She was last seen on June 3 after a night of partying with friends at a bar.

Special Section: Lauren Spierer

A ceremony in her honor is scheduled to be held at noon on Friday at the Hillel Center on IU’s campus.

Spierer’s parents said they will not attend the ceremony because it’s a painful reminder that she is still missing.

"It's still sad. I still hope that they find her and there's some kind of closure," student Kelly O'Connor said.

Bloomington police released a statement detailing the efforts that detectives have put forth to find Lauren, and that the investigation is still active.

Indiana Excise Police said they have cracked down on underage drinking on college campuses in the past year since Lauren disappeared, RTV6’s Tanya Spencer reported.

Students said undercover officers have been working closely with bars.

"When people try to get in underage or with other people's IDs or whatever, they just write them tickets on the spot," student Chas Nulph said.

Police said they have people of interest in the case, but no arrests have been made.

Detectives asked anyone with information about Lauren Spierer’s disappearance to contact Bloomington police at 812-339-4477.

A $250,000 reward is being offered.
