In his book, Alexander claims that when he was in a coma caused by E. coli bacterial meningitis, he went to heaven. Of course, Dittrich's piece is not the first time that Alexander's text has come into question. In April, Michael Shermer at Scientific American explained how the author's "evidence is proof of hallucination, not heaven." But Dittrich calls into question not what Alexander experienced so much how he did. While Dittrich looks at legal troubles Alexander had during his time practicing neurosurgery, perhaps the most damning piece of testimony comes from a doctor who was on duty in the ER when Alexander arrived in 2008. Dr. Laura Potter explains that she "had to make the decision to just place him in a chemically induced coma." But that's not how Alexander tells it, according to the Esquire investigation.
