Well there are many possibilities and unfortunately if the focus of the investigation is narrowed down to just the boyfriends then the facts get warped to fit those theories rather than open to other possibilities as well. Also there becomes no other avenues of possible leads for instance yes all this happened but again she was a drunk girl walking alone with no shoes on at 4:30 am if she was also under the influence of anything else who knows? it could have been as simply as a total crime of opportunity. Also remember sometime ago there was a student who accidently got shocked and died in utility closet at Purdue and was missing for several months before being found. I hope for a possible positive outcome it's only been a week and it is also silly to have ten people of interest or suspects as well without anything other than wild speculation I hope it turns out well and my prayers to the family and I hope she is safely returned.
