I have worked at dealerships. When you check your car in at the dealer. Usually there is a “lot boy” who parks the car out in service lot after check in, it is not uncommon for a mechanic to come and look at a car during check in to get more info on what needs to happen with a car and let the service writer know. I have done that before. Sounds to me like the lot boy was supposed to move the car but, didn’t know how, and didn’t say, and then, because of his incompetency killed the other guy.
