Genene Anne Jones is a former pediatric nurse who killed somewhere between 1 and 46 infants and children in her care. She used injections of digoxin, heparin and later succinylcholine to induce medical crises in her patients, with the intention of reviving them afterward in order to receive praise and attention. These medications are known to cause heart paralysis and other complications when given as an overdose. Many children, however, did not survive the initial attack and could not be revived. The exact number of murders remain unknown, as hospital officials allegedly first misplaced then destroyed records of her activities to prevent further litigation after Jones' first conviction. While working at the Bexar County Hospital in the Pediatric Intensive care unit, it was determined that a statistically inordinate number of children Jones worked with were dying. Rather than pursue further investigation for fear of being suied, the hospital simply asked Jones to resign, which she did. She then took a position at a pediatric physician's clinic in Kerrville, Texas, near San Antonio. It was here that she was charged with poisoning six children. The doctor in the office discovered puncture marks in a bottle of succinylcholine in the drug storage, where only she and Jones had access. Contents of the apparently full bottle were later found to be diluted. Jones claimed to have been acting in the best interests of her patients, as she was trying to justify the need for a pediatric intensive-care unit in Kerrville. This act was not a successful means of achieving her goal.
