Flag me with what you learn.
This is of interest...
Muhammad was transferred to Germany in 1990, fought in the Gulf War in 1991, returned to the United States in 1992 and got an honorable discharge from the army, as a sergeant, in 1994.
LINKI'm wondering how close Muhammad was to Hamburg. His Oregon National Guard info might also be useful.
The post previous to yours states he had a DC license. This could have his SSN; also the New Jersey car registration.
I think you need special software to access these, thought. You can't get it off the net.
