Despite advanced soil testing and new warrants, the search for Kristin Smart’s remains at Paul Flores’ mother’s Arroyo Grande home has ended without recovery, leaving the case wide open.
In the 30-year investigation into the 1996 disappearance of Kristin Smart, a fresh chapter has closed without resolution. Authorities recently concluded a intensive search at the Arroyo Grande home of Susan Flores, mother of Paul Flores, who was convicted of Smart’s murder in 2022. Despite new soil testing returning signs of human remains, investigators did not recover Smart’s body during this operation, leaving the case’s most critical question unanswered.
The latest search underscored a renewed commitment to finding answers after advances in forensic technology prompted a renewed look at the property. San Luis Obispo County Sheriff Ian Parkinson told reporters that while the search concluded, the case remains "wide-open" until Smart is found. Investigators used ground-penetrating radar and new soil science methods to scour the packed garage and deck areas, driven by a search warrant based on undisclosed "investigative leads" and information from a witness.
The decision to search the Flores family home again was driven by significant technological advancements. Parkinson explained that new soil testing had returned indications of human remains, specifically analyzing compounds related to a decomposing body. Tim Nelligan, an expert in soil vapor testing, confirmed he was on the premises gathering samples from the yard. Nelligan noted that his team had developed a methodology to assess soil vapor and its relation to human cadaver decomposition.
"We’re also conducting soil tests and that’s kind of the scientific part... it’s about the compounds in the soil that are related to a human decomposing body," Parkinson said. The process was described as methodical, with teams analyzing data nightly to match thresholds against known decomposition markers. However, the physical environment complicated efforts. The sheriff described the yard as a "very small area" that was "quite crowded with stuff," making the search difficult.
Although evidence indicated human remains "were there at one time or still there," authorities could not confirm if they belonged to Smart. The sheriff’s office stated that any recovered evidence would be sent for evaluation, but no remains were found in this specific operation. The warrant permitting the search remains sealed, meaning the underlying evidence presented to the judge is not public.
For the Smart family, the lack of recovery continues to cause profound pain. Stan and Denise Smart have long expressed hope that they can one day lay their daughter to rest. "Until we have Kristin, everything is still wide-open," Parkinson noted, reflecting the family’s sentiment that justice is incomplete without her physical return. The family has described their experience as a daily weaving of "heartache, frustration, and setbacks" over three decades.
In a statement, the Smart family emphasized their desire for resolution. Denise Smart previously told Paul Flores, "We will have a resolution and he will wish that he’d come forward much sooner." Her husband added, "We believe he’s definitely involved... The best outcome would be that we’d be able to find our daughter’s remains and we’d be able to have some justice."
The investigation has long centered on Paul Flores, who was last seen with Smart on the California Polytechnic State University campus during Memorial Day weekend in 1996. Flores was convicted of first-degree murder in October 2022 and sentenced to 25 years to life. His father, Ruben Flores, was acquitted of charges that he helped hide the body. However, suspicions regarding the family home have persisted.
Prosecutors previously alleged that Paul Flores killed Smart in his dorm room and enlisted his father to hide her body under the family deck before relocating the remains. The sheriff noted that Susan Flores has long been a person of interest, though she has never faced charges. Parkinson stated, "We have no lawful reason to detain her at this point."
The search at the home follows previous investigations, including a 2021 search of Ruben Flores’ property where additional evidence was discovered. Despite these efforts, the location of the remains remains unknown. Parkinson suggested that Smart’s body may have been moved multiple times, noting, "Just because somebody’s house was searched doesn’t mean that we’re not going back there, because she could have been moved back there thinking that it’s a safe place."
The conclusion of the search at Susan Flores’ home marks another temporary halt in the pursuit of Paul Flores’ conviction’s physical evidence. While no remains were found, the use of advanced soil vapor testing provides a new forensic path for future inquiries. The Sheriff’s Office remains fully committed to finding Smart, but the lack of recovered evidence keeps the case’s final chapter unwritten. Future investigations will likely rely on the re-evaluation of the sealed warrant’s evidence, as the family continues to wait for the justice of seeing their daughter laid to rest. The persistent hope for a resolution remains, even as the physical evidence eludes investigators.
