SAN QUENTIN, Calif. (KCBS/AP)  -- Authorities are looking for a missing flash memory drive with the personal information of thousands of people who've visited San Quentin.

Prison officials tell the San Francisco Chronicle that the drive contains names, birth dates and driver's license numbers of more than 3,500 people.

San Quentin officials have not received reports of ID theft connected to the incident, which was first reported at the beginning of the month.
