Student killer is jailed for life

Duncan pleaded guilty last week to the murder

A man who murdered a woman after performing "aggressively" at a karaoke bar has been jailed for life.

Judge David Paget said Christopher Duncan, 21, had an "unhealthy interest in violence" and should serve a minimum of 25 years.

Duncan, of Bethnal Green, east London, pleaded guilty last week to murdering student Jagdip Najran, 26, in May 2004 and stuffing her in a suitcase.

A psychiatrist told the trial Duncan was obsessed with violence and sex.

Sadistic tendencies

Sentencing Duncan at the Old Bailey, Judge Paget said: "You have an abnormal and unhealthy interest in violence and in particular, sexual violence towards women.

"It may be that you posed such a danger to women that it will never be safe to release you."

Jagdip Najran hoped to become a singer

Law student Ms Najran, who hoped to become a professional singer, had met Duncan at a karaoke night weeks before the murder.

On the night of the murder, the pair had met at a karaoke bar in London where Duncan was said to have been performing rapper Eminem's songs "aggressively".

They left the bar and stopped off for a drink at another pub before heading back to Duncan's flat, where various weapons and violent videos were found.

But at some stage he battered her over the head with an iron baseball bat and stuffed her in a suitcase, where she remained alive for another hour.

Judge Paget told Duncan: "You beat to death a beautiful young woman who was clearly attracted to you and accompanied you to your flat because she liked you and trusted you.

"There is no sensible explanation for what you did."

The court had heard that Duncan was a petty criminal who drank and took drugs, and was said by doctors to have a personality disorder.
