Mother Rachel Fee and her partner Nyomi have been found guilty of murdering her two-year-old son Liam Fee in Fife.
The couple were found guilty of assaulting and killing the young child at his home near Glenrothes in March 2014.
They were also convicted of a catalogue of abuse against two other children.
The guilty verdicts were delivered after a seven-week trial at the High Court in Livingston. The couple had blamed another boy for the murder.
However, the jury found that Rachel and Nyomi Fee had subjected the toddler to an escalating pattern of cruelty during his short life.

- Will lessons be learned from Liam's death?
The couple remained impassive as the jury found them guilty of all the charges against them.
Liam Fee's father, Joseph Johnson, was in tears at the verdict and consoled by friends.
In the days before his death, Liam suffered a broken leg and arm. He was killed by a blow to his abdomen which was so severe that it ruptured his heart.
The jury found Nyomi and Rachel to be jointly responsible for his murder.
In addition, they subjected two other boys to a series of physical and psychological abuse over two years - including forcing one to sleep in a makeshift cage and another to sleep in a room with rats and snakes which they said "ate little boys".
Social services had been alerted to the Fees but had failed to take any action. Fife Child Protection Committee said it would carry out a significant case review.
