It's Thursday, October 11th, 1923, and the Southern Pacific Railroad Train No. 13 is slowly ascending the Siskiyou Mountains south of Ashland, Oregon, en route to San Francisco from Portland. The train reaches the top of Siskiyou Pass, and as it enters the 3,100-foot+ "Tunnel 13", the train has a couple of unwanted guests hop aboard.
Ray, Roy, and Hugh Deautremont were three brothers tired of pinching pennies in logging camps, and they'd read one too many books about Jesse James. This was their moment to make it rich, or so they thought.
After getting the train engineer, Sidney Lloyd Bates, to stop the train inside the tunnel, Ray and Hugh made their way to the train's mail coach, which they expected to be full of valuables. The problem was that the postal clerk, Elvyn Dougherty, saw the robbers coming and locked himself inside the mail car with the valuables. These mail cars were the historic equivalent of a "Brink's Truck", meaning no one could get inside them easily if they were locked.
But the Deautremont Brothers had a feeling this would happen, so they brought a bunch of dynamite for the job. The problem was that none of them had experience with dynamite and didn't know how much they needed to use. So they figured it'd be better to be safe than sorry and use it all; they didn't have time to measure it out.
The brothers blew the entire mail coach to bits, with Elvyn Dougherty inside. Anything of value was instantly gone, and they couldn't see anything through the steam, smoke, and utter destruction.
Panicked, the brothers decided to cut their losses and escape with absolutely nothing of value, but not before they murdered every witness, including Engineer Sidney Lloyd Bates, Fireman Marvin Seng, and Brakeman Coyl Johnson, who stumbled across the brothers as he was investigating the sound of the explosion.
The train hold-up would go down as the deadliest in history.
Years would pass without the De'Autremont Brothers ever facing justice. In fact, the case was cracked by Edward Heinrich, a man who was known as "America's Sherlock Holmes." A man who opened the first private crime lab in the USA and invented a lot of the forensic techniques still used today.
If you want the full story, I created a YouTube Deep Dive where I filmed at Tunnel 13, then added documents and pictures from the time to tell the story in what I believe is the most engaging video available on the topic. Here is the link: https://youtu.be/61IK-dV7OjE
