Back in Marcel's hometown, Smith meets with a man who swears Marcel confided in him about alien bodies-- something Marcel had never mentioned to the press or family. As the results come back from soil, metal and forensic handwriting analysis, Smith shares his findings with the Marcel grandchildren.
