Twenty-six years after 19-year-old Cal Poly freshman Kristen Smart vanished on a Memorial Day weekend in 1996, her case finally reached a verdict—after a relentless pursuit by her parents, a decade of investigative dead ends, and a breakthrough from a podcast that reignited national attention. The investigation began with a troubling pattern: a young woman seen passed out at a party, last seen walking home with Paul Flores, a 19-year-old freshman with a history of social isolation and troubling behavior. Despite initial inaction by campus police, cadaver dogs alerted to human remains scent in Flores’ dorm room—evidence that would haunt him for years. Over time, inconsistencies in his story, a black eye with no credible explanation, and a disturbing admission from a teenage witness who claims he confessed to killing her in a rural backyard, built a circumstantial case. A 2021 search under his father’s deck using ground-penetrating radar and forensic soil analysis uncovered human blood and fibers matching Kristen’s clothing—enough to secure an arrest. Though no body was found, prosecutors built a powerful case around behavioral patterns, victim testimony from women who were drugged and raped by Flores, and the dogs’ alerts. In 2021, Paul Flores was convicted of murder, while his father Ruben was acquitted. The trial, one of the rare dual-jury cases in a no-body murder, was a landmark in California criminal justice.
Cadaver dogs alerted to human decomposition scent in Paul Flores' dorm room over a month after Kristen Smart vanished—evidence that was ignored at the time but became pivotal years later.
The Smart family’s relentless advocacy, including civil lawsuits and public pressure, forced law enforcement to re-examine the case after 25 years of stagnation.
Paul Flores was convicted in a no-body case based on circumstantial evidence, including victim testimony from women who were drugged and raped, and forensic soil analysis revealing human blood under his father’s deck.
Despite the conviction, Kristen Smart’s remains have never been found, meaning the family still lacks closure and the case remains emotionally unresolved.
The 2021 conviction was the result of a 26-year investigation, highlighting systemic failures by Cal Poly police who delayed reporting and failed to conduct proper forensic searches.
…and 3 more takeaways available in PodZeus
The Disappearance of Kristen Smart
On Memorial Day weekend 1996, 19-year-old Cal Poly freshman Kristen Smart vanished after attending a small off-campus party. She was last seen walking home with Paul Flores, a fellow student. Her red backpack remained untouched in her dorm, and she had no ID, keys, or wallet—unlike her usual habits. The campus police initially dismissed her disappearance as a common student disappearance, delaying a formal report for over two days.
The First Red Flags
Paul Flores, the last person seen with Kristen, gave conflicting stories about a black eye he claimed came from basketball. Investigators later found no evidence of such a game. Cadaver dogs alerted to human remains scent in his dorm room during a search months later—evidence that should have been pursued earlier. The campus police failed to conduct proper forensic searches, including fingerprinting or fiber analysis.
The Family’s Fight for Justice
Kristen’s parents, Denise and Stan Smart, became relentless advocates, contacting media, sending flyers to every Taco Bell in California, and even confronting Paul at a gas station. They filed a civil lawsuit, forcing Paul to answer questions under oath—even though he invoked the Fifth Amendment 27 times. Their persistence kept the case alive despite official inaction.
The Rise of a Serial Killer Theory
Two more local college students disappeared in the following years, fueling fear that a serial killer was at large. A suspect, Rex Allen Krebs, was convicted of two of the murders—but ruled out in Kristen’s case due to an alibi. The investigation refocused on Paul Flores, who had a history of predatory behavior, including being called 'Chester the Molester' by peers.
The Breakthrough: A Podcast and a Confession
“Out of the blue. A guy you don't know... comments on a PSA about a missing young woman and says, basically I killed her and buried her in my yard.”
“I said are you sitting down? I said why? He said Sheriff this is human blood. My heart just stopped and all I could think of was we finally caught our break.”
“We're not happy because we don't have our daughter. We don't know where her remains are. So from that aspect, you know, we don't have closure.”
“Dogs don't lie. We watched that video two days. I mean, his body language in itself, he's pulling on a shirt and looking down and not really making eye contact.”
