The BIL said that the dog was asleep in the 4 year old’s room.One thing that is really telling to me is the dog. Almost any dog (especially a golden doodle!) is going to bark if someone enters the house late at night. Yet apparently they didn’t get out of bed to check. This says to me that either 1) they were used to someone coming and going (maybe a basement guest?) or 2) the perp was already inside the house, whether invited or not.
