For the second time since his arrest in February, Eddie Routh, the man suspected in the shooting deaths of Chris Kyle and Chad Littlefield, appeared in court Monday.

Because of security concerns, Routh was escorted by a long line of law enforcement officials who ushered him through back doors. Police officers were stationed at various intersections surrounding the courthouse.

Security inside the courtroom was equally tight. Judge Jason Cashon prohibited cell phones, cameras and bags from being brought inside the courtroom, and spectators and journalists were required to enter through metal detectors.

Despite the hoopla, the hearing was over in a matter of minutes.

Routh was ushered inside the courtroom sporting a thick beard and glasses. Flanked by his attorneys, Shay Isham and Warren St. John, Routh never said a word.

St. John told the court the defense is reviewing between 5,000 and 6,000 pages of discovery and crime scene photos, calling it a "slow and tedious process."

Routh is accused of shooting and killing Kyle and Littlefield at a gun range at Rough Creek Lodge on Feb. 2.

The trial is tentatively scheduled to begin Oct. 21.

Cashon told the defense he would consider postponing the date if they need more time to prepare.
