The Murder of Logan Mwangi: Where to Watch Logan Mwangi’s Documentary

Logan Mwangi was a 5-year-old boy who was murdered in late July 2021 in Sarn, Bridgend, South Wales.

The precise nature of the events leading up to his death are difficult to ascertain.

However, it is believed that his mother, Angharad Williamson, his stepfather, John Cole, and Cole’s stepson, Craig Mulligan, participated in and were aware of physical attacks on Logan in late July which led to him developing severe external and internal injuries.

After his death, the household discarded Logan’s body in a river before denying any knowledge of how he died.

According to Wales Online, the subsequent police investigation found that he had been beaten to death.

Logan’s injuries were described as similar to victims of high-speed crashes or people who had fallen from a height – and a trial heard he had suffered 56 external cuts and bruises as well as “catastrophic” internal injuries.

The specifics of the case were reviewed, but the decision not to conduct a broader inquiry into children’s social services in Wales received some criticism.

The young age of Mulligan and the circumstances in which he joined the household also received some discussion.

Logan’s father, Benjamin Mwangi, has been campaigning to make it a law for estranged parents to be told if their child is under the supervision of social workers.

Williamson, Cole, and Mulligan were found guilty of murder in April 2022 and were sentenced to life in prison.

The concealment of Logan’s body in the river was described as “heartless”, “calculated, and orchestrated” by the judge.

Logan was described as the sweetest and most beautiful boy whose life has been tragically cut short.
