The Patriot Guard Riders provided an escort and flag line for the family of fallen U.S. Army Sgt. Brian L. Walker Thursday as the family made their way to his funeral at Pentecostal Church of God. Several emergency services officers also participated in the escort, including a DPS Air Rescue helicopter. Sgt. Walker was killed in action in Afghanistan on May 13. Here, Don "All In" Helm came with seven others from Phoenix to pay their respects Thursday. The DPS helicopter flies overhead.
