A grand jury has declined to indict the driver of a parade float involved in a train collision that killed four U.S. military veterans.
The panel decided Wednesday that Dale Andrew Hayden won't face charges in the Nov. 15 accident in West Texas that killed four veterans who had served in Iraq and Afghanistan.
The flatbed truck Hayden was driving was hit by a Union Pacific train traveling at 62 mph. The truck was the second float in a parade organized to honor wounded veterans and their wives.
The National Transportation Safety Board is investigating the accident.
Union Pacific Corp. said in December that it was adjusting the timing of the crossing signal where the collision occurred.
