The Jamison Family Disappearance (Oklahoma, 2009)

A family of three mysteriously vanishes while looking at rural property, leaving behind their truck containing their IDs, phones, $32,000 in cash, and their hungry dog. Their bodies were found four years later, but their deaths remain unexplained. Security footage from their home showed them acting strangely in the days before they disappeared, loading their truck in an almost trance-like state.
