Her own father says she “....lives in a fantasy world”, so it’s entirely possible she’s delusional. Of course, the cops have to check it out, but unless some physical evidence turns up to corroborate her story, I think LE is gonna be less than happy for being sent on an interstate wild goose chase at the suggestion of a headcase.
We can only guess at what SATAN promised her for all that murder and mayhem. Whatever the promise, it will cost her the ULTIMATE price: her immortal soul.
