The Biggest Lauren Spierer Theories: What Really Happened?

Amid the ongoing investigation, Jay Rosenbaum, who was the last known person to see Lauren Spierer alive, cooperated with authorities and consented to take a polygraph examination — which IndyStar reports his attorneys said he passed.

By early 2012, the reward offered for information in the case was increased to $250,000. Although the bodies of several women were found in the months and years after Spierer vanished, they were all excluded.

Fox59 reports the searches were eventually called off and the tips dwindled. However, authorities are hesitant to declare it a cold case. Chief Michael Diekhoff said, "Many times we are asked if Lauren's case is a cold case, and our answer is an unequivocal 'no'"

Spierer's parents contend Jay Rosenbaum, Corey Rossman, and Kilroys' Sports Bar, were all negligent on the morning she vanished. In their opinion, Rosenbaum, Rossman, and the bar's staff knew Spierer was intoxicated and had a "duty of care" to make sure she was safe.

As reported by IndyStar, the Spierers eventually filed a civil negligence lawsuit against Rosenbaum and Rossman. However, the lawsuit was dismissed, as the court determined "they have failed to present sufficient evidence that [they] were at fault for Lauren's disappearance."

There are three prevailing theories as to what may have actually happened to Spierers. As reported by Talk Murder to Me, most people believe the 20-year-old student was abducted by a stranger. However, there are several other possibilities.
