The night before Zak disappeared, he'd been texting his mother about plans for Christmas and was arranging his work schedule at a Super One bakery in Duluth. Investigators feel that a cellphone ping may have misled the investigation from immediately searching the grounds near where he went missing.

Joshua's father, Brian, lost a lawsuit this year to get his hands on investigative materials related to his son's case, which would have included those images, among other information provided to the Netflix series.

*Correction: In this episode, it states Rev. Tom Andert was in charge of Joshua Guimond's dorm hall. It should say Rev. Tom Andert was in charge of the dorm Joshua Guimond visited the night he went missing.
