Teacher, 32, 'had sex with pupil, 13, and sent him sexually explicit pictures'

Arrest: Married school teacher Mary Faith McCormick, pictured left in her mug shot and right, stands accused of having sex with a 13-year-old student. She also allegedly sent him explicit text messages and photos

Mother-of-one Mary Faith McCormick, 32, is accused of having a three-month affair with the teenager after he contacted her on social media.

According to a probable cause affidavit the two had consensual sex at least twice. The sexual encounters began after a friend 'dared' the 13-year-old to contact McCormick. The report said the teen and a friend went over to the teacher's apartment to watch a movie.

When the friend left, the boy remained behind and later had sex with the teacher in her bedroom, the affidavit states.

She is also accused of sending explicit text messages to the boy, according to 5newsonline.

According to legal papers on the case they are believed to have had sex on at least two occasions, but because the boy is so young it is considered statutory rape.

Police said the teacher and the teen sent each other 'snap chat' messages of each other's genitalia. They also exchanged explicit text messages.

Investigators said they had collected electronic messages between the pair. Two USB thumb drives, an iPad and two Apple iphones and desktop computer were seized from McCormick's home.

Caught: Another student, aged just 12, found a photo of the teacher wearing just a towel on the boy's phone

Police launched their investigation after a 12-year-old girl friend of the boy borrowed his cell phone and discovered one of the messages which showed the teacher in nothing but a towel, according to 5newsonline.

Further examination of the iPhone revealed a photo of McCormick topless.

The affidavit says an eye witness saw several inappropriate messages and photos, including one with McCormick with wet hair and showing off her breasts.

The text with the risque photo said: 'I'm not dirty anymore.'

McCormick's Facebook page shows she has a husband and a young daughter and reveals her father is a teacher in the same school district.

She has been suspended on full pay and is due before the court again in September.
