Take the stories with a large grain of salt
The stories may be "true," but they aren't accurate. The Belle Gunness story is much more interesting than what True Nightmares decided to tell. The story this week about Linda Hazzard and Starvation Heights occurred during the early 1900s, not the early 2000s as it looked based on the cars and clothes in the show. It would have been easy enough to adjust the clothes and find a vintage car.
The stories are interesting but knowing the actual events makes it hard to enjoy this show. I just keep looking for the flaws. It takes all the entertainment out of the show.
