If I have this correctly, Casey has always lived with her parents. Except that in June she took off for awhile with Caylee. While gone, Casey called everyday so they knew she was OK. Grandma would ask to talk to Caylee and got excuses, like she’s napping, she’s with the sitter, etc.
Recently Casey went back home, without Caylee. That’s when Grandma started to get really suspicious. She and her husband initially told the police that they feared something had happened to Caylee but now Grandma has gone into some kind of denial.
