The warrant was for “specific items of evidence,” the sheriff’s department said. However, the exact purpose was sealed by a court.

In May of 1996, Kristin Smart of Stockton disappeared while a freshman at California Polytechnic State University. She was last seen leaving an off-campus party. Her body has never been found.

Flores was a fellow student at Cal Poly at the time of Smart’s disappearance and is believed to be the last person to see her alive.

Back on Feb. 5, the FBI and the San Luis Obispo County Sheriff’s Office (SLOCSO) searched Flores’ home. He was detained in an LASD squad SUV, handcuffed, questioned, and then released by deputies after signing some paperwork.

It was one of four search warrants served that day by San Luis Obispo County Sheriff’s deputies. Two others were in San Luis Obispo County and the fourth was in Washington state.
