SERIAL killer nurse Colin Norris was jailed for life today for the murder of four elderly patients who were in his care.

Norris, 32, from Egilsay Terrace, Glasgow, killed the women with massive doses of insulin while working at two hospitals in Leeds.

Jailing him at Newcastle Crown Court, Mr Justice Griffith Williams said: "You are, I have absolutely no doubt, a thoroughly evil and dangerous man."

Norris, who was described by detectives as “extremely arrogant” showed no emotion as he was he was told that he would serve at least 30 years in jail.

Police said Norris showed no remorse for killing Doris Ludlam, 80, Bridget Bourke, 88, Irene Crookes, 79 and Ethel Hall, 86, while he worked at the Leeds General Infirmary (LGI) and the city's St James's Hospital. He also tried to kill Vera Wilby, 90, but she survived.

The nearest the prosecution came to outlining a motive was to suggest that Norris disliked working with the elderly.

The judge said: "You are an arrogant and manipulative man with a real dislike of elderly patients.

"The most telling evidence was that observation of one of your female patients, Bridget Tarpey, who said 'He didn't like us old women'.'

The judge said Norris disliked the elderly because they needed too much care and he formed the belief that Norris was "essentially lazy'.

"Only you know why that dislike was so much that you decided to kill.

"Despite months of evidence, I am no wiser as to your motive.'
