Thirty years ago he murdered two innocent young women. Yesterday the 'World's End' murders suspect escaped justice

For 30 agonising years, the families of Christine Eadie and Helen Scott had hoped for justice. Last night, after a sensational day of twists and turns, that hope had turned to dust.

The man police are convinced killed the young women is back in prison, but not for their murders. Instead, Angus Sinclair, already a convicted double killer and paedophile, watched impassively as a judge halted his trial for their murders, citing insufficient evidence. He can never be retried for the crime. The decision led to angry recriminations, with police officers privately blaming prosecutors for bungling the case. The Scotsman understands that the jury was not told that samples of DNA, which could be linked to Sinclair, were found in ligatures used to kill the women.

Police believe he may be responsible for five other unsolved murders.
