Hi, my name is Angelica, and a fun fact about me is that I activate like the Winter Soldier if I hear the words "unsolved mystery" said anywhere in the same vicinity as me. It really doesn't matter what the topic is — from historical mysteries, to true crime cold cases, to things we may never understand about space, I am locked in, ready to listen, and will probably end up in a Wikipedia rabbit hole about it later. All that being said, I have also become, like, a living, breathing list of fun (and not-so-fun) facts about all kinds of mysteries.

Whether I discovered them through podcast episodes, Twitter threads, Discovery Channel shows from the 2000s, or BuzzFeed readers like you, I decided to share 13 unsolved mysteries I simply cannot get out of my mind. Without further ado, here they are:

On December 10, 1978, Mary Stuart and her two daughters, Fannie and Jessie, left their home in Honeydew, California, for a day of errands — specifically, grocery shopping, to get their TV repaired, and the optometrist. The three did not make it home that night, so one of Mary's friends reported them missing. Police checked with local optometrists and TV repair places, asking if they'd seen the Stuart girls, but none had. Almost a month later, their car was found on an old logging road just a few miles from their home. Detectives found their bags of groceries and a now-repaired TV inside and noticed the car's gas line was broken. There was no sign of the family, nor were there indications of foul play.
