Kristin Smart Disappearance and Murder

Kristin Smart was a 19-year-old freshman at California Polytechnic State University (Cal Poly) in San Luis Obispo who disappeared on May 25, 1996, after a party near campus.

The case became one of the longest-running missing person investigations in California history.

Smart, from Stockton, California, attended an off-campus party on the evening of May 24, 1996. Paul Flores was last seen walking alone with her toward the dormitories at approximately 2:00 AM on May 25. Smart never arrived at her dorm room and was never seen again.

When Smart's friends and family could not reach her, Cal Poly campus police began an investigation. Flores was identified early as the last person seen with Smart but provided inconsistent accounts and appeared at class the following Monday with a black eye he could not satisfactorily explain. Despite being the prime suspect from the beginning, Flores was not arrested, and the investigation stalled for years amid criticism of both the campus police and the San Luis Obispo County Sheriff's Office.
