I checked many sites for GB and crossed his name and JoAnn's name also with residences. I firmly believe he is 60. If you look at one of pics from FB there is a pic of him (GB) with 2 little girls and a woman holding a baby. I don't think it was JoAnn, but his daughter holding her daughter, as the baby is too young to be JoAnn's youngest. IMO. Check Intelius, Veromi, Zabasearch, 123people.com & Radaris. Also the map I linked with their residences. LE has stated AM is a "friend" of the family, so it's safe to assume he is not GB's son.
I'm thinking from the pics, AM (PR) has been out to AZ with them at some time.
I want to know what kind of business or hobby GB had for his "shop" he had in TN. And finally what I REALLY want to know is......did AM have access to a vehicle....other than a motorcycle....and if so WHAT KIND?!!!! I'm NM and if they headed west to AZ, then there is a good likelihood they took I-40 all the way out...and just might go thru here.
FBI is involved because of AZ or MS possibilities.
Request: if stating info is from FB, please reference it so we don't get it mixed up with MSM. TIA
