20 baffling forensic cases that stumped everyone

The “Dr. X” killings
Sometimes even seemingly airtight forensic evidence is insufficient to convince a jury. That’s how Mario Jascalevich, a surgeon who always seemed to be “around” when other doctors’ patients died inexplicably following routine surgeries, apparently got away with the murder in 1975. Although an investigation revealed the doctor’s locker held 18 empty bottles of the poison curare – which was shown to be in the bodies of the victims – the jury chose to believe the doctor’s claims that he’d used the curare to conduct experiments on dogs. The patients’ deaths remain unsolved to this day.
