22:47 EDT, 4 August 2021 561 shares The step-father of five-year-old Logan Mwangi, the boy found dead in a Welsh river at the weekend, has tonight been charged with his murder. John Cole, 39, from Sarn, Bridgend, is due in court this morning, accused of carrying out the killing. Logan’s mother Angharad Williamson, 30, from Sarn, and a 13-year-old boy were also jointly charged with perverting the course of justice along with Cole. All three have been remanded in custody and will appear before Cardiff Magistrates' Court later. The 13-year-old cannot be identified due to his age. Williamson and Cole – who is also known as Jay Cole – had been a couple for around three years and got engaged in May, locals said this week.
