Eddie Ray Routh, the convicted killer of Chris Kyle and Chad Littlefield, was transferred to a state prison in Abilene Friday, March 6.

The former marine will be held in Abilene's Middleton Unit for a 30-day mental and physical evaluation before being assigned to a permanent unit, reported WFAA out of Dallas.

Jurors in the Stephenville, Texas, trial rejected the insanity claims posited by Routh's defense after two hours of deliberation in February.

One week after the conclusion of the trial Routh's attorneys filed an appeal.
