Cal Poly student Kristin Smart went missing Memorial Day weekend in 1996. Now, 26 years later, the last person to see her alive has been found guilty of her murder.
Paul Flores, 45, was convicted of first-degree murder on Tuesday and is expected to be sentenced for the crime in December. He is facing a potential life sentence.
His father, 81-year-old Ruben Flores, was found not guilty of charges of accessory to murder after the fact; Ruben Flores had been accused of helping his son hide Smart’s body.
Now that the decades-long case has reached a guilty verdict, The Tribune has compiled a look back at it the important moments over the 26 years since Smart was last seen.
