Hello fellow members and guests. I am newbie here, but I have been following the case closely since its inception. I enjoy reading what everyone says and I have learned a lot from you guys. Disclaimer, the following is all IMO.
I dont have much of a background in law or crime, but I have had experience in psychology and sociology in the past. I was introduced to crime in the famous movie Silence of the Lambs. In this case, I think it is good to go back to the beginning.
What is it that the BG sought? What was his purpose for doing this? He could have been anywhere that day but he chose that location. Could it have been the location, or was it that he had targeted one of them from a past encounter? The girls didnt know him because LG recorded him. If she knew him, she would have said his name at some point. LE would have heard this as well since they have the video and the case would be a lot further along. But, he could have seen them somewhere else. Perhaps, there in earlier days. Does anyone know how often the girls went there? When was the last time?
The physical description of the BG has been discussed thoroughly, so I will focus on the voice.
The BG had a cold, commanding type voice. The words came off as though he was not out of control, but that he was in charge and in command of the situation. He had the presence of an older man that wasnt afraid of what he had coming. He had sought this out.
I do think he is, more likely than not, to be in his 40s. This crime required the energy of someone younger and in better shape than RL. The scary part is that he did this so well with only one slip up that we know about being the phone/video evidence. Although, assuming he didnt fool with the phones, LE had no way of tracking him and they didnt get any fingerprints from him off the phones.
