A man who tried to rape a stranger and murdered her in a bid to avoid detection has had an extra five years added to the time he must spend behind bars before becoming eligible to apply for parole.
Judges at the Court of Appeal in London increased the minimum term being served by Glenn Nelson, 30, of Arborfield, Berkshire, to 30 years after hearing submissions on behalf of Solicitor General Oliver Heald that the original 25 years imposed last October was "unduly lenient".
Nelson was jailed for life after pleading guilty at Reading Crown Court to the murder and attempted rape of mother-of-three Krishnamaya Mabo, the wife of a Gurkha.
He waived his right to attend today's proceedings during which Lady Justice Hallett, sitting with two other judges, stressed that whatever the length of the minimum term, the sentence imposed on Nelson was one of life imprisonment - and the Parole Board would have to be satisfied that it was safe for him to be released.
But she added that given his background - including previous convictions for attempted rape - "that seems at present an unlikely prospect".
Mrs Mabo was murdered as she we nt for a walk in woodland near her garrison home in Arborfield last June.
Nelson, who lived in a mobile home in Eversley Road, Arborfield, had gone out looking for women to attack on the day he killed 39-year-old Mrs Mabo, but had been scared off by other people or dogs.
The alarm was raised by Thaluman Mabo when his wife of 20 years did not return home and she was reported missing.
Her body was found near a tree in an area known as Long Copse and a post-mortem examination found she died from asphyxiation.
Speaking after the hearing, the Solicitor General said: "This was an appalling and shocking case where a man set off from home with a settled intention to commit rape. It was the misfortune of Krishnamaya Mabo, a wholly innocent victim, to encounter him.
"She was murdered so as to prevent her from identifying and giving evidence again Nelson.
"Mrs Mabo's husband served in the Royal Gurkha Rifles for our country. Our thoughts are with him and all the Mabo family because of their tragic loss.
"It is reassuring that the Court of Appeal has increased the original sentence, which was too lenient."
