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 1996, a ransom note for 6-year-old JonBenét Ramsey was discovered by her mother, Patsy Ramsey, on the back staircase inside their Boulder, Colorado home. Patsy immediately called the police to report JonBenét missing. However, less than eight hours later, JonBenét’s body was found by her father, John, in the basement utility room of the house. Duct tape was found across her mouth, and a cord was wrapped around her neck. Upon arriving at the crime scene, police suspected that it had been heavily compromised due to multiple people coming and going from the house. Despite JonBenét's beauty pageant prominence and her mother's own history as a beauty queen, her death was ruled a homicide. The cause of death was asphyxia by strangulation and craniocerebral trauma. The case garnered national attention, and to this day, it remains an open investigation with the Boulder Police Department.
