A 17-year-old girl is said to have accidentally hanged herself at a haunted house attraction in Fenton, Missouri.

Fox2Now.com reports that the girl works at the “Creepy World” haunted house, and was found hanging from a noose inside the attraction last Thursday night while customers may have possibly walked past her thinking she was one of the scrapy props.

Police say she was unconscious when she was rushed to a hospital, and as of press time Friday, she was in critical, but guarded condition.

“We noticed a bathtub was there. It appears as though the individual stood up on the sides of the bathtub and for whatever reason, put their head in this noose. It looks like her feet may have slipped,” Captain Ron Arnhart of the Jefferson county sheriff’s office said.

After the accident, part of the attraction was temporarily shut down, but officials re-opened it within a few hours.
