See story at http://www.news-herald.com/general-news/20150917/killer-who-left-prison-farm-in-72-is-dead A man who was convicted of throwing a student nurse to her death from a hospital roof in 1958 later walked away from a prison work farm and lived under an alias for decades, even marrying and earning a college degree, before he died in 2004, authorities said Thursday. A six-month investigation by a cold case unit of the U.S. Marshals Service found that Shirley Campbell died of a heart attack in New Mexico at age 67 after living for more than three decades as Edward Davis. Using that identity, Campbell married a woman who had no clue about his past, earned a bachelor’s degree in sociology and was hired by New Mexico as an employment counselor. Campbell was convicted of killing 19-year-old Sylvesta Andy, who was a student nurse and a patient at a hospital in Hamilton, Ohio, where Campbell worked as an orderly. Campbell was accused of sexually assaulting Andy in a hospital elevator, chasing her to the roof and then pushing her to her death five stories below.
