A former U.S. Navy SEAL sniper and best-selling author has been shot to death in Texas, allegedly by a mentally ill former Marine.
Chris Kyle wrote American Sniper, which chronicles his experiences as one of the U.S. Navy's deadliest shots. Kyle, a Navy SEAL from 1999-2009, said he killed more than 150 Iraqi insurgents and other enemies, and called himself the most lethal sniper in U.S. military history.
Former U.S. Marine Eddie Ray Routh is accused of fatally shooting Kyle and another man Saturday at a shooting range near Forth Worth, Texas.
Those who knew the victims and the suspect say Routh suffers from post traumatic stress syndrome, a mental illness that afflicts many former servicemen exposed to extremely violent conditions in combat.
They say Kyle frequently volunteered to help veterans and that he brought Routh to the shooting range as a form of therapy.
Police declined to discuss any theories about Routh's motive for gunning down Kyle and the second victim.
