A central problem indicator in the trials was the use of spectral phases because the crime had to do with the deal between the devil and the people with charges of witchcraft, which may risk the devil taking the witch’s body over, and because of this there would be no witnesses, which makes the problem difficult. Spectral evidence includes the affidavit by the associated that they could detect the ghosts of the witches haunting their victims; the evil actions were not performed by the accused themselves, but by the evil spirits who seize their human form. One complication with spectral evidence was that spirits of demons were imperceptible to other people in the identical space; only the distressed girls could see the forms of the spirits.
