You are assuming BO got his SSN Before '72. He was 11 in '72. Back then you didn't get one until you started having an income. They were not required for dependents until the mid '80s.
But nice try.
at that SSN site it says
” Note: One should not make too much of the “geographical code.” It is not meant to be any kind of useable geographical information. The numbering scheme was designed in 1936 (before computers) to make it easier for SSA to store the applications in our files in Baltimore since the files were organized by regions as well as alphabetically. It was really just a bookkeeping device for our own internal use and was never intended to be anything more than that.”
Having a CT assigned SSN by itself means nothing. We don’t know when he applied for a SSN. And if it was after 1972 he or a family member could have requested it while in CT. I find this odd and worth investigating by someone but by itself not conclusive evidence of a crime.
