On June 3, 2011, Charlene and Robert Spierer received a phone call that no parent should ever have to receive: their daughter, 20-year-old Indiana University student Lauren Spierer, was missing. Supposedly, she had spent the earliest hours of that morning incredibly intoxicated, bouncing between several friends before disappearing into the pre-dawn morning, never to be seen or heard from again.

Lauren was born on January 17, 1991.

It is not entirely known what transpired on the morning she disappeared. Based on accounts from the friends she was with and on surveillance footage captured of her in several places, however, investigators have a general idea of what transpired, up until the trail runs completely cold.

Lauren left her apartment with a friend, a man by the name of David Rohn, after midnight on June 3rd, 2011.

The duo went to the apartment of a friend of David's by the name of Jay Rosenbaum. There, they met up with Jay's neighbor, Cory Rossman.

At 1:46 a.m., Lauren and her friends arrived at Kilroy's Sports Bar.

It is unknown why Lauren was served alcohol since she was just 20 years old. Despite this, she was seen on video leaving the sports bar at around 2:30 a.m. She was noted to have been "extremely" intoxicated, and left both her phone and her shoes behind at Kilroy's.

She was next seen entering her apartment complex, and video from security cameras show her so inebriated that she fell out of the open elevator doors.

Rossman reportedly picked her up and carried her out of her building and over to his, and at 3:30 a.m., Rossman's roommate entered their apartment to find him and Lauren there. They were both extremely intoxicated, and Lauren refused to stay there for the night. She wanted to go back to her own apartment.

Lauren was last seen walking south on College Avenue, barefoot, and wearing black leggings and a white tee shirt.

What happened to her from there is a mystery. Her family strongly suspects that the friends she was with that night knew more than they were admitting to; however, the men claim that they have passed polygraph tests with both local police and FBI investigators, and they have never been considered suspects.

Lauren's friends also recounted that she mixed the copious amounts of alcohol she consumed on that morning with both cocaine and Klonopin. She was petite, at under 5 feet tall, and the most prominent theory as to her disappearance is that she suffered a fatal overdose on June 3rd, 2011, and her friends covered it up.

Her family has not stopped their relentless search for their beloved Lauren

Today, they run an official Facebook page which posts updates, information, and various potential clues to a large group of followers. Countless people have dedicated themselves to the search for answers, including internet sleuths on sites like Reddit.com. Her family makes sure to post every detail; for example, this ring is a ring that Lauren wore the morning she vanished. If anyone has seen this ring and/or somehow knows who has, they are encouraged to contact the tip line with their ideas.

The Spierers have encouraged anyone and everyone to print out the poster below and post it anywhere they can. It is entirely possible that someone out there might know a thing or two, but they just haven't come forward yet.
