Cynthia Anderson was a 20-year-old legal secretary from Toledo, Ohio, who was raised in a religious household. Despite her strict upbringing, she had a boyfriend and was preparing to attend Bible College. The previous year, she had seen graffiti outside her office window that read "I Love You Cindy" with "by GW" in the corner. That summer, she was being harassed by anonymous phone calls and experiencing nightmares about being attacked.

On August 4, 1981, Cynthia left for work as usual but was reported missing when her employer found the office empty with the scent of nail polish remover in the air. There were no signs of struggle, but her keys and purse were missing, and a romance novel was left open at her desk to a page where the protagonist was abducted. Her case remains unsolved.

In 1920, a man driving a cart with an old horse stopped outside the U.S. Assay Office on Wall Street in New York City across the street from the J.P. Morgan building. He got down from the cart and disappeared into the crowd. Minutes later, the cart exploded, killing over 30 people and injuring 300 more.

At first, authorities believed the explosion was an accident, but it was later discovered to be an intentional act of terrorism. The New York Police and Fire Departments, the Bureau of Investigation, and the U.S. Secret Service investigated the incident but could not find the perpetrator. The only lead was from flyers found in the area before the explosion, demanding the release of political prisoners.

Authorities suspected followers of the Italian Anarchist Luigi Galleani, but the case couldn't be proved, and Galleani had already fled the country. Over the next three years, investigators pursued leads but were unable to identify the bombers. The case remains unsolved to this day.
