What happened to Logan Mwangi?

Logan’s body was found partially submerged in the river just 250m from his home on 31 July 2021.

His body had 50 external wounds and several internal injuries which were consistent with injuries sustained by those who had fallen from a height or been involved in a high-speed car crash.

No medical assistance was sought for the child, although his injuries were likely to have been survivable if he had been treated within hours.

Police detective inspector Lianne Rees said in court that Logan’s injuries were so severe that he would have required morphine.

CCTV from houses near the scene showed two of Logan’s killers - his stepfather John Cole and a teenage boy - moving Logan’s body in a sports bag to the river where they dumped it.

Rees told the court during the defendan’’s trial that they had treated Logan “like fly-tipped rubbish.”

After Cole had dumped Logan’s body, his mother, Angharad Williamson called the police to report her son missing and feigned distress when she was told that he had been found and was unconscious.

She was seen on police bodycam footage, she is seen crying and saying that Logan needs warm clothes, and his mother, even though she knew that her son was dead.

Cole, Angharad, and the teenager were all found guilty of Mwangi’s murder at a trial at Cardiff Crown Court in April this year, and were sentenced today (30 June).
