So I looked them up. They are thin, synthetic or woolen mixed with silk. Could be it. It would be interesting to find out who of the POIs had a Navy past, or maybe someone's family members served in the Navy? He could have grabbed something from a hanger. But the word "navy" is heard too many times to dismiss.
in one photo Abby is wearing a Navy beret, I’m not sure where to purchase something like this. Don’t believe it is military, just fashion accessory. Sorry unable to link photo.
IMO. I have often wondered if BG had stolen the items in his bulky jacket from one of the local homes.
Praying for justice for Abby and Libby!
