A nurse convicted of killing four elderly patients with insulin overdoses was sentenced to life in prison on Tuesday, AP reported. The trial judge said that Colin Norris, 32, must serve at least 30 years in prison before being eligible for parole. «You are, I have absolutely no doubt, a thoroughly evil and dangerous man,» said Justice John Griffith Williams, presiding at Newcastle Crown Court. Norris was also convicted of attempting to kill a fifth patient. Prosecutors said he gave overdoses of insulin to his victims. Police began investigating following the death of Ethel Hall, 86, at Leeds General Infirmary in November, 2002. She was found to have 12 times the normal level of insulin in her blood. Police expanded their investigation after checking records at the infirmary and at St. James's Hospital, where Norris also had worked. He was also convicted of killing Doris Ludlam, 80, Bridget Bourke, 88, and Irene Crookes, 79, and of attempting to kill Vera Wilby, 90. Norris was arrested on Dec. 11, 2002, but not charged until Oct. 12, 2005.
