After Helen Kane’s body was discovered, police brought in a convicted killer for questioning.
Angus Sinclair, who grew up in the St George’s Cross area of Glasgow, was convicted of sexually assaulting and strangling his seven-year-old neighbour in 1961. Sinclair was sentenced to 10 years, though served just six.
By 1970, Sinclair was living on the nearby Hill Place, less than half a mile from where Helen’s body was discovered. He was soon quizzed by detectives over her death, but his family gave him an alibi - which was branded questionable.
