I'm seven pages behind and this is so sad. If she did something that caused his death that's horrible. If she took him alive and left him somewhere by himself, then there are no words. I really believe something happened at home, inside the house. Especially, if carpet was replaced or pieced. It is possible to get that done in a day. I had experience once with a bottle of nail polish that my little boy got ahold of. After trying everything I could think of, I called the carpet dealer and they were there in about an hour. They pieced it and it looked perfect. Nobody else would have ever known.
