losing consciousness in the crash. sanjay gupta, our chief medical correspondent. i want to read to you what the attorney had to say about his memory. he does not remember pulling the emergency break. we know it was inl fact deployed. the next thing he remembers is getting his back andcology calling 911. so, is is it possible for him to remember all of that but not the derailment and how it happened? it is possible. and of course weir rer going by what his lawyer said there but there s post traumatic amnessau. you think of it as forgetting things in the past but there s also ant rograde amnessau.
