Do you think then that the killing was all said and done within 43 seconds? Because that is how long we're told that the video recording was. We are also told by LE that the kids were found where they were killed. If so, how'd he get them to the killing area in that time frame? Also, who shut off the recording, or why did it shut off once everything was said and done? I'm not sure I believe that it was all caught on the recording unless somehow there is more than one audio / video recording.LE has implied or said that the audio recording from Libby's phone was continuous from the "down the hill" order until the murders were committed. So, whoever BG guy was, he was the guy who took them to the crime scene and killed them. If BG was not the killer, LE would know it from the recording. Since early days after the murder, LE has said that BG was the killer.
