Male Nurse Murdered Patients with Insulin

Link Here

Colin Norris was found guilty for murdering four patients under his care. He was thought of as a serial killer,since he only murdered the weak and elderly. He dosed them with insulin. Insulin is an animal hormone that regulates the sugar take within the body. Norris overdosed the diabetic patients and caused them to go into a fatal coma. Police said that he seemed almost arrogant, since he was very aggressive. Even in court he showed no emotion but admitted he killed the four diabetic women. The patients he killed were well over 75 years of age. One of the victims was Ethel Hall, she slipped into a fatal coma- which Norris predicted, and at age 86 died. At the time of her death " tests later showed about 12 times the normal level of insulin in her blood."
Doris Ludlum, 80, Bridget Bourke, 88, and Irene Crooks, 79, were similar cases. Not only was Norris convicted for those four murders but also an attempted murder of Vera Wilby, 90.

Collin Norris scares me. Not only did he carefully pick the people he was going to kill but he made sure they died. Now I am sort of afraid of hospitals. There are so many horrid people in the world now hospitals aren't even safe.
