essential events that follow a sudden death. that funeral must have been -- i don't know. >> the funeral was horrible because we were in shock, and we had to hold up. i don't remember much, but i do remember nanette sitting in the front with each child on either end, and they were both bawling at the top of their lungs. and then i remember my brother speaking, too, at the funeral and telling everybody what an amazing man he was and what a great dad he was for him. >> reporter: bill's girlfriend nanette moved out of the house bill was killed in to another house he owned on the beach. kim and her husband move back into the family home with her brother. they clung to each other for dear life. >> we cried on each other's shoulders and did a lot of counseling and therapy and grieving. >> reporter: what made it worse was they didn't know who did it. or why. any more than did the newport beach police. when a thing like this happens, i mean, it's really an execution-style killing. this was obviously someone who intended to kill your dad. you must immediately wonder who.
