no earlier than 10:25 a.m. so was it samira? the detectives were baffled. having checked the security gate cameras, they knew adam had, as he told them, left the house with the two kids around 8:00 that morning. and if the woman the neighbor saw was samira, that meant she was still alive when adam left and for a couple hours after. and if that person was telling the truth or it was accurate, your guy couldn t have done the crime? that s correct. reporter: and then there was another possibility, that the woman in the driveway wasn t samira at all, it was someone else entirely. and if that was true, the woman the neighbor saw, might have been the killer. so what did you do about it? for me, it was try to figure out who it is he saw. was he one, was he in the right driveway? two, could it have been somebody else?
