It has been 10 years since 19-year-old Kristin Smart disappeared. Smart, the daughter of then Vintage High School principal Stan Smart and now Napa Valley Unified School director of student services, was a freshman at Cal Poly University in San Luis Obispo when she vanished.

She was last seen walking to her dormitory room, accompanied by a 19-year-old male student on the Friday night of the Memorial Day weekend in 1996. The pair had been to a party. Since that night, there has been no trace of Smart or explanation for her disappearance.

To commemorate the 10-year anniversary of their daughter's disappearance, the Smarts, along with numerous supporters, have organized the Kristin Smart Hope & Awareness Fun Run May 20 in Arroyo Grande, just south of San Luis Obispo.

"The most important thing is that Kristin will not be forgotten. We need to keep our daughter's memory alive," said Kristin's mother, Denise Smart.

The proceeds benefit Kristin Smart Point of Hope Overlook at Dinosaur Caves in Shell Beach.

"Kristin loved the ocean and anything to do with the sea. This place at Shell Beach is so beautiful and peaceful. She would have just loved it," Denise Smart said.
