On Tuesday, a jury from the Erath County District Court found Eddie Ray Routh guilty for the murder of Chris Kyle, the inspiration for the Clint Eastwood-directed film American Sniper.
The ex-Marine was sentenced to life in prison without the possibility of parole. Prosecutors did not seek the death penalty.
In February 2013, the 27-year-old shot Kyle and Chad Littlefield at the Rough Creek Lodge and Resort's shooting range in Texas.
The former member of the Marine Corps had pleaded not guilty by reason of insanity, claiming he was under psychosis when he released fire on the Navy Seal and his friend. A veteran of the Iraq war, he had been diagnosed with schizophrenia since becoming a soldier.
