LOS ANGELES (AP) — The “prime suspect” in the 25-year-old disappearance of a California college student has been taken into custody and the San Luis Obispo sheriff plans to announce “major developments” in the case. Paul Flores, 44, who was the last person seen with Kristin Smart before she vanished in 1996, was arrested Tuesday in the Los Angeles area. His father, Ruben Flores, was arrested as an accessory at his Arroyo Grande home, where sheriff’s investigators conducted another search. Defense attorney Robert Sanger confirmed that Paul Flores was arrested in the Smart case but he declined to comment on the case.
