In all the interviews and calls that have come through so far, there are none for the guys that pushed the car. I think these guys are the invisible men. I don't believe they exist. These two guys would be very important to find if they were real. They could provide plenty of information about the time, the smell of the car and Casey's demeanor. I just don't believe they are real.
I think someone else was there. A friend that Casey called. She called JG to try and have him come pick her up. She called Tony and he finally did, with what sounds like some reluctance. Why couldn't she have called another on that day? I hope the phone records show this.
Here's something else to add to that.
The tow yard guy didn't have a key, so Casey didn't leave the key in the car. She pulled into the parking lot and just abandoned the vehicle claiming it ran out of gas.
From what I recall, when George got to the tow yard, he didn't put a key in the ignition and start it to see that it was out of gas, he just went directly to his vehicle and got gas cans and began putting gas into the car.
Who knew it would be out of gas? How did he know to bring those gas cans to the tow yard? Lucky guess? Maybe... But from that, now there seems no proof that the car was out of gas?
It looks to me like the entire family plants seeds for one another and they each run with whatever sounds good.
