The long-awaited trial of the man accused of killing Chris Kyle, author of the book American Sniper and subject of the movie with the same, and his friend Chad Littlefield will finally begin today - a little more than two years after the crime took place.

Routh is accused of killing both men at a gun range at Rough Creek Lodge. Today marks what would have been Littlefield's 38th birthday.

Opening arguments in the capital murder trial will begin at 9 a.m. this morning at the Donald R. Justice Center. A jury of 10 women and two men are set to hear the case, which is expected to last about two weeks.

Kyle's widow, Taya Kyle, and Littlefield's mom, Judy Littlefield, are expected to be the state's first witnesses.

Routh's attorneys, Warren St. John and Shay Isham, are expected to take on an insanity defense.

The E-T will have several reporters on scene during the duration of the trial. Look for updates throughout the day online at yourstephenvilletx.com and in each edition of the Empire-Tribune.
