I think it was leads from folks other than LE - rumors maybe. Maybe a PI? Who knows.
By the way, Monday night I had dinner at Fireside Pies in the Shops at Legacy and we parked in the same garage not far from where CM parked that night. There is a dumpster less than 50 yards (behind the dunkin donuts) from where her car was parked - I don't know what the access to it is (open or secure) but it did make me wonder. 4 days later on a holiday weekend, that trash could have definitely been picked up - especially on Tuesday when she wasn't reported missing until Tuesday night. I always wonder if LE checked the landfills. The lighting and type of location makes it seem unlikely that a perp would dump a body there, but you just never know. I didn't want to walk over to it because there was some sort of commercial vehicle blocking it (doing something else, unrelated to the dumpster).
Additionally, that parking garage and general area is fairly immaculate every time I've gone over there. If there were lost items (shoe, earring, etc) as a sign of a struggle, I'm 99% sure they would have been swept up and dumped by the time anyone went looking for her. Now, it it were something more valuable - phone, keys, etc - hopefully they have a lost and found those would be turned into.
Just thinking...
