A paranoid lecturer who brutally stabbed his wife to death after wrongly believing he was not the father of their children has been detained at the state hospital.

Robert Kerr attacked Xin Xin Liu (39), at their home in Newton Mearns. He struck as his two sons slept upstairs and then went on to make himself a hot drink while Ms Liu lay dead.

A judge heard how the mother had suffered more than 70 wounds during the killing in April last year.

Prosecutors accepted his guilty plea in August to the reduced plea of culpable homicide on the grounds of his diminished responsibility after it was concluded he was suffering from “an abnormality of the mind” at the time of the fatal attack.

Lord Boyd ruled at the High Court in Edinburgh last week that Kerr be detained in the high security hospital in Lanarkshire in order that he can receive the appropriate medical treatment for a serious mental illness.

Lord Boyd said: “I am satisfied that treatment is available that would be likely to alleviate the symptoms or effects of the disorder and that if it is not provided there would be a significant risk.”
