Sean Buckley and Chloe Thomas from Tonypandy have been sentenced to an additional 3 years and 10 months in jail after the Court of Appeal increased their prison sentences.
Sean Buckley, 29, was found guilty of the murder of his partner’s 17 month old son, Finley Thomas, at Cardiff Crown Court in June.
Chloe Thomas, 25, was found guilty of child cruelty, by failing to intervene in the harm that her son was suffering.
Baby Finley suffered a fractured skull and broken ribs at the hands of Buckley, who claimed that Finley had fallen down the stairs.
He also had historical injuries consistent with being physically assaulted, neglected and having been exposed to illegal and prescribed drugs.
Chloe Thomas was said to ‘purposely ignore his suffering’ and didn’t seek medical attention for her son until it was too late.
Buckley originally received a life sentence, with a minimum term of 17 years in prison.
He will now serve a minimum term of 20 years
Thomas originally received a 20 month sentence for child cruelty.
It's been raised to 2 years 6 months.
The Lord Chief Justice, Lord Thomas, ruled her original punishment "unduly lenient" at London's Criminal Appeal Court.
Both Buckley and Thomas's sentences were referred to the court by the Solicitor General, Robert Buckland QC.
