SHERMAN, Texas -- A former elementary school principal was sentenced to 10 years in federal prison on Monday for child exploitation.

Oscar Figueroa, the former principal at Viridian Elementary in Hurst-Euless-Bedford ISD, was arrested in July of 2015 after an undercover agent posing as a 16-year-old boy answered an ad Figueroa posted on Craigslist, asking men to meet him for sex at the AMC movie theater in Stonebriar Centre in Frisco.

Figueroa was convicted in April 2016 after a four-day trial. During the trial, prosecutors introduced Figueroa’s text messages with the undercover agent as well as approximately 120 Craigslist ads Figueroa posted seeking sexual activity.

U.S. District Judge Amos L Mazzant sentenced Figueroa to 120 months in federal prison as well as ordering him to pay fines and assessments totaling $17,600. Upon his release, Figueroa will be required to register as a sex offender and will have 10 years of supervised release.
