A New Berlin teen who pleaded no contest blackmailing his classmates for sex through Facebook was sentenced Wednesday to 15 years in prison. 19-year-old Anthony Stancl apologized during sentencing, saying he has learned to understand what his victims went through.

Stancl was accused of posing as a girl on Facebook and tricking more than 30 male classmates into sending him naked photos of themselves, then using the photos to blackmail them for sex.

He pleaded no contest in December to two felonies, including repeated sexual assault of a child.

Prosecutors are satisfied with the sentence of 15 years in prison along with another 13 years of extended supervision. Stancl had faced a maximum 30-year sentence.
