Paul Flores, convicted of killing his university classmate Kristin Smart in a case that remained unsolved for decades, has been sentenced to 25 years to life in prison. According to the San Luis Obispo Tribune newspaper, her father, Stan Smart, said: “This is a parent’s worst nightmare — the disappearance and death of their child … we shared her hopes, her dreams, her aspirations as she became a beautiful young adult, and now she will never be able to have a full life. Smart’s mother on Friday described her daughter’s disappearance as “gut-wrenching” and said Flores’s refusal to reveal the location of her daughter’s body was “a cruel and visceral pain that no one should ever have to bear,” the San Luis Obispo Tribune newspaper reported
