Flores’ father, Ruben, also was arrested at his home in the city of Arroyo Grande, according to news outlets.
The San Luis Obispo County Sheriff’s Office did not immediately respond to Fox News’ コメントのリクエスト.
The sheriff’s office earlier on Tuesday said it will announce “major developments” in the investigation at 2 午後. 現地時間.
Flores, who was a student with Smart at California Polytechnic State University, San Luis Obispo, was believed to be the last person seen with her before the 19-year-old vanished while walking back to her dorm after a party.
In the nearly 25 years since Smart’s disappearance, Flores has denied any wrongdoing. He invoked his Fifth Amendment right to not answer questions before a grand jury and in a deposition for a lawsuit that Smart’s family brought against him in civil court.
San Luis Obispo County Sheriff Ian Parkinson named Flores as the “prime suspect” in the case last month and investigators searched his father’s home and property in Arroyo Grande, 約 15 miles south of the university, using ground-penetrating radar and cadaver dogs.
Search warrants were served last year on Flores’ home in the San Pedro area of Los Angeles and at other locations in California and Washington state. Investigators conducted digs on the campus in 2016.
