The teenager who was convicted of murdering five-year-old Logan Mwangi can now be named.
Craig Mulligan has been described as a “monster” who made repeated threats to kill his five-year-old half-brother and gleefully chanted his love of hurting young children.
He was just 13 when he took part in deadly assaults on defenseless Logan Mwangi and helped 40-year-old John Cole dispose of the youngster’s body in the River Ogmore, Bridgend.
He had moved into the family home in Lower Llansantffraid, Sarn, just five days before – a fact prosecutors said was ‘no coincidence’.
Cole’s stepson, who had raised him from the age of nine months, Mulligan was said to have ‘idolized’ him and considered him a ‘God-like’ figure.
Cole had had a relationship with Mulligan’s mother, later becoming his carer.
The three moved to Wales for a ‘fresh start’ after repeated attempts by Mulligan’s mother to take her own life.
They later separated, but remained living in the same house with Mulligan, including while Cole began dating Angharad Williamson, who became pregnant soon after.
Mulligan was removed from his mother’s care after she violently assaulted him and he was cared for by Bridgend County Borough Council for six months.
Caroline Rees QC, prosecuting, said that by then Mulligan was already “a complex, troubled and violent boy”.
He was placed in foster homes, one of whom described how he made their lives a ‘living hell’ during the several weeks he was with them, and they became ‘terrified’ of him .
They said he made repeated threats to kill them, injured their daughter as well as the adoptive mother and their dog.
Concerns were raised after he asked two young girls if they wanted to play a ‘game of murder’ and should walk into black bin bags.
Although he spoke fondly of his stepfather, stepmother and youngest brother, the family said they noticed he would only refer to Logan as “the five-year-old child”. and talked about wanting to “kill the five-year-old”.
They said he had a ‘desire for violence’ and called him a ‘monster’ in court submissions.
The family said they informed Mulligan social worker Debbie Williams of their concerns, but Ms Williams denies this.
Cole and Williamson petitioned the family courts for custody of Mulligan and on July 26, 2021 they won and he came to live with them.
It is said that Mulligan loved the younger of his half-brothers but was jealous and disliked Logan.
Mulligan was tall for his age and had an interest in mixed martial arts, particularly Muay Thai, as well as video games – his username being “King hulk”.
During an alleged incident in the house, Mulligan allegedly “swept” Logan’s legs under him while using his hand to bang his head on the floor.
He had done it, according to Williamson, on orders from Cole, who had just punched Logan, knocking him backwards to the floor.
Just before 3 a.m. on Saturday July 31, Mulligan was captured by CCTV cameras following Cole out of the apartment and down to the river where they dumped Logan’s body.
He also joined in carrying out a bogus visible search for Logan as part of the family cover-up.
Mulligan was arrested around 6:30 p.m. on August 1, 2021 with Williamson inside Cole’s property.
During an interview, he maintained that he did not know what happened to Logan, but later admitted that he woke up to hear Williamson say “Logan is dead”.
After being briefed by detectives on Williamson’s allegations that he and Cole attacked Logan, Mulligan said, “You can tell my mom to fuck off for me. She blames me and my dad for everything.
After Logan was killed and Mulligan returned to the custody of local authorities, a carer overheard him repeatedly singing, “I love kids. I love children. I love hitting kids in the head. It’s orgasmic.
He told another: “I’ve done bad things but I’m not allowed to talk about them.”
During the trial, an anonymity order was imposed on Mulligan, preventing the reporting of any details that could identify him.
His lawyer said Mulligan had been diagnosed with multiple neurodevelopmental disorders.
Following his conviction and imprisonment for murder and misuse of justice, the press successfully called for the restriction to be lifted for reasons of public interest and transparency of justice.
