A train rammed into a flatbed truck carrying participants in a West Texas parade saluting U.S. troops, killing four people and injuring several others, a police spokesman said. The incident happened around 4:30 p.m. Thursday, during the "Hunt for Heroes" event in Midland. According to the group Show of Support, these festivities -- including a banquet and, after that, an "all expense paid whitetail deer hunt" -- are to honor members of all branches of the U.S. military. The last flatbed truck in the parade was crossing tracks when an eastbound train slammed into it, said Midland police spokesman Ryan Stout.
