A Long Beach bookstore owner was sentenced to state prison Tuesday after pleading no contest to charges he orchestrated a scheme to steal thousands of textbooks with the help of employees from four school districts.

Corey Frederick, 44, pleaded no contest to four felony counts of embezzlement and one felony count of bribing a public officer, according to the Los Angeles County District Attorney’s Office.

Frederick, who owned Doorkeeper Textz, was sentenced to 5 years and 8 months in a state prison and must also pay $793,306 in restitution to the Los Angeles Unified School District, according to county officials.

Investigators said Frederick paid more than $200,000 in bribes to a dozen employees of LAUSD and school districts in Inglewood, Lynwood and Bellflower over the course of two years. Some employees received as much as $47,000 for the stolen textbooks.

Frederick and a dozen other people were charged in August 2013, and all but one person has now been convicted, according to the D.A.’s Office.
