The bestselling author who wrote a book claiming to see heaven after falling into a coma was in the middle of a $3million malpractice lawsuit.

Eben Alexander became famous after his book 'Proof of Heaven: A Neurosurgeon's Journey into the Afterlife' became a New York Times bestseller, wherein he described his experience in the afterlife before coming back out and into consciousness.

Many believed his theories on the basis that he had worked as a doctor for nearly two decades before a spontaneous case of E. coli caused his coma, but further questions are now being asked about his credentials.
