Security camera footage shows action happening on 5/21/18 at the same time that Charles Wright is doing his live Saturday night podcast and kids are at a Saturday night party. May 21st was a Monday in 2018.
Scenes happening from 6pm and later on May 21st in Green Bay show full dark skies outside. Sunset in Green Bay on May 21st is about 8:20 p.m.
It's kind of a plot hole to make a "found footage" film without stating who found and edited the footage.
