Renewed Search at Susan Flores’ Arroyo Grande Home
On May 6 2026, San Luis Obispo County deputies, assisted by forensic scientists, executed a search warrant at 529 East Branch Street, the residence of Susan Flores, mother of Paul Flores, who was convicted of murdering Kristin Smart in 2022. Investigators employed ground-penetrating radar (GPR) and soil-vapor sampling to locate possible human remains. Soil analysis returned “positive results consistent with human decomposition,” but no body or identifiable remains were recovered before the search concluded on May 9.
Background: 1996 Disappearance and 2022 Conviction
Kristin Smart, a 19-year-old California Polytechnic State University freshman, vanished on May 25 1996 after an off-campus party. Paul Flores, the last person seen walking with her, was arrested in 2021, convicted of first-degree murder in 2022, and sentenced to 25 years-to-life. His father, Ruben Flores, was tried as an accessory in 2022 and acquitted. Smart was declared legally dead in 2002; her remains have never been found.
Key Figures and Groups
- Kristin Smart – missing student.
- Paul Flores – convicted murderer, currently incarcerated.
- Susan Flores – mother of Paul Flores, person of interest, not charged.
- Ian Parkinson – Sheriff of San Luis Obispo County, leads the investigation.
- Dan Dow – District Attorney, oversees prosecutorial support.
- Tim Nelligan, Steve Hoyt, Brian Eckenrode – forensic scientists specializing in soil-vapor analysis and human decomposition.
Forensic Techniques and Findings
Scientists collected soil samples from the front and back yards and a neighboring parcel. Volatile organic compounds associated with cadaver decomposition were detected, a result described as “positive” by the sheriff. GPR identified subsurface anomalies, though investigators noted some could be utility lines. The technology used represents an advancement over earlier 1996 and 2020 searches, allowing deeper and more precise scanning.
Official Statements & Responses
Sheriff Parkinson emphasized that the search will continue until all leads are exhausted, noting the property will remain sealed while evidence is evaluated. District Attorney Dow reiterated the office’s commitment to “using every lawful tool available” to locate Smart’s remains and to support the Smart family. The sheriff’s office released a statement confirming that no remains were recovered and that detectives will analyze any collected evidence.
Criticism & Opposition
The Flores family has not cooperated with investigators, and Susan Flores remains a person of interest without charges. Paul Flores maintains his innocence and has appealed his conviction. No external agencies have challenged the forensic findings, but the inability to identify the remains leaves the case unresolved.
On-the-Ground Reports
Reporters observed GPR units, soil-vapor probes, and shovels being deployed in the backyard and interior of the house. Tarps were installed to conceal ongoing work. Investigators also examined a neighboring yard, and a “kick-out” warrant prevented occupants from returning during the operation.
Conflicting Reports & Gaps
All sources agree that human-decomposition evidence was found, yet none can confirm the remains belong to Smart. No arrests or new charges have been announced, and the sheriff declined to disclose the specific trigger for the warrant.
