A BOY who killed little Logan Mwangi can today be revealed as a “pure evil” teen with a “desire for violence”.
The 14-year-old, who legally can’t be named, had a chilling history of “cruel” attacks on young children, vulnerable adults and animals.
He also made previous threats to kill five-year-old Logan, who was found dumped in a river near his home in Bridgend last July.
The boy was yesterday convicted of murder alongside Logan’s mum Angharad Williamson and stepdad John Cole.
It comes as…
It can now be revealed he was branded “pure evil” by a foster carer and “enjoyed causing anxiety and fear”.
The teen, who was trained in martial arts, was obsessed with horror film The Purge and violent video games.

Sadistic incidents included him stamping on a carer’s foot after she had an operation and attacking a pensioner.
He also hit a three-year-old child and would use his martial arts training to lash out at teachers with karate kicks.
One girl who was in the same foster family as the boy chillingly revealed how he tried to get her to play at the river alone.
He also asked her young nieces to play a “murder game” where he would put their bodies in black bags.
She said: “He seemed obsessed with killing people.
“He would talk about killing people all the time. He said if The Purge film was true he wanted to kill my mother and father and he made it seem as if he wanted to it be real life.”
The girl’s foster mum told how he had a “desire for violence” and would torture the family’s pet dog by spraying deodorant in its eyes.
He also grabbed the pooch, which had an injured pelvis, by its back legs.
The mum claimed she was “unnerved” by the boy, who would walk around smirking, and said he smashed a local park with a metal bat.
The teen told the carer he would kill her, her husband, daughter and the dog.
After he was arrested for Logan’s murder, the boy was heard singing “I love kids. I f***ing love kids. I love to punch kids in the head. It’s orgasmic”.
Prosecutor Caroline Rees QC said: “He repeated the phrase loudly. In the light of the mechanism of injury to Logan, the prosecution say that this is a significant comment.
“It certainly doesn’t demonstrate any sadness this five-year-old has died in traumatic circumstances.”
Logan was found with horrific injuries after being dumped in the Ogmore River near his home in Bridgend like “fly-tipped” rubbish.
In total the youngster had 56 external injuries to his head, face, torso arms and legs from a blunt force trauma.
He was covered in bruises including on his scalp and tongue and his brain was swollen.

Logan had received “catastrophic” injuries to his abdomen including a tear measuring 5.5cm by 3cm on his liver and a second rip on his bowel.
Tragically Logan is believed to have survived for several hours after the assault, meaning he may have been saved.
