She was a murderer who lived in Alabama. She usually went by "Marie". Marie killed her husband in 1975 and tried to kill her daughter in 1978 -- both times by injecting arsenic. After conviction, bodies were exhumed of other relatives which also showed high levels of arsenic contamination.



What motivated Audrey Marie Hilley to kill has remained unclear, even now, decades later. Probably it was money, but she didn't reap a lot from her evil deeds.



Marie Frazier married Frank Hilley in 1951. They had a son (Michael) in 1952, and a daughter (Carol) in 1960. Both Frank and Marie worked, achieving a moderately high middle class income. But Marie was profligate -- her spending habits often stretched the family finances to the limit. What's more, she had numerous affairs, and was eventually caught by Frank in bed with her boss in 1974.



About this time Frank was already suffering from ill health. In May 1975 he saw a doctor about his problems, and very shortly was dead, official cause was hepatitis.



Marie went on a spending spree with the money (not that much, about $31,000). Her mental health declined over the years. She had never much liked her daughter Carol; it appears that Marie started to poison her in 1979, afraid that Carol was trying to go off and live her own independent life. By late 1979, Mike and other relatives were convinced that Marie had a part in Carol's mystery illness -- it was determined to be arsenic poisoning.



In 1980 Marie absconded while still on bail for her crimes. In the meantime, using the false name Robbi, she met and married a man named John Homan in 1981, in Florida. In 1982 she told John she had to do some travel to see relatives, including her twin sister who lived in Texas. In the next bizarre twist, "Teri" turns up on John's doorstep, saying that "Robbi" had died. "Teri" then resumes "Robbi's" old job and living with Homan.



Work colleagues were sure that "Robbi" and "Teri" were the same woman, eventually alerting the police.



Under questioning, Teri/Robbi finally admitted she was actually Audrey Marie Hilley.



Marie was sent to prison for her violent crimes. One day in February 1987 she didn't come back to the open prison where she was incarcerated. After four days she was found wandering around outside, and soon died of hypothermia.
