A French woman embarked on a day trip to northern Italy for what appears to have been a ghost-hunting trip. She never made it home.

The body of the unnamed woman, 22, was found over the weekend in an abandoned church where she had been stabbed to death and drained of blood, according to a CNN report.

Now investigators are trying to figure out if she was TikToker who was part of a ghost-hunting stunt or if her death was something more sinister, such as a consented sacrificial death.

The woman had traveled from her hometown near Lyon, France, to La Salle in Aosta Valley, Italy, and had informed her family of plans to find a “haunted house believed to contain ghosts,” police told the outlet.

…

Witnesses in the town interviewed by police said they had noticed the woman was accompanied by a man hours before her death. Both had been dressed up as vampires, CNN reported.

One witness described the woman as “emaciated” and looked like a “walking corpse,” while the man was described as having dark hair and olive skin, the outlet added.

There was no sign of a struggle, CNN reported, though police noted that some of the blood from the floor had been removed when they arrived to inspect the scene. Police are still searching for the man who was with her, the outlet added.
