72 years for Logan Mwangi's killers

Logan's stepfather Cole was jailed for life and ordered to serve at least 29 years before he is eligible for parole. His mother Angharad silently wept as she was told she must serve at least 28 years. The youth defendant was sentenced to life detention with his minimum term set at 15 years.
Logan, a previously "smiling, cheerful little boy", was discovered in the River Ogmore in Pandy Park, Bridgend, South Wales, on the morning of July 31, 2021.
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.
Medics made a safeguarding referral to the police after Logan suffered a broken arm in August 2020.
By March, due to concerns over Cole, Logan and his younger sibling had been assigned their own social worker.
In June, a month before Logan died, the family were removed from the child protection register - meaning it was believed there was no longer a risk of significant harm.
A foster family the youth stayed with claimed to have heard him say he wanted to kill Logan.
Weeks before he died, Logan suffered a broken collarbone but medical treatment was never sought for him.
On July 20, Logan tested positive for Covid-19 and he was shut in his bedroom with a baby gate barring him from leaving.
Caroline Rees QC, prosecuting, said: "He had been kept like a prisoner in his small bedroom in the flat you saw, a room likened by Williamson as a dungeon."
