and it should be. >> now, in terms of what they may have known, other than the obvious of common sense and why they wouldn't talk to the petitos, why they wouldn't return the petitos' phone calls, as far as we know they may not have been lawyered up, the petitos didn't even know if gabby was missing, listen to what the lawyer said on "good morning america." >> you told us the laundries knew brian was grieving the night he left, that was on september 13. but gabby's remains weren't discovered until the 19th. why did they think he was grieving? >> brian had been extremely upset, chris and roberta were concerned about him. they expressed to me when he walked out the door that evening, they wish they could have stopped him, they wish they could have prevented him from going out but he was intent on leaching. >> look, either he didn't mean to use the word "grieving" and he just meant to say distressed.
