Kyle, 38, and his friend Chad Littlefield, 35, who was also killed, took Routh to the firing range for therapeutic purposes. They were dead when officers responded to a 911 call. Prior to his death, Kyle was involved in helping former troops suffering from PTSD.

Defense attorneys for Routh said he had a long history of mental illness, however, prosecutors dismissed that claim saying that Routh knew the difference between right and wrong.  Jurors had three choices of guilty, not guilty or not guilty by reason of insanity.

The film won an Oscar for best sound editing on Sunday. Pic was based on Kyle’s bestselling book.  Kyle is known as the deadliest sniper in U.S. history with 160 confirmed kills in Iraq.
