Logan Mwangi murder: Killer mum wants conviciton reviewed

Speaking about the cover-up, Jefford said his actions were “careful and calculated, not the product of panic.”

“It is impossible to imagine the horror a five-year-old child would experience in the face of the terrible injuries inflicted on him by those who were considered his family, with his mother’s consent.”

The hiding of Logan’s body in the river has been described as “heartless”, “calculated and planned”.

Jefford told the trio that “they were all responsible for Logan’s death and all the pain that resulted from it.”

“It’s impossible to know for sure what happened to him because he was killed in his own home,” he said.

He described the injuries Logan suffered as “the kind of injuries seen in abused children.”

Logan, previously a “smiling, cheerful little boy”, died after being subjected to a “brutal and sustained” attack at his home, leaving him with 56 “catastrophic” injuries, including extensive bruising to the back of his head and lacerations to his liver and intestines.

It was said that Cole would be sentenced to at least 29 years in prison, while Mulligan would serve at least 15 years. All three were convicted of Logan’s murder in July 2021.

Mulligan – his name could only be made public after a judge vacated the sentence anonymity order, external – He is not Cole’s biological son, but he raised him from the age of nine months and sees himself as a father figure.

On Wednesday, Williamson was briefly seen on screen with black hair and glasses as he listened to the hearing at HMP Downview Prison in Surrey with a mental health support worker.

He did not speak at the hearing and Coroner David Regan said he understood he “wanted to observe”.
