The mother of five-year-old Logan Mwangi has been found guilty of his murder.
Angharad Williamson, 30, her partner, John Cole, 40, and a boy, 14, have all been convicted of the same offence.
Logan’s father, Ben Mwangi, was in court to hear the jury return its verdicts.
The little boy had 56 external injuries when he was found in a South Wales river last July.
Williamson screamed “no, no, no” from the dock as the verdicts were announced.
Judge Mrs Justice Jefford interrupted the jury and the clerk to tell Williamson to be quiet before the verdict against the youth was given.
“Out of respect for your son and the youth please be quiet for the verdicts,” she said.
She told the jury they had performed an “exceptional public service” while listening, at times, to “very unpleasant and emotional evidence”.
The child, also known as Logan Williamson, was found dumped in the River Ogmore near his home village of Sarn in Bridgend on 31 July last year.
He was wearing mismatched pyjamas and was said to have undergone a “brutal and sustained assault”.
His injuries were described as similar to victims of high-speed crashes or someone who had fallen from a height.
When he died, he had been isolating for 10 days after testing positive for COVID-19 and was treated like a “prisoner”, the prosecution said.
In her closing speech, prosecution barrister Caroline Rees QC said Cardiff Crown Court had heard how Logan was a “smiling and cheerful” child.
But she added: “Behind the smile, he endured a harsh environment and was not treated with love.
“In the 10 days before he was discovered, he was being been kept like a prisoner in his small bedroom.
“What must he have thought about the way life was in those 10 days?”
Ms Rees said there was a “raft of powerful circumstantial evidence” that all three defendants took part in Logan’s murder.
They must have known what happened to Logan to cause his injuries, she added, concluding: “They were all involved…they’re putting their self interest first.”
