Logan Mwangi, five, suffered 56 external injuries and catastrophic internal damage at the hands of Angharad Williamson.

A mother who murdered her five-year-old son wants her case reviewed by the body which investigates potential miscarriages of justice. Angharad Williamson was jailed for life in June 2022 for the murder of her son Logan Mwangi, alongside his stepfather John Cole and a teenager, Craig Mulligan, then 14. On Wednesday, she appeared via video link at a hearing at Pontypridd Coroner's Court which set a date for Logan's inquest. Tony Thompson, a former superintendent with the British Transport Police, told the court: "I am conducting a review of her conviction." Logan's inquest has been set for November this year - more than six years after his murder. Mwangi's body was found in the River Ogmore, near his home in Sarn, Bridgend county in July 2021. Cardiff Crown Court previously heard that the attack on the "defenceless" schoolboy, who weighed 3st 1lb (20kg), was "nothing short of horrifying". It has been four years after those who were closest to Mwangi were convicted of his murder.
