Elizabeth Barlow - First Case of Murder By Insulin 1957

In the early morning hours of the 4th May, 1957 doctors attended the home of Kenneth and Elizabeth Barlow.  Elizabeth had been discovered apparently drown in her bath.  On the surface a tragic loss of a young mother.  But how does a healthy woman simply pass away whilst in the bath with no sign of trying to even attempt to save herself?  Suspicions began to mount that foul play was involved.  Until an eagle-eyed pathologist found 4 injection sites on her bum.  Newly developed techniques detected insulin in the tissues and Elizabeth was not a diabetic.  Let’s dive into the first documented case of murder by insulin.
