From the Orlando Sentinel:
July 15, Tuesday. The car found abandoned is picked up by the Anthony family from the wrecker company. Simon Birch, manager at the wrecker yard, noticed the stench coming from the vehicle both on June 30 when it was originally towed, and when he brought it up to George Anthony. They left and he picked up the car several hours later. One tow lot employee overheard him say something to the effect of his daughter wouldn't let him see his granddaughter, and the tow guy who went to the car with him was told his daughter HAD been missing but his granddaughter was still missing. They get to the car, and open it and tow guy says it smells horrible
met with TOTAL silence from George. They opened the trunk and flies flew out and they find a bag of trash with some pizza and some maggots, etc.; the bag is thrown into the front of a dumpster at the tow yard, by the tow guy BUT it WAS collected into evidence from there George sees the gas gauge is on empty and says, oh, I have gas in my car. The only time we hear of the car being out of gas is from Casey's statement that it was pushed into the lot because it was out of gas. He puts in gas and leaves. George said the smell of decomposition was so bad they drove home with all the windows open.
