'I Killed James': Chilling Moment 10-Year-Old Jon Venables Admits To Toddler's Murder

Chilling audio of a then-10-year-old Jon Venables admitting to the murder of a toddler has been heard publicly for the first time.

Venables, and friend Robert Thompson, murdered two-year-old James Bulger in 1993 in one of the most infamous murder cases in U.K. history.

During the police interview, Venables denies the murder and becomes increasingly distressed as detectives find holes in his story.

Venables admits to being in the shopping centre in Bootle, Liverpool, where Bulger was abducted from, but pleads his innocence to his mother.

"But we never got a kid mum. We never, we never got a kid," he told her.

But in a chilling twist, the detective reminds Venables of a conversation he had previously had with his mother.

"What was it you told us?" he asks.

"That I killed James," Venables quietly replies.

The audio was used during Venables 1993 trial, but was heard by the public for the first time on UK broadcaster Channel 5's documentary, James Bulger: The New Revelations.

In the program it was revealed that Thompson said he was "desperately sorry" for his part in the murder in a statement to the Parole Board in 2001.

The statement caused outrage in the U.K. when it was revealed Thompson said he had had a "better life" while in prison.

"I do feel aware I am now a better person and have had a better life and a better education than if I had not committed the murder," he said.

The pair became the youngest people to ever be convicted of murder in the U.K..

It was revealed during the trial they had lured the two-year-old from the shopping centre and walked four kilometres to traintracks, where they tortured and sexually assaulted him.

They stoned him, threw bricks at him and poured modelling paint into his eyes, before leaving his body on the tracks to be hit by a train.

Thompson was given a new identity when he was released from prison in 2001, as was Venables.

However, Venables' parole was revoked in 2010 after "extremely serious allegations" were made against him, and he was released again in 2013.

In 2017, Venables was returned to prison for the possession of child abuse imagery.
