Another "Occupation" that comes to mind;
student. Although I am not completely on board with this idea, I must consider the age range and information stated at the last PC (18-40)- which is also listed on the FBI posters. We know that the local school system did not have classes. We know that the MHB was a local hangout for teens at the time of the murders. We know that investigators believe the perpetrator was local and knew the area well. We also know that Libby was interested in forensics, and attended courses at Purdue University (which has several students on the higher end of the age range).
This would make BG between the ages of 16 - 38 at the time of the murders (if accurate). While I believe it was necessary for the perpetrator to have strength and stamina, would someone at the lower end of the age range have the courage (and rage) necessary to pull off a double murder in broad daylight? Perhaps someone without wisdom (immature), overly self-confident, and reckless? Kids act before they think. Could this be the reason LE has stated the public will be shocked when BG's identity is revealed? Who would suspect a kid-especially a local one who may have grown up with the girls?
Again- I am not necessarily leaning in this direction. However; it is growing increasingly difficult for me to understand a random, unplanned, opportunistic crime for no reason. But at this point, I have to believe
anything is possible. Keeps my hope alive!
