Medical professionals are supposed to help people but, shockingly, there have been several serial killer nurses who killed patients instead. Some of these nurse murderers haven't become as infamous as serial killer doctors like H. H. Holmes. However, this doesn't mean their crimes against humanity were any less heinous. In fact, the methods that some of these nurses who killed their patients used are disturbing enough to make you think twice about going in for that checkup.
Perhaps these individuals were able to get away with their crimes for so long because society views nurses as the ultimate caregivers. This makes it very difficult to consider that someone who has lost a lot of patients could actually be a killer nurse. The reality, though, is that every hospital worker has creepy stories about things they've seen, heard, and done. Medical nurses who were serial killers may not be one of the most common hospital oddities, but there have definitely been more of them than most people would ever guess.
Amelia Dyer is one of the most notorious serial killers in history. Although she was convicted of only 12 murders, evidence suggests her true body count was at least 400. The murders took place during a 20-year time span in the late 1800s, and all of her victims were babies.
Dyer was a trained nurse who turned to baby farming to make money. She would offer to adopt or nurse a child in return for a fee, but would typically kill the babies within days by drugging them with opium-based substances or smothering them. She actually served six months in prison for negligence in 1879 before returning to her murderous ways. Dyer wasn't arrested for her crimes until 1896. Her reign of terror finally ended permanently on June 10, 1896, when she was executed by hanging for the murder of 12 infants.
Interestingly, some have suggested that Amelia Dyer could have been Jack the Ripper; the murdered women would have been the victims of her botched abortions. However, there's little to no evidence to back up these claims.see more on Amelia Dyer
Arnfinn Nesset's case is unusual: he was caught, convicted, served time in jail, and eventually released. The former nurse completed his prison term and subsequent supervision period in 2005. Nesset is now living under a new, unreported name, which makes it impossible for the families of his victims to know his current location.
After he was caught in 1982, Nessen admitted to killing 27 patients at a nursing home with a lethal injection of the muscle relaxant drug suxamethonium chloride. However, he later recanted his confession, which extended his murder trial to five months. He was ultimately found guilty of killing 22 people, but it's believed his true body count is closer to 140.see more on Arnfinn Nesset
Edson Izidoro Guimarães was convicted of four murders in 2000. However, the medical nurse admitted to killing five patients, and some estimates place his probable list of victims at more than 130. All of these deaths happened between January and May of 1999. A coworker stopped the slayings by reporting it when he witnessed Guimarães injecting a patient with potassium chloride.
After he was arrested for his crimes, Guimarães stated that he had no regrets because he had helped people who were in irreversible comas. It's unknown if that was the true motive, but investigators suspected that he was killing people to earn $60 each by reporting their deaths to nearby funeral homes. Known locally by the nickname "the Nurse of Death," this serial killer was given a prison term of 76 years.see more on Edson Izidoro Guimarães
Daniela Poggiali Killed Her Patients, And Then Took Selfies With Them
Italian nurse Daniela Poggiali supposedly killed at least 90 of her patients on purpose because they annoyed her. While she vehemently denied the charges, the Italian government thought otherwise, and charged her in 2014 with the crimes. Not only was Poggiali present for 93 deaths during her time as a nurse - a very high number, according to authorities - she also took selfies with her dead patients. Police said she stole money and jewelry from her dead patients, and bragged to others that she killed them because they "annoyed" her.
