Notice the “fact check” fails to mention she was only 28 years old. Not the type that usually suffers a fatal heart attack.
Generally you dont just black out from an undiagnosed heart condition. You feel weird and you sit down as your blood pressure drops.
Did they ever identify this undiagnosed heart condition that caused her to fall? If the head injury was the cause of death then how can they possibly conclude that the heart was involved at all. If it was still beating when she hit her head then it didnt cause the fall.
No mystery at all.
BS. This is a genuine Colombo style mystery.
