Anything is possible. I did not know about the bartender witness. I did not follow this case as it happened in June 2011. I remembered it from the news because I remember it was a big story not too long after Holly Bobo and thought I would take a look at it. If Lauren Spierer was placed outside of the apartments she left that night, why is there still so much suspicion surrounding those friends of hers? It could possibly be the same man, but as you wrote, the cameras would have picked up any vehicles circling the area that night. Wouldn't they have picked up DM's vehicle too? It seems strange too that DM would leave Hannah Graham in such an open noticeable place, yet obviously would have to have found a very good spot to hide Lauren Spierer's body(if she is deceased). And the Graham case happened in 2015, after the Spierer case. Is it possible in the Spierer case from 2011 DM did not use a car and came up with the perfect place to hide a body, yet in 2015 did use a car and left the body out in the open? Yes it is possible, but in my opinion, that is why I have a hard time believing it is probably the same man. But when you have no idea what happened anything is possible and any theory is out on the table to be discussed. I only hope someday the police will release the rest of the video surveillance from that night and let us armchair detectives take a look at it. Maybe there is something we or someone else from the Bloomington, Indiana area see that can help solve the case?
