Lauren Spierer was a 20-year-old Indiana University student when she vanished in the early hours of June 3, 2011, after a night out in Bloomington. She was last seen walking alone near 11th Street and College Avenue at about 4:30 a.m., leaving the apartment of an acquaintance. Despite searches by local police, the FBI, and thousands of volunteers, Lauren has not been found and her disappearance remains unsolved.

Surveillance footage, interviews with friends, and thousands of public tips have been examined without producing a definitive lead. Investigators searched surrounding lakes and wooded areas and explored several theories, including accidental overdose, involvement of people she was with that night, and the possibility of a stranger abduction; Lauren’s parents do not believe it was random. The men she spent time with that night have been criticized for limited cooperation, though they say they have shared what they know.

The Bloomington Police Department describes the investigation as active, and a 2024 book renewed public attention and raised potential new evidence and interviews. If anyone knew Lauren that night or has information that hasn’t been shared with investigators, please come forward.
