This is the moment teenage killer Craig Mulligan turns on his stepmother in an expletive-laden and lie-filled police interview. Mulligan, just 13 at the time, had been arrested following the murder of his innocent and defenceless stepbrother Logan Mwangi.
The five-year-old schoolboy was murdered by his mother Angharad Williamson, stepfather John Cole, and stepbrother Mulligan before being dumped like rubbish in a river by the latter two killers. Logan suffered "catastrophic injuries" to his internal organs and his brain that were likened to those received in a car crash or fall from height. His little body was littered with dozens of injuries.
On Thursday his killers were locked up for a combined 72 years for the savage killing. Following an application by media organisations including WalesOnline teenager Mulligan was identified for the first time in connection with the murder.

Footage has now been released of Mulligan, who had only been living in Logan's home for a matter of days after the family courts awarded custody of the teenager to Cole with the support of Williamson, being interviewed by officers from South Wales Police following his arrest. He provided a tissue of lies to account for footage that showed himself and stepdad Cole, 40, walking to dump Logan's body in the middle of the night from Williamson’s home at Lower Llansantffraid, in Sarn, in the early hours of July 31, 2021.
He told police: "I woke up in the middle of the night. Then dad come (sic) into the living room with me. I know we weren't meant to do it but we grabbed some of the rubbish in the back garden and we chucked it in the river. It was all in black bags and everything. I don't know what was in the bags, I can't remember. Then about 20 minutes after we went back out to check whether they had gone down. We didn't say anything. We were trying to be as quiet as we can because we didn't want to wake Logan or Angharad. I don't know whether Logan was still there at that point because we didn't look."
In footage aired on an ITV documentary about the killing police officers describe how 31-year-old Williamson has "cracked" in interview and revealed how Craig was "in on it as well". Having challenged Mulligan about his involvement a female officer is then seen to ask the youth: "Is there anything you would like to add?" He replies: "Yeah. Can you tell my mum to f*** off for me?" The officer retorts: "Why's that?" To which Mulligan responds: "Because she's blaming me and my dad 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."

During the trial it was heard how Mulligan played his part in Logan’s death and the cover-up which saw the young boy’s body dumped in the River Ogmore. He also assisted in discarding Logan’s ripped dinosaur pyjama in a second trip to the area near the River Ogmore and after daybreak he and Cole walked the streets shouting Logan’s name – having dumped his body in the river just hours earlier.
It was later claimed by Williamson he had already admitted pushing Logan downstairs, causing him to break his arm, though during Thursday’s sentencing hearing judge Mrs Justice Jefford said she had not taken this into account as the evidence was “thoroughly unsatisfactory”. Mulligan was placed into Logan’s home just five days before the murder after Cole and Williamson were granted custody of him. He had spent the previous six months in care and was heard making threats to kill Logan – who he referred to as “the five-year-old”.
Two days before Logan’s body was recovered from the river Mulligan was said by Williamson to have attacked her son along with Cole. The court heard Cole punched Logan to the stomach two or three times and told Mulligan to “let him have it”.
Mulligan, who was trained in Muay Thai, was said to have swept Logan’s feet, knocking him to the floor while pressing his head against the floor. He was also said to have told his foster family he wanted to kill Logan.
Mulligan was found guilty of Logan’s murder at Cardiff Crown Court on April 21. He was sentenced alongside Cole and Williamson on Thursday when he was handed a life term with a minimum of 15 years.
The Murder of Logan Mwangi is available on catch-up on the ITV Hub.
