Kristin Smart Case: Paul Flores and the Missing Body

Around 2 a.m. on Saturday, May 25, 1996, students leaving a birthday party on Crandall Way in San Luis Obispo found a Cal Poly freshman passed out on a neighbor’s lawn. Kristin Smart was 19, wearing red Puma sneakers, black shorts and a light grey top. Two of them, Cheryl Anderson and Tim Davis, got her on her feet and started toward Muir Hall. A third, a 19-year-old freshman named Paul Flores, said he would take her the rest of the way. At the edge of campus, the others turned off. Flores later told police he left Kristin outside his own dorm, Santa Lucia Hall, and watched her walk on alone. No one who knew her ever saw her again.

A Freshman From Stockton and a Slow Alarm

Kristin grew up in Stockton, California, the daughter of two teachers, Stan and Denise Smart. When she failed to call home over Memorial Day weekend, her parents phoned the campus. University police treated her as an adult who might have left with friends, and days passed before a missing-person case was opened.

When investigators sat down with Flores, he had a black eye. He said it came from basketball, then changed the story to a car accident. He was a person of interest almost immediately, but there was no body and no crime scene. In 1998 the Legislature passed the Kristin Smart Campus Security Act, requiring public colleges to coordinate with local police on violent crimes and missing students; it took effect January 1, 1999. On May 25, 2002, six years to the day after she vanished, a court declared Kristin legally dead.

Two Decades of Digs and Dead Ends

The Smarts filed a wrongful-death suit against Flores in 2005, but it collapsed when he invoked the Fifth Amendment. The family kept pressing anyway. In 2016 the FBI brought cadaver dogs to a hillside on the Cal Poly campus and excavated three sites, recovering what the agency would only describe as “items of interest.” None of it produced a charge.

The disappearance of Maura Murray and the Asha Degree disappearance both sat for years with a plausible theory and nothing a prosecutor could take into court. What the Smart case needed was people who had stayed quiet since 1996 to start talking.

A Musician From Orcutt Picks Up a Microphone

Chris Lambert was a songwriter from Orcutt, a small town south of San Luis Obispo, with no background in journalism. On September 30, 2019, he released the first episode of a podcast he called “Your Own Backyard.” Meticulous and relentless, it was downloaded more than 5 million times in six months.

The San Luis Obispo County Sheriff’s Office later said the podcast encouraged witnesses who had never spoken to detectives to come forward. In February 2020, deputies served a new round of search warrants. In April 2020 they searched Paul Flores’s home in San Pedro and seized material that prosecutors would later use to argue he had a pattern of drugging and assaulting women.

Under the Deck at 710 White Court

On March 15 and 16, 2021, investigators returned to the Arroyo Grande home of Paul’s father, Ruben Flores, at 710 White Court. Under the back deck, archaeologists mapped a soil disturbance roughly 4 feet by 6 feet and about 4 feet deep. Four samples from the deeper soil tested positive for human blood, too degraded to yield a DNA profile. The dirt also held red, blue, brown and black fibers, colors matching the clothes Kristin wore the night she vanished.

A neighbor told detectives that in February 2020, shortly after an earlier search, she had watched Ruben Flores, his ex-wife Susan and Susan’s boyfriend trying to back an enclosed trailer up to the house near the deck. Prosecutors came to believe the grave had recently been emptied. On April 13, 2021, deputies arrested Paul Flores, 44, for murder and Ruben Flores, 80, as an accessory after the fact.

Two Juries in Salinas

Because of publicity at home, the trial was moved 110 miles north to Monterey County Superior Court in Salinas. Opening statements began July 18, 2022, before Judge Jennifer O’Keefe, with separate juries for father and son. Deputy District Attorney Christopher Peuvrelle argued that Paul Flores killed Kristin during an attempted rape in his dorm room and that his father helped bury her and later moved her. The defense called the soil evidence ambiguous.

On October 18, 2022, after a three-month trial, Paul Flores’s jury found him guilty of first-degree murder. Ruben Flores’s jury acquitted him. On March 10, 2023, Judge O’Keefe sentenced Paul Flores to 25 years to life and ordered him to register as a sex offender, calling him “a cancer to society.” As with the Austin yogurt shop murders, the verdict came decades late and left questions behind.

Prison Attacks and Failed Appeals

Flores went to Pleasant Valley State Prison in Coalinga. In August 2023 another inmate, Jason Budrow, slashed his neck; Flores spent two days in a hospital. On April 10, 2024, he was stabbed in the recreation yard, and on June 6, 2024, the state moved him to Corcoran State Prison for his safety.

His lawyers argued that cumulative errors at trial required reversal, or at least a reduction to second-degree murder. On October 24, 2025, the Second District Court of Appeal affirmed the conviction, and in January 2026 the California Supreme Court declined to review it. District Attorney Dan Dow said the decision brought “a stronger sense of finality.”

Thirty Years Later: A Side Yard and a Grove

In early May 2026, weeks before the 30th anniversary, the sheriff’s office served a warrant at the East Branch Street home of Susan Flores, Paul’s mother, in Arroyo Grande. Ground-penetrating radar and soil-vapor testing pointed to a side yard, where Sheriff Ian Parkinson said compounds matched human decomposition. “We believe that human remains were there at one time or still there,” he said. Crews pulled up pavers and sifted the soil. When the search ended on Saturday, May 9, the department said it had recovered “several items considered evidentiary in nature,” but not Kristin.

On July 28, 2026, Cal Poly announced Kristin’s Grove, a memorial and gathering space near Dexter Lawn designed with architecture students at the family’s request. It is scheduled to open with the fall term and be dedicated later in the year.

Why This Case Still Matters

Kristin Smart’s case rewrote how California campuses respond when a student goes missing, and it proved a murder can be prosecuted without a body if the circumstantial record is deep enough. It also showed what an outsider with patience can do: Chris Lambert kept knocking on doors investigators had walked past for years, and the sheriff, the district attorney and the university all thanked him publicly after the verdict. The lesson the Smarts spent three decades teaching is simple: the first days matter, and so does the 10,000th.

Between a hillside in San Luis Obispo, a deck on White Court and a side yard on East Branch Street, the ground has kept hinting at the same answer for 30 years, and the items pulled from that yard in May are still in a lab.
