The mum of a teenager who was stabbed 128 times said she is still fighting for justice after his killer spent just two hours in prison.

A documentary that aired on MTV UK on Wednesday night explored 18-year-old Alex Davies' horrific murder in woods at Parbold Hill near Ormskirk.

His twisted killer, Brian Healless, now 20, from Chorley, lured him to the remote beauty spot before stabbing him in a frenzied attack.

Healless spent just two hours in prison before he was transferred to a medium secure psychiatric hospital.

Alex had agreed to meet Healless, after chatting on the dating app Grindr.

Healless tried to set up similar outdoor meetings with four other males on Grindr in the days after the killing in April 2019.

Preston Crown Court heard that Healless was suffering from paranoid schizophrenia at the time of the killing.

A jury later rejected his partial defence that his responsibility for the killing was diminished by his mental state.

Alex's mother, Beverley Davies, told MTV correspondent Linda Adey she believes Healless has been feigning illness and that his actions were "too calculated".

Beverley said: "He should be in jail, and he should never, ever be let out."

The judge who sentenced him in March last year, to life with a minimum term of 24 years, said it was "extremely fortuitous" Healless was arrested before anyone else suffered the same fate as the "gentle, kind-hearted" sales assistant from Skelmersdale.

Healless was treated at Guild Lodge Hospital in Preston before conviction and was returned there on the day of his sentencing, following a request from the doctor overseeing his care - who also gave evidence for the defence at the trial.

A Ministry of Justice spokesman previously told PA news agency: "Prisoners may be transferred for treatment in mental health hospitals, based on assessments by expert clinicians, but will return to serve their sentence in prison once they are fit to do so."
