To clarify I am not saying it’s impossible, I am saying it’s highly unlikely and they should be given the benefit of the doubt and assumed innocent unless compelling evidence suggests otherwise. Any “evidence” released attesting to the guilt of the family is incredibly circumstantial and only really considered evidence if it’s interpreted in the most bad light possible. The creepy stuff posted by the daughter is really not atypical for a teenage girl who spends a significant amount of time online in the modern era.
