Mr. SPECTER. If there was a high-powered rifle, or a high-powered rifle was going at a fast speed, as fast as 2,000 feet per second, which encountered only soft tissue in the body, would you have sufficient knowledge to know whether or not the appearance of that hole would be consistent with an exit wound? Miss HENCHLIFFE. Well, from some information I received in talking to someone about guns later on, they said that this is possible. But you have a small exit wound--you could have a small exit wound. Mr. SPECTER. Under what circumstances? Miss HENCHLIFFE. As you described--a very fast bullet that didn't hit anything but soft tissue going through. Mr. SPECTER. And do you have any other source of information or basis for having an opinion whether it was an entrance wound or an exit wound other than that source of information you just described, plus your general experience here at Parkland as a nurse? Miss HENCHLIFFE. No, sir. Mr. SPECTER. How long have you been at Parkland as a nurse? Miss HENCHLIFFE. Well, I have had emergency room experience for about 5 years here and a couple of years at Baylor Hospital. Mr. SPECTER. And is that the total sum of your experience? Miss HENCHLIFFE. In the emergency room. Mr. SPECTER. And what other experience have you had besides emergency room experience? Miss HENCHLIFFE. Well, in the operating room here. Mr. SPECTER. How long have you had operating room experience here? Miss HENCHLIFFE. 3 years. Mr. SPECTER. And how long have you been a registered nurse altogether? Miss HENCHLIFFE. 12 years--almost 12 years. Mr. SPECTER. And what is the source of information about the appearance of an exit wound from a high-powered gun which you have just described? Miss HENCHLIFFE. I don't remember who I was talking to now. I was just talking to someone one day about gunshots and after this report came out that said that any high-powered gun that this could happen. Mr. SPECTER. That it could be an exit wound which looked very much like an entrance wound with the missile striking nothing but soft tissue? Miss HENCHLIFFE. Yes, sir. Mr. SPECTER. Do you have anything else to add? Miss HENCHLIFFE. No. Mr. SPECTER. Thank you very much. Miss HENCHLIFFE. All right.
