Kristin Smart Case: New Search Reveals Possible Human Remains

Three decades after Kristin Smart vanished from a California college campus, investigators returned to a familiar location on May 6, 2026, armed with new methodology and determination. Sheriff Ian Parkinson announced that a search warrant was served at the Arroyo Grande home of Susan Flores, mother of Paul Flores, who was convicted of Smart’s murder in 2022. Soil vapor testing-a technique that detects signatures of human remains decomposition-was conducted in the yard and neighboring properties.

“We’ve proven already that Paul did it,” Parkinson said in an interview released Wednesday. “We believe that Kristin, at one time, was on Paul Flores’ father’s property. We know she’s been moved, so where she moved to … we’re hunting that down.”

A Case That Changed Everything

Smart, a 19-year-old Cal Poly student, disappeared over Memorial Day weekend in 1996 after walking back to her dorm from a party with Paul Flores, then also a freshman. Authorities identified Flores as the last person to see her alive, but decades would pass before sufficient evidence emerged to charge him.

The case remained cold for 25 years. When investigators finally arrested Flores in April 2021, they had assembled DNA evidence, phone records, and witness testimony. His trial lasted nearly three months, culminating in an October 2022 guilty verdict for first-degree murder. He was sentenced to 25 years to life.

Despite the conviction, Smart’s body has never been recovered. She was declared dead in 2002, but her family has been unable to lay her to rest.

Institutional Progress Over Decades

The investigation shifted dramatically in 2020 when the sheriff’s office obtained warrants to monitor Flores’s communications. In March 2021, detectives served a warrant at the property of Flores’s father, Ruben, where ground-penetrating radar and hand tools were used to excavate the backyard. Prosecutors alleged Ruben helped hide Smart’s body under the family’s deck before it was relocated.

Ruben Flores was acquitted of charges related to concealing the body, but Paul’s conviction proceeded. The sheriff’s office has continued investigative work even after the trial concluded.

A Family Waits for Closure

Smart’s parents, Stan and Denise, said in interviews years ago that they held one hope: to find their daughter’s remains and finally lay her to rest. “We will have a resolution and he will wish that he’d come forward much sooner,” Denise Smart said in a 1999 interview.

Wednesday’s search represents the latest institutional commitment to that goal. Sheriff Parkinson told podcaster Adam Montiel that the investigation would be “extremely thorough” and could take two or three days. Tim Nelligan, an expert in soil vapor testing, was on site conducting sophisticated analysis of soil composition.

Conviction Stands, Questions Remain

Paul Flores remains imprisoned for Smart’s murder. The conviction established his guilt beyond reasonable doubt, but the absence of her physical remains has prevented the family from achieving complete closure. Investigators continue to follow leads and explore new investigative techniques in hopes of locating Smart’s body and allowing her family to grieve with finality.

The case has drawn nationwide attention, spawning a popular podcast and renewed media coverage. For three decades, Smart’s smiling face appeared on billboards along Highway 101, silent reminders of an unsolved mystery that haunted a small California town.
