Lisa Marinelli, a former Pasco County substitute teacher accused last year of having a sexual relationship with a student, pleaded guilty in court this morning.

She faced up to 15 years in prison but avoided any time behind bars. Instead, prosecutors and her defense attorney agreed to a stringent probationary sentence that includes a year of house arrest and no contact with children under 18 without supervision.

The married mother of two will have to register as a sex offender, undergo testing for sexually transmitted diseases and complete sex offender treatment.
