Watch: Logan Mwangi's 14-yeat-old stepbrother questioned by police after killing the five-year-old

This is the moment a 14-year-old boy told police to tell his mum to "f*** off" as he was questioned over the murder of his five-year-old stepbrother.

On Thursday, Craig Mulligan was jailed for life with a minimum of 15 years for killing Logan Mwangi, whose body was discovered in the River Ogmore on 31 July last year.

Mulligan carried out the fatal assault with his stepfather, John Cole, in the flat where they lived in Lower Llansantffraid, Sarn.

Angharad Williamson, Mulligan's stepmother and Logan's biological mother was also convicted after the judge found she stood by and “did nothing” to prevent the killing.

Police found Logan partially submerged, wearing dinosaur pyjama bottoms and a Spider-Man top just 250 metres from his home north of Bridgend, South Wales.

The youngster had suffered 56 external cuts and bruises, and “catastrophic” internal injuries, which were likened to a high-speed road accident.

In the police tapes, broadcast in an ITV documentary, Mulligan claimed he was helping Cole, 40, fly-tip rubbish when he was instead helping to dispose of Logan's body.

Mulligan told detectives: "I woke up in the middle of the night and then dad [Cole] came into the living room with me.

"I know we weren't meant to do it but we grabbed some of the rubbish from the garden and we chucked it in the river.

"Now, it was all in like black bags and everything, I don't know what was in the bags I can't remember. And then about 20 minutes after, we went back out to check whether it had gone down.

"We didn't say anything, we were trying to be as quiet as we could because we didn't want to wake Logan or Angharad up."

In a second clip, Mulligan tells the police he thinks Williamson is "saying whatever she wants to get out of the f***ing cells."

In the interview, he says: "Can you tell my mum [Williamson] to f*** off?"

When asked why he said: "Because she's blaming me and my dad [Cole] for everything when we haven't done anything. Neither has my dad."

"Now, I'm just sick of this. She's just saying whatever she wants to get out of the f***ing cells."

The shocking details of the case have sparked calls for a nationwide independent inquiry into children’s services in Wales to prevent similar tragedies from happening again.

A social services investigation is already underway as Mulligan had only returned to the care of Cole just five days before the murder in July last year.

After a judge allowed the identity of Mulligan to be made public yesterday, it was revealed that a foster family whom the teenager stayed with claimed to have heard him say he wanted to kill Logan.

A support worker also heard Mulligan singing: “I love kids, I f****** love kids, I love to punch kids in the head, it’s orgasmic.”

Logan's stepfather John Cole, 40, was told he would spend at least 29 years behind bars, and 14-year-old Craig Mulligan was detained for a minimum of 15 years. Issue date: Thursday June 30, 2022.

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

Logan’s stammer is said to have worsened, becoming particularly bad around Cole. He wet himself more frequently and began self-harming.

Friends of the couple said Cole told them he did not like Logan, and others said his attitude changed after becoming obsessed with the idea that Williamson had cheated with Logan’s father, Ben Mwangi.

After Williamson gave birth to Cole's child he was reluctant to let Logan see the baby and later claimed the boy had tried to smother the infant.

Medics made a safeguarding referral to the police after Logan suffered a broken arm in August 2020.

By March, due to concerns over Cole’s behaviour, 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.

The Welsh Government said it would “closely consider” the results of a children’s services inspection and a review of events before Logan’s death.

“This is a tragic case and our thoughts remain with everyone affected by Logan’s death, particularly his family,” a spokesman said.

“We await the findings of the recent inspection of Bridgend County Borough Council Children’s services, conducted by Care Inspectorate Wales.

A judge told Cole at Cardiff Crown Court that he would spend at least 29 years behind bars while Williamson, 31, would serve a minimum of 28 years custody.

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