA samples were contaminated, rendering the conviction unsafe.
