A man and a woman have been convicted of murdering a vulnerable woman they should have been caring for almost two decades ago.
Margaret Fleming vanished "from the face of the earth" around December 1999. Her body has never been found.
Edward Cairney, 77, and Avril Jones, 59, were found guilty of murdering the missing woman following a seven-week trial at the High Court in Glasgow.
Jurors found that they murdered her between December 18 1999 and January 5 2000 at their then home in Inverkip, Inverclyde, or elsewhere in Scotland, and tried to cover up the crime for almost 18 years.
It is not known how they killed her.
Jones was further convicted of fraudulently claiming £182,000 in benefits by pretending that Ms Fleming - who was reported missing in October 2016 - was alive.
The jury took around three hours over two days to reach their majority verdict on the murder charge.
The pair "literally got away with murder for 16 years", the prosecution said.
Police launched an investigation after it became apparent in October 2016 that Ms Fleming was missing.
Routine social services inquiries were said to have sparked concerns over her whereabouts.
The case attracted major police resources and significant media attention as it was claimed the last independent sighting of her was actually at a family event on December 17 1999.
As the inquiry progressed, it appeared something "sinister" had happened and she may have come to harm.
Specialist search teams combed the cottage where she lived and excavated its grounds for clues to help track her down.
Her supposed carers were arrested in October 2017.
During their trial, which began in April this year, Ms Fleming was described by prosecutors as a "friendless and lonely" young woman who had significant difficulties.
She went to live at the Seacroft home of the accused following the death of her father when she was a teenager after those closest to her "didn't want her".
By October 1999, various benefits for Ms Fleming flowed into the household, which was said to have had financial difficulties.
The Crown suggested it was "tempting" for the couple to have the money but not the "inconvenience" of looking after her.
How, and exactly when, Ms Fleming died, may never be fully known. It remains, as the defence highlighted, a case without a body and without a crime scene.
Holding them jointly responsibility for the death, the Crown claimed the couple "literally got away with murder for 16 years".
Money was the motive behind the "terrible" crime, the court heard, with the pair cooking up an "elaborate scheme" to conceal her disappearance.
They were ultimately brought down by "greed, arrogance and lies" after Jones made claims of Ms Fleming having "fantastical" illnesses and conditions in correspondence with benefits officials.
As police zoned in on the couple, their fabricated stories to explain Ms Fleming's absence became increasingly "farcical" as they tried to reconcile claims she was both working as a gangmaster and capable of travelling overseas, and that she was someone with major difficulties requiring a number of benefits.
Judge Lord Matthews will sentence the pair on July 17.
