Happy Halloween! Buckle up for some creepy-ass, true crime history, my friends.

This 1895 house was the home of Sacramento, California’s notorious serial killer, Dorothea Puente.

Seemingly a sweet, old lady with a large and a helpful heart, Puente ran a boarding house in this Victorian cutie, caring for people who were older, sick, or without a home.

But it turns out, she was also poisoning them in order to embezzle money from their social security checks. At least nine people are believed to have been murdered here between 1982-1988, with seven of them found buried IN THE YARD. Which, as you can see, is not that big. A few people may have been buried alive, and one was even dismembered — the missing body parts never recovered.

Once Puente was finally caught and tried for her crimes, she was convicted of three of the murders; the jury deadlocked on six others. She received two life sentences and died in prison in 2011 at the age of 82.

This is honestly much too long and detailed of a story to get into here, but if you’re curious as to how she got away with this for so long, there are tons of articles online. Or, if you really want to go down a rabbit hole like we did, check out the intriguing two-part show, “Murders at the Boarding House,” on Oxygen, which is available On Demand.

As for the house, a couple bought it at public auction in 2015 for $215,000. The owners were fully aware of its history, but try to be a bit playful about it. According to Oxygen, they have a mannequin with a pink coat and gray wig staged with a shovel in the backyard.

Numerous signs on the property embrace its gruesome history. “Trespassers will be drugged and buried in the yard” and “The House is Innocent” are just a few signs you’ll find here.

The Puente house was also featured in an episode of “Ghost Adventures” because of reported paranormal activity, but we couldn’t finish watching the episode because the host grates on my last nerve.
