Nurses Who Kill - Season 2 - Eps 3: Efren Saldivar
Efren Saldivar confessed to killing 40 to 50 patients over an eight-year period. Quickly christened an "Angel of Death," he targeted patients who were already near death. Statistical analysis indicates that the total number of murders committed by Saldivar could be as high as 200, but the bodies were cremated after death long before he owned up to his deeds on the wards.
