When it comes to ghost hunting, the most interesting spirits to track down are the angry ones. Sure, they might be capable of injuring you, but they also tend to be the most active. Take, for example, this footage from the 3 Girls In The Dark paranormal team. The group explored the famous Villisca Murder House in Iowa late last year and captured some bizarre footage.

In 1912, the house was the site of a brutal murder that left all six members of the Moore family and their two young guests dead. It was after midnight when one member of the team recited the phrase that evidently inspired Reverend Lyn George Kelly to commit the murders. After the women said the phrase aloud, one of their cameras started shaking violently. That ghost wanted nothing to do with being taunted by the living.

It’s worth noting that even though Kelly confessed to the murders in 1917, he was never actually convicted. His case went to court twice, and both times, he was acquitted. The murders remain officially unsolved to this day.
