In this episode, we examine the disappearance of 59-year-old Dan Davis outside Chicago after he stopped answering texts at all. Hours later he crashed his car, refused medical care, was dropped at workplace, and then walked out alone, never seen again.

Security footage shows him wandering for a day through yards and alleys, falling, circling streets, and asking for directions he should know. His apartment was left in disarray, and the last sighting came near a church before the trail went cold.
