Monday marks 24 years since the disappearance of Kristin Smart.
The 19-year-old was last seen on May 25, 1996 outside her dorm after leaving an off-campus party.
She was weeks away from finishing her freshman year.
Paul Flores, who witnesses say was one of the last people to be seen with Smart, has never been named a suspect but remains a person of interest in the case.
The San Luis Obispo County Sheriff's office has served multiple search warrants at his San Pedro home this year as well as at his parents’ homes in Arroyo Grande.
With search warrants sealed, the specifics of what investigators were looking for has not been released.
When KSBY spoke with San Luis Obispo County Sheriff Ian Parkinson about the case last month, he said he talks with Smart's parents, Stan and Denise, about every two to three weeks and says bringing closure to the family is still a priority.
“Time is something that is concerning because most of us would have wanted this thing brought to an end a long time ago, but we have to focus on thorough work right now and focusing on what we can prove and not what people may believe," Parkinson said shortly after the latest search warrant was served at Flores’ home.
A cruise honoring Smart is planned at 6 p.m. Monday.
Drivers will meet behind Rooster Creek Tavern in the the Village of Arroyo Grande and drive to Smart's memorial in Shell Beach.
We reached out to the Smart family spokesperson and he said the family has no comment.
