Stan Milford is a Navajo Ranger who spent more than a decade investigating paranormal activities. Milford says he examined hauntings, witchcraft and skinwalkers. He also looked into reports involving dozens of witnesses who claim to have seen a creature known as Bigfoot on the Navajo reservation, an area of 27,000 miles that runs through 4 states. Milford says he took the reports of all these incidents seriously and understands that the people who experience them can be deeply affected by what they’ve seen. Milford, who describes himself and his partner as a real-life X-files team, talked about what might be other dimensions on the Netflix series Unsolved Mysteries. And he’s written a book about a lifetime of mysterious occurrences called The Paranormal Ranger.
