Factual error: After Hamby shot the male police officer, the female officer shot at Hamby and Hamby tilted his upper body to the left to avoid being hit by the bullet. Given the speed at which a bullet fires, there's no way Hamby would be able to see it coming at him or be able to dodge a bullet aimed toward him. (01:06:35)
Factual error: Hamby apparently spent three nights in the hole. There were snow flurries and a coating of snow on the ground each day but it reached 43° F on day 2; overnight temperatures are typically 20-30° colder than daytime temperatures. Joey brought Hamby a sleeping bag the second night. The next day, Joey told Hamby he'd bring him some blankets, and Hamby pointed out that his sleeping bag was "wet already." This prolonged exposure to cold weather was enough to cause hypothermia but Hamby was fine.
Factual error: The manner in which "Hamby" fell into the hole (or well) did not reflect physics or reality. He was running/chasing Joey and Matt. Whenever one walks or runs, one's feet are never straight down together (like standing), so only one foot could have been over the hole or failed to clear it. Hamby should have tripped and fallen over (face forward) with his upper body landing past the hole. This should have kept him from falling straight down into the hole (as if dropped from above the hole).
