Several years ago, when I was in El Paso TX, an illegal was struck and killed by a semi-truck while running across I-10. Two days later, I was in Phoenix and they found a human arm on the highway that they connected to the fatal hit-n-run in El Paso two days earlier.
Last year there was a fellow riding a bicycle down the shoulder on AR-67... log truck went passed him and the wind sucked the guy up under the trailer. Killed him on the spot, driver never knew it until the Sherriff Dept. caught up to him about 50-60 miles away.
