Dougherty is accused of locking Kilrain, his brain-damaged wife, in a bedroom for five years after she suffered an aneurysm. Kilrain, 46, weighed 81 pounds when police found her body Feb. 25 surrounded by decaying food and human waste. In addition to murder, Dougherty, 53, an employee of an auto shop in Townsend, Del., is charged with manslaughter and abuse-neglect of a vulnerable adult. Dougherty's attorney said his client is innocent, and that Kilrain died of "natural causes." An autopsy concluded that she died of starvation and dehydration.
