I just keep turning this question over and over in my mind. Who, if anybody, verified that the car was in fact, out of gas? The tow yard folks didn't have a reason to check it. They didn't have a key. Also, has anyone read anywhere verification that the gas guage is in fact faulty? I assume the authorities have gone over this car with a fine-toothed comb. IMO, this car is the actual crime scene. I just keep seeing in my mind's eye that little doll in the car seat, a silent witness.
Also where I live, when an auto is abandoned, the police come and put an orange sticker on it to signify that it has been checked for stolen status, and then the police notify a wrecker service to have the car towed in three days. I would think that tow services would want to verify the status of a car before towing it away. It's all so confusing and leaves so many questions.
