Im starting to wonder if one of the vehicles at CR1s was used to drive to the other scenes. IF they drove one of CR1s vehicles, that would make them even less suspecting if that vehicle was seen at the other locations.
This is just a theory and only that, but it would make sense. Also speculating that KR didnt have amenities such as running water at his camper, its my new theory that he was killed because the killers expected him to arrive at CR1s that morning to shower before work. They didnt want to chance KR interrupting them. Im sure KR had a water holding tank, but if youre living in a camper, hauling water and filling up tanks would be a pain, so Id imagine a person would try to conserve.
Maybe KR was known to go to CR1s in the morning before work? Also, its my belief these killers somehow knew that KR was supposed to have an overnight guest and would have his door unlocked, allowing them access to his camper.
That could be how the killers got in Danas as well. If she saw a car pull in that looked like Chris, why wouldnt she open the door?
