A terrifying infographic has been released which shows the other side of serial killers – and perhaps the most dangerous.

YourLawyer.com has released a graphic which shows the most prolific serial killers, but from a medical perspective. In other words, all of the doctors, nurses and medical professionals who have preyed on patients.

There are a total of 35 individuals in the list and the statistics are truly terrifying.

Harold Shipman has the most deaths to his name, with records suggesting that he killed at least 250 people in a 23-year killing period. He did this by administering lethal doses of diamorphine to elderly patients before falsifying records. While the infographic just focusses on serial killers from a medical perspective, no serial killer across any other walk of life has killed as many people as Shipman. In other words, he is the most prolific serial killer of modern-day times.

Shipman was convicted in 2000, but that hasn’t stopped a number of other medical serial killers over the last few years.

For example, in the early 2000s, Niels Högel was convicted of killing more than 85 people in Germany (although some belief that the true figure was closer to 300). It was found that he was administering lethal doses of heart medication, so he could try and resuscitate them in front of his colleagues.

Or, there was the chilling story of Kermit Gosnell who was active up until 2011. This physician murdered newborns by cutting their spinal cords with scissors, after being born alive during third-trimester abortion attempts.

Gosnell’s conviction is somewhat different to many of the other criminals featured on the infographic. While Gosnell used some form of surgical equipment, most used poison or overdoses. They then used their medical knowhow to mask their crimes and, in most cases, proceed undetected for years.

While there have been some cases, such as Gosnell, that have appeared in recent times, the infographic shows that Shipman was the UK’s last medical serial killer. This is most probably due to the increased scrutiny that doctor’s now have on their work and death rates, in the aftermath of Shipman’s conviction.
