THE mother of a convicted paedophile who was beaten to death by one of his victims told a court how he “booted the hell out of him”.

Jeanetta Oldfield, the mother of John Mathers, said Kevin Caddick was completely calm prior to the attack, but then flew into a rage after saying: “You know what you did”.

Married father-of-five Caddick admits killing Mathers, his uncle, but denies his murder on the grounds of diminished responsibility, or loss of control.

He has waived his anonymity for the trial at Teesside Crown Court.

Mrs Oldfield said her son, who was jailed for three years in 2012 for sex offences, had come to visit her at her home in Fulbeck Road, Middlesbrough, on November 12 last year.

She described someone coming to her door and asking for ‘John’ and let him in, believing it was one of his friends.

She told the court: “He said [to her son]: ‘You know what you did’. And then he started booting hell out of him.”

She added: “When he started attacking him I went out of the front to see if I could get help.

“When my son wasn’t moving and he had a lot of damage done to him, then he left. And he never even noticed me.”

The trial heard a series of agreed statements including one from a neighbour of Jeanette Oldfield, Freda Charlton, who went to help her friend following the assault on Mathers.

She described seeing him on his back unconscious with a “lot of blood around his face and head”.

In another statement, PC David Stewart - the first officer to attend the scene - described how he tried to give first aid to Mathers, who at that stage was still breathing, before handing over to a paramedic crew who had arrived.

Mathers, 51, who was previously known as Harry Oldfield before a name change, was punched and kicked and suffered severe head injuries with a bleed on the brain before he died six weeks later in hospital.

Caddick visited another uncle, Edward Smith, who heard knocking and banging on his door in the early hours of November 12.

The 35-year-old defendant, of Carisbrooke Avenue, Middlesbrough, is said to have revealed “I’ve been up there and hit him”, and Mr Smith’s wife, Gillian, said he sobbed as he told them: “I think I’ve killed him.”

Caddick’s wife Elizabeth was called by the prosecution and she said her husband struggled to deal with the abuse he suffered as a young boy.

“He just couldn’t cope with what Harry did to him,” said Mrs Caddick.

The Crown’s case is that the motive for the attack was revenge and the jury has been told it was “vicious and unnecessary”. The trial continues.
