One of the most inhuman killers was operating out of the Detroit area between February and October 1975. In that time seven young women, all living on low wages or working on the street were raped and murdered in the Cass Corridor neighborhood. Witnesses state that the killer drove a beige Oldsmobile and offered his victims $15 in exchange for sexual services before threatening the women with a knife before having his way with them and strangling them.

The unknown assailant became known as "Bigfoot" because of his immense stature. Even with all of this information available to the public only one suspect was ever named in the case, 29-year-old Carl Mayweather Jr., who was arrested in 1976 following an attempted rape of a woman. Even though his M.O. was similar to that of the Bigfoot Killer he had a solid alibi and no further charges were pressed. The case remains unsolved to this day.

Everyone at the Brodhaven Primary School saw a huge flying saucer

On February 4, 1977, a yellow cigar-shaped craft allegedly landed next to the Brodhaven Primary School. A class of 14 students claimed to observe the craft's landing as well as a silver creature moving about the ship. On February 17 of the same year teachers at the school claimed to have seen the exact same UFO making the rounds of the school. If that was all that happened we'd still be fascinated, but two months later the proprietor of the Haven Fort Hotel in Little Haven alleged that he noticed an "upside down saucer" in a nearby field and two humanoid creatures were piloting the crazy, mixed up ship. To this day no one has been able to prove or disprove these sightings, but pinning the claims on a prankster seems a bit light.
