Most Terrifying Things About America’s First Serial Killer

Every Room Had Special, Extra-Creepy Features

In modern times, most hotel rooms have a bed, a TV, and a bathroom. Anything else would be considered an upgrade. If you checked into Holmes’ murder hotel, you got a few extra features you didn’t know you were going to end up paying for in the cruelest most horrifying way.

Each bedroom in the expansive hotel was soundproofed and also had a gas line that was controlled from the other side of a wall. One could assume this was used to kill people with carbon monoxide poisoning or some other kind of way to essentially gas people. Doors within the hotel had silent alarms that tracked movement, so Holmes could know the whereabouts of each guest at any given time. If his terrifying invention wasn’t so terribly evil, it is rather amazing what he was able to accomplish during this time period.
