On Wednesday, Nov. 24, 1971, a mysteriously normal man named Daniel Cooper bought a one-way ticket on Northwest Airlines from Portland, Oregon to Seattle, Washington. He was in his mid-40s, wore a suit, an overcoat, brown shoes, a white shirt, and a black tie. He carried a briefcase and a brown paper bag. Before takeoff, he ordered a drink and gave a note to a flight attendant saying he had a bomb.

The note demanded $200,000 in cash, four parachutes, and a fuel truck to refuel the plane. After the demands were met, Cooper let some passengers and crew off the plane but kept some on board. During the flight, he put on sunglasses and then jumped out of the plane with two parachutes and the money. He was never found.

Despite years of searching, authorities have not been able to identify Cooper or find out what happened to him. The case is still considered one of the greatest mysteries in the history of the FBI and the United States.

In 1972, a decomposing forearm was found by a dog in Springfield, New Jersey. Police were alerted and soon discovered the body of 16-year-old Jeanette DePalmer atop a nearby cliff, after she had been missing for six weeks. The Satanic panic grew in the community as the hill where she was found was covered with occult symbols, leading many to believe that her body was placed on a makeshift altar. Some pointed fingers at an alleged coven of witches, while others suspected a Satanic group. Due to a flood, many details of the case were destroyed, but it was reported that the cause of death could not be determined due to the body's decomposition. A local homeless man was investigated but cleared of any connection to the killing. It was speculated that DePalma may have provoked a group of Satan-worshipping teens at her high school. Her death remains unsolved to this day.
