6. Genene Jones
Genene Jones worked as a pediatric nurse. On the surface, she seemed to know what she was doing. Beneath her professional facade, however, this nurse was involved in something terribly sinister. She used her training to harm many helpless children.
While only a handful of deaths have been definitively tied to Jones, it is estimated that over 50 children and infants died in her care. Her method was nothing short of horrific. She would inject these small children with any number of drugs, usually heparin or digoxin, just enough to overwhelm their fragile bodies. They would often die of heart failure as a result.
