STABBED 70 TIMES; KILLING IN POSH SUBURB This deranged hubby wrongly believed his sons had been fathered by another man so he launched a savage and sustained knife attack on his wife as their boys slept upstairs KILLING FRENZIED ATTACK AT HOME Husband pleads guilty to reduced charge of culpable homicide.
Robert Kerr, 39, attacked Xin Xin Liu, also 39, as their two sons slept upstairs at their home.
A judge heard how the mum of two suffered more than 70 wounds during the horrific killing last April.
A group of Xin Xin's relatives were in court yesterday.
Some wept as the grim details of her death were revealed. Kerr faced a murder TURN TO PAGE 5 FROM FRONT PAGE charge as he appeared at the High Court in Glasgow. But prosecutors accepted his guilty plea to the reduced charge of culpable homicide on the grounds of Kerr's diminished responsibility.
They said he was suffering from "an abnormality of the mind" at the time of the attack in Newton Mearns, near Glasgow.
As he was being held by police after the killing, Kerr told officers: "I found out tonight they were not mine."
Prosecutor Jane Farquharson said he had "suspicions" that a friend was the father of his children.
But, Farquharson told the court: "A paternity test recently carried out ... has since confirmed that Robert Kerr is the biological father."
Xin Xin had moved to Scotland from China about 15 years ago to study law at Aberdeen University. It was there she met Kerr, who was doing a computer course. They got married in 2003.
Kerr was latterly a lecturer at West College Scotland in Paisley while Xin Xin was training to be a translator.
They were described as a "quiet and private couple" and relatives were not aware of any problems between them. But, in early April - just a couple of weeks before the killing - Kerr contacted his GP complaining of stress in respect of "work and personal issues". He added he was suffering from anxiety, insomnia and spoke about "paranoid feelings".
However, just four days prior to the attack, Kerr spoke to a nurse and said he had been feeling much better and appeared to be sounding "chirpier".
It changed on April 26 when Kerr, wearing a dressing gown, fatally attacked Xin Xin. He went on to make himself a hot drink while she lay dead.
Just before midnight, Kerr rang 999 and admitted to emergency services: "I have just killed my wife. I murdered her in a stabbing frenzy."
biological father the PROSECUTOR " He went on to say there was "blood all over the place".
Police discovered Xin Xin lying on the kitchen floor with a knife still in her body.
A number of blood-stained items were found at the couple's house, including a milk carton. The advocate depute said: "Kerr has since admitted that he made himself a hot drink after this incident."
A post mortem later revealed Xin Xin had suffered a total of approximately 76 wounds.
The court heard that Kerr has since been receiving treatment at the State Hospital at Carstairs, Lanarkshire.
One doctor said his "ability to control his conduct" that night was "substantially impaired by reason of abnormality of mind".
He was said to be suffering from a "delusional disorder" including his belief about the paternity of his children.
the Judge Lord Boyd yesterday imposed an interim compulsion order for Kerr to remain at Carstairs.
First offender Kerr will return to the dock in November.
Just over an hour before her killer husband dialled 999, Xin Xin had been joking with Chinese friends online.
The court heard she pulled out of plans to meet up with them for dinner days later.
Farquharson said Xin Xin told how she could "no longer attend" and was "joking that the rest of the group would have to eat more".
