Should We Classify Lauren Spierer's Disappearance as a Cold Case?

It has been nine months since Lauren Spierer vanished from Bloomington, Ind., without a trace. The IU fashion student was last seen during a night of drinking and partying with her friends, but disappeared in the early morning hours of June 3, 2011. The last people known to have been in her company say that she wandered home barefoot and drunk, but there has been plenty of speculation and strange behavior in this case to draw questions toward when she was truly last seen. Most suspicious are the claims of amnesia being made by Corey Rossman, one of the young men last seen with the missing woman.

Charlene Spierer has made another attempt at engaging the person or persons responsible for her daughter's mysterious disappearance. She has posted another open letter on a blog dedicated to news on Lauren Spierer. "You Know Where She Is," begins as follows:

To whom this may concern,

Thoughts on a page. You and I share unique roles; we are both insiders, forever bound by the senseless circumstances of June 3, 2011. You were with Lauren, you know what happened and you know where she is.

The letter goes on with the same heartfelt emotion that's been shared by the parents of Lauren Spierer since the day she vanished. When will they get the answers they so desperately seek? It certainly seems that investigators on this case aren't too interested in sharing any details with the public, if there are any to share. Why are they being so quiet?

Once this case reaches a year old, it could be considered a cold case by definition, but the detectives in this instance are behaving as if it has already gone cold. Yet there are tons of clues that are quite indicative that something sinister went down on the morning of June 3, 2011. For instance, the following series of enhanced images show the infamous white pickup which law enforcement cleared of suspicion early in the woman's disappearance. From the looks of this pickup, the mass in the back could in fact be observed as humanoid shapes. Nonetheless, detectives out of Bloomington have failed to address these damning images. Maybe they're hoaxed, but maybe they're not. How is anyone to know without so much as a "yay" or "nay" from law enforcement?

Charlene and Rob Spierer have been desperately trying to find their daughter, and it seems that they are finding very little help as far as the official investigation is going. Could there be a reason for this? Could the reason Bloomington investigators are staying so mum on the case have anything to do with other missing women in the surrounding regions? Some investigators and crime analysts believe that there are connections between the disappearance of Lauren Spierer and the strange cases of Holly Bobo, Paige Johnson, Katelyn Markham and murdered woman Misty B. Gwinner. One such person is Bill Warner PI, who believes that a serial predator could possibly be involved in these numerous cases of missing women in the Midwest and Southern states. If that's the case, then chances are the person or persons responsible has probably read Charlene Spierer's open letter, but will they be compassionate enough to give this family the closure they deserve?
