Chris Kyle is the author of American Sniper
. Chris has been credited with the most kills of any sniper in the history of America. He once shot someone from over a mile away. Since he retired from the military, Chris spent most of his time with his wife trying to help veterans who were suffering from PTSD and working for a foundation to help such veterans. Yesterday Chris and one of his friends took a former solider suffering from PTSD to a gun range. At the range the soldier turned on Chris and his friend and killed them at point blank range. He then led police on a chase before finally being caught.
