For some of you newer WS's, after 3 years of following this case, I believe George and Cindy are nearly anal in their perfectionism regarding their home, yard, belongings, appearance, etc. They take care of their things, they are extremely orderly. Part of this issue about the gas cans is 1, Casey had been taking them without asking enough times that they 2) finally got a lock for the shed and3) hid the key from Casey. So her breaking into the shed was not just about the gas cans, but about how Casey operates. Thus the call to police. She had lost the vent/ opening one of the times she took it. So then they had to use duct tape to cover the opening. When it came back both times, he knew he had not put the tape on, because neither time was it placed as he would have had it. ( and the 2nd time it came back from LE with fingerprint dust on it)
