A convicted serial killer on death row in California has been linked to the cold case killing of a pregnant woman in 1977 after a photograph of the victim was found among a collection in his possession.
, known as the "Dating Game Killer" because of an appearance on a US game show in 1978, has already been convicted of five murders and confessed to two more and could have killed up to 130, police believe. Thornton's sister recognised her picture and contacted investigators to submit her DNA. Wyoming police were able to recognise the location in the photograph as that where Thornton's body was found decades earlier. On Tuesday (20 September) he was charged with Thornton's murder.
