A convicted rapist who murdered a mum-of-11 has finally been jailed after evading justice for 36 years.
Graham McGill, now 59, strangled Mary McLaughlin, 58, at her home after she had enjoyed a night out in Glasgow in 1984.
A DNA breakthrough described as one-in-a-billion helped to secure justice for the victim and her family.
Sexual predator McGill was sentenced to life in prison with a minimum of 14 years at Aberdeen High Court on Tuesday.

It was said previously that Ms McLaughlin had been out at bars playing dominoes before she was found dead in the Partick area.
She was last seen at a chip shop before heading home.
McGill followed her before using the cord on her dressing gown to strangle her, Glasgow High Court heard.
It was said that Ms McLaughlin was "friendly and trusting" - but "perhaps a little lonely".
Her body was found by her son days after her death.
Her death sparked a major police investigation and spawned dozens of lines of inquiry, but the cold case remained unsolved until modern DNA techniques placed McGill in her flat with a greater than billion-to-one likelihood, the trial heard.
Samples found on Ms McLaughlin's dress, inside the knot of a dressing gown cord, a cigarette end and on a black bra found near her third-floor flat were all attributable to McGill.
The killer's ex-wife, Suzanne Russell, also told jurors that in 1988 he had confessed to murdering a woman because he "just wanted to know what it felt like".
Prosecutor Alex Prentice QC also revealed during the trial that at the time of the murder McGill, who worked as a fabricator, was out on day release from HMP Edinburgh.
He said: "It was during parole liberation that he carried out the murder of Mary McLaughlin. He was 22 at the time."
McGill was sentenced to life imprisonment and will have to spend 14 years behind bars before any possible release on licence.
