Ever See That Movie 'Thirteen'?

Jeffrey Anderson, 23, of Tohickon Middle School in Bucks County, was arrested last week and charged with crimes including involuntary deviate sexual intercourse, aggravated indecent assault, and criminal use of communications devices. According to court records, Anderson admitted that he kissed, fondled and digitally penetrated the girls, age 15 and 14, inside the 15-year-old's house on a recent Saturday afternoon. He also engaged in oral sex with the younger girl during the April 30 meeting, the records say.

The girls' parents recently confronted their daughters after learning their daughters had been communicating with Anderson by computer instant messaging and through Facebook.com personal Web sites, a probable cause affidavit said.

Both girls had been in Anderson's class, and had been messaging him outside of school for about a month. In some exchanges, Anderson told the girls he wanted to have sex with them, the affidavit says, and recently met with them in a Tohickon classroom and kissed them.

In an April 22 Facebook posting, Anderson pleaded with the girls to keep things quiet, "PLEASE . . . nothing that is said or done between the three of us can EVER be repeated to anyone else!!!" the message said. "Not your best friend, your diary, or any of those girls at school!! I could get fired, never become a teacher again. or go to jail. . ." Five days later, Anderson allegedly added: "Hah . . . im so going to hell . . . I can't believe I hooked up with two 9th graders!!"

On Saturday, April 29, the affidavit says, Anderson was text-messaging the girls on his cell phone when he learned that the 15-year-old's parents would be away for the day. At about 4 p.m. he parked his vehicle down the block from the girl's house and met both girls inside, where they engaged in sexual acts.
