WAUKESHA, Wis (WSAU) A teenager who used Facebook to blackmail his classmates for sex was sentenced to 15-years in prison yesterday. He could have faced 30-years.

Anthony Stancl of Waukesha, who's now 19, posed as a teenage girl on Facebook and tricked more than 30 of his classmates to send him nude photos. He used those photos as blackmail to have sex with his victims. At least seven of the teens gave in.

Stancl pled guilty in February to two felonies, including sexual assault of a minor.

He said in court that he's come to understand what his victims went through. He showed no emotion as his sentence was handed down yesterday.
