SALINAS — The last man seen with Kristin Smart was convicted Tuesday of killing the Cal Poly San Luis Obispo freshman, who vanished from campus 26 years ago.

Jurors unanimously found Paul Flores guilty of first-degree murder, the San Luis Obispo Tribune reported.

His father, Ruben Flores, was found not guilty of accessory after the fact. He had been accused of helping hide Smart’s body.

Smart disappeared over Memorial Day weekend in 1996. Her remains were never found.

Prosecutors maintain the younger Flores, now 45, killed the 19-year-old during an attempted rape on May 25, 1996, in his dorm room at Cal Poly, where both were first-year students. He was the last person seen with Smart as he walked her home from an off-campus party where she became intoxicated.

Jury Didn’t Believe Defense Arguments

The son’s defense attorney, Robert Sanger, had tried to pin the killing on someone else — noting that Scott Peterson, who was later convicted at a sensational trial of killing his pregnant wife and the fetus she was carrying — was also a Cal Poly student at the time.

During his closing arguments, Sanger told jurors that no attempted rape occurred and he cast doubt on testimony from witnesses, including a student who was in Smart’s dorm who testified to seeing Flores in Smart’s room.

He also referred to forensic evidence offered by the prosecution as “junk science.”

“This case was not prosecuted for all these years because there’s no evidence,” Sanger said. “It’s sad Kristin Smart disappeared, and she may have gone out on her own, but who knows?”

Arrests Finally Made Last Year

Paul Flores had long been considered a suspect in the killing. He had a black eye when investigators interviewed him. He told them he got it playing basketball with friends, who denied his account, according to court records. He later changed his story to say he bumped his head while working on his car.

However, the father and son were only arrested in 2021 after the case was revived.

Investigators conducted dozens of fruitless searches for Smart’s body over two decades but in the past two years they turned their attention to Ruben Flores’ home about 12 miles south of Cal Poly in the community of Arroyo Grande.

Behind latticework beneath the deck of his large house on a dead-end street, archaeologists working for police in March 2021 found a soil disturbance about the size of a casket and the presence of human blood, prosecutors said. The blood was too degraded to extract a DNA sample.

The trial was held in Salinas, 110 miles north of San Luis Obispo, after a judge granted a defense request to move it. The defense argued that it was unlikely the Flores could receive a fair trial with so much much notoriety in the city of about 47,000 people.

For a quarter century, the quest to find out what happened to Smart frustrated Central Coast residents while captivating independent sleuths and crime bloggers. Most nearly every TV true crime show has reported on the case.
