SAN PEDRO, Calif. (KTLA) -- Investigators returned to San Pedro on Wednesday to serve another search warrant at the the home of Paul Flores, the man identified as a person of interest in the 1996 disappearance and unsolved death of Cal Poly San Luis Obispo student Kristin Smart.

It’s the second time this year that authorities have searched Flores’ home in connection with the high-profile missing persons case.

On Feb. 5, the residence was was one of four locations in California and Washington where warrants were served, according to the San Luis Obispo County Sheriff’s Office.

The latest search warrant is “for specific items of evidence” at the house, a sheriff's news release stated. Authorities said they could not provide any additional information about the search warrant because, like the ones served in February, it is sealed by the court.

Sources told the Los Angeles Times back in the February that investigators were trying to gather DNA and other physical evidence that could provide clues about what happened to Smart, whose body was never found.

The 19-year-old was declared legally dead in 2002.

Flores has long been associated with the case. A former classmate at Cal Poly SLO, he was the last person to see Smart before she vanished after attending an off-campus party nearly 24 years ago.
