Gemma's killer captured on video as he leaves her for dead

A DERANGED man was told by a GP to go on an anger management course just hours before killing an innocent teenage girl with a broken bottle.

Gemma Roberts, 18, suffered a severed jugular vein but managed to hold the wound and walk 40 metres to the Swan Hotel in Liversedge, West Yorkshire, after being slashed by mentally-ill Richard Hanson, 21, who has an IQ of just 78.

Hanson casually strolled to a garage shop, stole cans of lager and spent time with his girlfriend, drinking, chatting and kissing.

Yesterday, after he pleaded guilty to manslaughter on the grounds of diminished responsibility, Leeds Crown Court heard he had a history of mental illness going back to when he was three, when he kicked a teacher and set fire to a bed.

He had been in and out of youth custody, was on anti-depressants, and had gone with his mother to a GP the day he killed Miss Roberts.

The GP recommended him to see a community psychiatric nurse and go on an anger management course. The GP noted Hanson was aggressive, hearing voices and thought people were plotting against him.

Prison records showed that two months before the killing Hanson had been given a leaflet about controlling anger, despite saying that he was worried about hurting his cellmate.

A month before the killing, he told prison authorities that he felt "on edge" but it was recommended that he should release these feelings in the gym.

After his release from custody, two weeks before the murder, a probation officer described him as "genuinely not well" and urged him to see a GP, which he did.

After the killing, he told a psychiatrist that he was a "walking timebomb" and doctors decided he was suffering from an untreatable "psychopathic disorder" and was extremely dangerous.

On the evening of the attack on September 21, Hanson, of Stubley Farm Lane, Heckmondwike, had been drinking and had threatened several people, including his girlfriend.

Judge Peter Collier QC, sentencing Hanson to life in jail, set a minimum period in custody of two years and 320 days, but added that he may never be released and would be subject to a licence for the rest of his life.

The judge said: "Not only did you cut short her promising life but you have devastated her family, who will struggle to come to terms with her death for many days to come."

In a statement, Miss Roberts's family said: "We have been left with a massive hole in our lives."
