John Segale, a spokesman for the Smart family, told CNN that the family had been informed by law enforcement officials on Tuesday that Paul Flores and his father, Ruben Flores, had been arrested Tuesday morning.
Two law enforcement sources have confirmed the arrests were made on Tuesday. Paul and Ruben Flores are in custody of the San Luis Obispo County Sheriff’s Office, one source said.
Last month, authorities searched Ruben Flores’ home in Arroyo Grande. Flores’s son, Paul, has remained the prime suspect in the decades-long missing persons case.
News of the arrest was met with emotion by the Smart family, Segale said.
There were “a lot of really emotional moments,” he said. “Many prayers, surprise, excitement, happiness and of course sadness. Sadness, because this has been going on for 25 years. The Smart family could not have buried their daughter. There was no closure.”
The San Luis Obispo County Sheriff’s Office is scheduling a press conference at 2:00 p.m. local time (5:00 p.m. ET).
Smart was pronounced dead in 2002.
Last year, investigators searched Paul Flores’ home and said they had found ‘interesting objects’ on the property.
At the time, Flores was detained at his home in San Pedro, California, and released after the search, Tony Cipolla, a spokesman for the sheriff’s office, said at the time.
Smart disappeared after she and other students walked home from a fraternity party.
She was last seen near her dorm, police said, but never entered her room. Friends and family never heard from her again, authorities said.
She had no ID, money or extra clothing when she disappeared, police said.
A massive search and repeated interviews with a college student who walked her that evening didn’t produce any breaks, and Smart was pronounced dead in 2002.
Last year, the sheriff’s office said it was working on the case and listed its efforts since 2011, when the current government took over, including: conducting 18 searches in nine locations; submitting 37 pieces of evidence for DNA testing; the retrieval of “140 new supporting documents”; and conducting 91 interviews.
