A former New Berlin Eisenhower student was accused Wednesday of a pattern of manipulation and deception using the social networking site Facebook to coerce male schoolmates into sexual encounters. Anthony R. Stancl, 18, posing as a female on Facebook, persuaded at least 31 boys to send him naked pictures of themselves and then blackmailed some of the boys into performing sex acts under the threat that the pictures would be released to the rest of the high school, according to a criminal complaint. The sexual assaults occurred in a bathroom at the high school, the school parking lot, a New Berlin Public Library restroom, Valley View Park, Malone Park, Minooka Park and at some of the victims' home. At least seven boys, 15 to 17, were forced into performing sex acts, Schimel said. The incidents occurred from spring 2008 until the time of Stancl's arrest in November.
