IIRc it was text messages between Casey and Amy,when Casey "left" her car there TL picked her up, and he stated that she was outside of the car waiting for him, and told him that her dad would pick it up and take it to the shop. Casey tried to get Amy to get gas cans for her on the 29th, and Amy was busy. She and Amy went to get gas cans on the 30th, but Casey hung out with Amy the rest of the day. So why not have Amy take her to the car, or did Amy know it was at Amscot, that I don't know. So when she does go after Amy went to work, Puff the car is gone, (would love to have been a fly in TL's jeep with her)so was she going to put gas in the car and some how come back and get it later, or maybe just move to keep it from being towed. That is the question, what was she going to do.
