Middle School Teacher Admits "I Can't Believe I Hooked Up With Two 9th Graders!" - Jeffrey Anderson, Tohickon Middle School

Frankly, neither can we Jeff, but that's what the police say happened. Jeffrey Anderson, 23, had been the building substitute at Tohickon Middle School in Plumstead Township outside Philly . . . until the parents of a 15-year-old girl used computer monitoring software to capture an exchange between the teacher and one girl that included the message (allegedly from Anderson) that read: "Hah . . . im so going to hell . . . I can't believe I hooked up with two 9th graders!!"

Here's more from the Philadelphia Enquirer:

Jeffrey Anderson, 23, of Northeast Philadelphia, was arrested Monday night and charged with crimes including involuntary deviate sexual intercourse, aggravated indecent assault, and criminal use of communications devices.
Anderson had been the building substitute at Tohickon Middle School in Plumstead Township. Detectives pulled him out of his classroom Monday for questioning, and he provided a 14-page confession, court records say.
Anderson was fired immediately by the Central Bucks School District, where the La Salle University graduate had worked since 2005.
According to court records, Anderson admitted he kissed, fondled and digitally penetrated the girls, ages 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 28 meeting, the records say.
If convicted of the most serious crimes, Anderson faces a mandatory minimum five years in state prison. He is being held in Bucks County prison in lieu of $500,000 bail.
The girls' parents had been alerted by computer monitoring software that their daughters had been communicating with the teacher via instant messaging and Facebook.com personal Web sites, District Attorney Diane Gibbons said. They confronted the girls, who admitted engaging in sexual acts with Anderson, 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, the affidavit says.
"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, after an explicit proposition to the girls on Facebook, Anderson allegedly added: "Hah . . . im so going to hell . . . I can't believe I hooked up with two 9th graders!!"
