I agree with your take on the situation. If a senator received this information and, upon further inquiry, found out it was already under investigation what were they suppose to do?

When I was in college I spent a summer taking some classes at Georgetown and worked as an intern for a large trade organization. One of my responsibilities was to do a constituent mail survey to determine how much weight members of congress gave to such mail. IIRC they pretty much ignored mail from non-constituents. In addition, the volume of mail they receive is astounding (and that was long before email). It is very possible that if they were aware the military was looking into this situation they would respond in a form letter that the military was in charge.
