Things happening out of the immediate presence of the accused could mean any number of things. Their might be accomplices, as it is well known that Witches often form Covens, or their might be diabolical aid involved.
Or an unrelated coven of witches, a single witch, or diabolical forces working independently of a group or single witch might be responsible.
Why this would be might involve a number of nefarious reasons. Maybe they intend to throw suspicion away from themselves, or some other obscure reason that makes sense only to them.
Virtually the entire populace has seen obviously unnatural activity however, and some of it might be construed as "Witchy". Dancing naked in the night would be, and gathering unusual herbs and unwholesome items with no use in goodly foods, having a cat (devilish animals, to be sure, black or not, full of lustful fornication and murderous spirit and sloth). To be clear, are there any other things divers persons may have observed in relation to the accused?
