San Diego County Deputy District Attorney Marnie McGee said Maria Nater, 45, pleaded guilty Tuesday and will likely receive a probation sentence at an April 25 hearing, KSWB-TV, San Diego, reported Thursday.
Authorities said an investigation was opened when workers at a Carlsbad library noticed significant book loss and a search of Nater's Vista home turned up thousands of missing library books and DVDs, worth an estimated $5,400, with some packaged to be shipped.
Nater, who was arrested in September, admitted to taking the books from libraries in Carlsbad, Oceanside and San Diego. She said she was selling the pilfered items on Amazon.com.
