A former Lakewood High School English teacher is expected to be sentenced to three years in state prison and ordered to register as a sex offender for life after pleading no contest to one count of a lewd act upon a child Friday.

Mary Jahn, 53, was arrested in September 2017 after a former student said Jahn sexually abused her for years, starting in 2009 when the student was 15 years old.

The victim, now 25, testified in May that she and Jahn had a sexual relationship for three years, according to the Press-Telegram. She alleged Jahn introduced her to sexual acts involving bondage, hot wax and carving her initials into the victim’s hip.

The victim came forward about the abuse in May 2017, Deputy District Attorney Troy Davis said.

The case was expected to go to trial Friday, but Jahn entered the no-contest plea before it could begin. Jurors were waiting outside the courtroom while Judge Laura Laesecke accepted the plea agreement.

Jahn originally faced up to eight years and four months in prison when she was charged with nine felony counts, all of which she pleaded not guilty to in September, saying she “staunchly denied” the charges.

According Davis, the plea agreement was reached in part to avoid putting the victim through testifying at trial. The state will drop the eight other charges Jahn was facing.

Her attorney, Leonard B. Levine, declined to comment after the proceedings. Jahn is scheduled to be sentenced on Nov. 30.
