Logan Mwangi suffered brutal abuse before murder convictions in Wales
Logan Mwangi was found in the River Ogmore with 56 injuries and catastrophic internal damage. Angharad Williamson has now enlisted Tony Thompson to review her conviction.
Angharad Williamson has enlisted former police officer Tony Thompson to review her conviction over the murder of five-year-old Logan Mwangi. The courts have already found the evidence against Williamson, John Cole and Craig Mulligan proved to the criminal standard.
Logan’s body was found in the River Ogmore near his home in Sarn, Bridgend, shortly after 6.00am on 31 July 2021. At Cardiff Crown Court on 30 June 2022, Mrs Justice Jefford said the child had suffered 56 external injuries, mostly bruises, together with catastrophic internal damage. She said Logan was 3 feet 5 inches tall and weighed just 3st 1lb, and described blunt force trauma to the head, evidence of another non-fatal head injury at least 36 hours earlier, substantial internal bleeding, a tear to the lower part of the right lobe of the liver, a 5cm tear to the root of the small bowel mesentery and a torn duodenum.
Williamson, Cole and Mulligan were all convicted of murder. Cole pleaded guilty to perverting the course of justice, while Williamson and Mulligan were convicted of that offence after trial. Williamson received a life sentence with a minimum term of 28 years. The sentencing court also heard from Logan’s father, Ben Mwangi, in a statement, and the judge said the family had suffered a devastating loss.
A Child Practice Review into Logan’s death was published on 24 November 2022, and the Cwm Taf Morgannwg Safeguarding Board found service failures and concluded agencies could and should have acted differently. Under the Social Services and Well-being (Wales) Act 2014, that review process is required when abuse or neglect is suspected and a child has died or been seriously injured. The Welsh Government then made an oral statement on 29 November 2022.
A pre-inquest hearing at Pontypridd Coroner’s Court has now set Logan’s inquest for November 2026.
