It sounds like the child died of hypothermia, obviously armchair coroner report. Nevertheless in the later stages of hypothermia it’s common for people to start hallucinating and remove all of their clothes. This is assuming that this “camp” didn’t remove his clothing to cover up something nefarious they did to the child which, given that this Unmonitored Juvenile Detention FacilityWilderness Camp is under investigation, is just as likely.
