DETECTIVES from Strathclyde are to question Gavin McGuire about two unsolved murders on the banks of the Clyde.

They are interested in two outstanding murder inquiries - one in Greenock in 1986 and the other in Irvine almost two years ago. In both cases, two young women met violent deaths. No trace was ever found of their killer or killers.

The first killing was just after midnight on June 2, 1986, when Elaine Doyle was making her way to her home in Ardgowan Street, Greenock.

The 16-year-old sales assistant never completed her journey and her partly-clothed body was discovered in a lane just behind her tenement home. She had been sexually assaulted and strangled.

A young man was seen acting suspiciously in the entrance to a block of flats near to the murder scene, but he was never traced. Police will now be trying to establish McGuire's movements that night.

The second case centres on the death of Irvine divorcee Shona Stevens in broad daylight in a public park as she made her way home from the shops.

Ms Stevens, 31, was dragged into bushes and savagely beaten.

She was discovered by a passer-by and flown to the neurosurgical unit of the Southern General Hospital in Glasgow where surgeons battled vainly to save her life.

She died three days later. Her mother made impassioned pleas for people to help the police and said that Ms Stevens little daughter Candice asked every day where her mummy had gone.

Despite sightings of three men and interviews conducted with more than 4000 people her attacker was never traced.
