The intense heat may be behind the death of a man in Nuevo Laredo. Yesterday afternoon a man was seen falling from a train about 500 yards from Mexico Highway Number Two. When informed of what had just happened, the train's engineer brought the locomotive to a full stop and rushed to aid the fallen man. The unidentified man was unresponsive and appeared to be suffering from dehydration and heat stroke. Efforts were made to dehydrate the man with a canteen of water but he died moments later. Nuevo Laredo officials believe he was a migrant. The man had no identification. Officials say he appears to be about thirty or forty years old.
