The execution of a search warrant at the home of the mother of Kristin Smart’s convicted killer has entered day two.
Shortly before 9 a.m. Thursday, law enforcement could be seen coming and going from the backyard of Susan Flores' home on East Branch Street in Arroyo Grande. People involved in soil testing also arrived at the scene.
The sheriff’s office first served Flores with the search warrant early Wednesday morning.

Sheriff’s officials tell KSBY that Flores is not allowed on the property while the warrant is being executed. It’s unknown when it will wrap up.
While the sheriff’s office has not elaborated on what prompted the latest search or whether anything of significance has been found, digging sounds could be heard coming from the backyard on Wednesday and various people on site, including former cold-case investigator for the sheriff's office, Clint Cole, and San Luis Obispo County Sheriff Ian Parkinson.

Flores’ son, Paul, was convicted in 2022 of murdering Kristin Smart 30 years ago this month.
Investigators have said Flores was the last person to be seen with the 19-year-old Cal Poly freshman on May 25, 1996.
While Smart was later declared legally dead and Flores is now serving a 25 years-to-life sentence for the murder, her remains have never been found.
KSBY News reached out to the sheriff's office and was told that Sheriff Ian Parkinson is not doing interviews regarding the investigation; however, Parkinson did speak with local Up+Adam podcast host Adam Montiel for his Thursday morning show.
Sheriff Parkinson said this week's search is not the first since Flores' conviction. He told Montiel that nothing had changed to make them go back to Susan Flores' property, and that they've been continuing to work on the case since Paul Flores' conviction in 2023.
"Our goal is to take this wherever leads, wherever probable cause, wherever a judge signs off on our probable cause, to go until we find Kristin," Parkinson said.
He declined to provide additional details on prior searches, but said another very substantial one has been conducted since the fall of 2023.
He said that those involved in the case remain committed to bringing Kristin home and bringing anyone responsible for her death to justice.
