Donald HARVEY

A homosexual and self-styled occultist, Don Harvey attached himself to the medical profession at age eighteen, working as an orderly at Marymount Hospital, in London, Kentucky, from May 1970 through March 1971.
Harvey is notable for having kept his crimes from coming to light for over 17 years. The true extent of his crimes may never be known, since so many were undetected for so long. Harvey is also notable for having used numerous methods to kill, such as arsenic; cyanide; insulin; suffocation; miscellaneous poisons; morphine; turning off ventilators; administration of fluid tainted with hepatitis B and/or HIV (which resulted in a hepatitis infection, but no HIV infection, and illness rather than death); insertion of a coat hanger into a catheter, causing an abdominal puncture and subsequent peritonitis. Cyanide and arsenic were his favorite methods, with Harvey administering them via food, injection, or IV.
