History Detectives Season 7 Episode 3 St. Valentine's Day Massacre/Booth Letter/Cemetery Alarm

In the third episode of the seventh season of History Detectives, the team sets out to investigate three intriguing and very different historical mysteries. First, they dive into the infamous St. Valentine's Day Massacre, one of the most notorious gangland shootings in American history. Using modern forensic science techniques and expert testimony, they try to shed light on the unsolved case and determine who was really responsible for the 1929 massacre. The detectives explore countless leads, including the role of the Prohibition era gangster Al Capone, and examine the possible motives and conspiracy theories that abound around the event.

Next, the team turns their attention to an intriguing letter attributed to the infamous assassin John Wilkes Booth. The letter purports to be written by Booth just before he was killed and claims that there was a larger plot to assassinate multiple high-ranking government officials on the night of Lincoln's death. But is the letter authentic, or just a clever forgery? The detectives explore the handwriting, paper, and context of the letter to determine whether it is a genuine historical artifact or a modern hoax.

Finally, the team investigates an unusual artifact from a local cemetery - a mysterious metal box equipped with an alarm system. The box has long been associated with a local legend about grave robbers trying to steal bodies from the cemetery, but no one knows for certain what it was really used for. The detectives explore the history of the cemetery and its surrounding community in order to determine the box's true origin and significance.

As always, the detectives use the latest scientific and historical evidence to get to the bottom of each mystery, relying on their expertise in areas like forensic science, history, and archeology to unravel the secrets of the past. Along the way, they engage with experts, witnesses, and other historical figures who help piece together the stories behind each artifact. With each mystery they solve, the detectives shed new light on the events and people that shaped our world, showing how even the most obscure artifacts can unlock big pieces of history.
