The mother and stepfather of five-year-old Logan Mwangi, whose battered body was found dumped in a river, have been jailed for nearly 30 years each.

The child's mother, Angharad Williamson, 31, has been jailed at Cardiff Crown Court for life with a minimum term of 28 years while stepfather John Cole, 40, has been jailed for a minimum term of 29 years.

A 14-year-old boy, who was today named for the first time was also sentenced at Cardiff Crown Court today after being convicted of Logan’s murder. He has been detained for life told to serve a minimum of 15 years.

Both Williamson and the youth were convicted of a further charge of perverting the course of justice – an offence Cole had admitted before trial.

Mrs Justice Jefford had to impose life sentences and has had to fix the minimum term of custody each defendant has to serve before they can apply for parole.

Passing sentence, Mrs Justice Jefford said: “You are responsible for Logan’s death and all the anguish that has followed from it.

“Because he was killed in his own home, it is not possible to be sure what has happened to him.

“Shortly before his death, at which time he was three feet five inches and weighed only three stone one pound, he was subjected to a brutal attack.”

The judge described the injuries Logan had suffered and added: “Also the sort of injuries seen in abused children.

“Inflicting these injuries on a small, defenceless five-year-old is nothing short of horrific.

Describing how Logan was shut in his bedroom for 10 days after contracting coronavirus, Mrs Justice Jefford said it was “extreme” and a culmination of treatment that had gradually “dehumanised him in the eyes of his parents”.

Both Cole and Williamson told police that Logan had been badly behaved in the day before he was discovered, “sitting on the floor and refusing to get up”.

“In all probability Logan was already dying because much of what you describe is consistent with the presentation of the injuries he had already received,” the judge said.

Rejecting Williamson’s version of events that Cole and the youth attacked Logan on the Thursday and she had run out of the house in an attempt to get help, Mrs Justice Jefford added: “That was made up after the event to protect yourself and shift the blame.

“You had an opportunity to protect your son from further injury and you did nothing.

“Whatever time the ferocious assault on Logan happened, he was for the most part of Friday injured or dying.

“Had any of you sought medical assistance he would have had an 80 per cent chance of survival despite the severity of his injuries.

“There was nothing that provoked the attack upon him. None of you saw Logan as a child to be cared for.

“I am also sure in this small flat that this fatal assault could not have taken place without your full knowledge or collusion.”

Talking about the cover-up, the Mrs Justice Jefford said what they did was “careful and calculated and not the product of panic”.

“It is impossible to imagine the terror a five-year-old would feel suffering those horrific injuries inflicted upon him by those regarded as his family with the compliance of his mother,” she said.

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

The judge said she did not believe Williamson had participated in the physical assault of Logan but was sure that Cole and the youth had.

Turning to Cole, the judge said: “You carried out a ferocious attack on a small, defenceless child.”

To Williamson, the judge said it was clear that her relationship with Logan had changed when Cole came into their lives in April 2019. “Logan became superfluous, and in your eyes, he became a badly behaved and naughty child that no one described.”

Logan, a previously “smiling, cheerful little boy”, was discovered in the River Ogmore in Pandy Park, Bridgend,on the morning of July 31, 2021.

Police found him partially submerged, wearing dinosaur pyjama bottoms and a Spider-Man top, just 250 metres from his home.

During the trial, Cardiff Crown Court heard the youngster had suffered 56 external cuts and bruises, and “catastrophic” internal injuries, which were likened to a high-speed road accident.

Experts said the injuries could have only been caused by a “brutal and sustained assault” inflicted on Logan in the hours, or days, prior his death. They also said the injuries were “consistent with child abuse”.

In the months and weeks leading up to his death, Logan had been “dehumanised” by his family, prosecutors said.
