Teacher Lindsay Massaro admits to having sex with boy, 15

A New Jersey Elementary school teacher has admitted to sexual liaisons with a former pupil.

Lindsay Massaro, 25, pleaded guilty to second degree sexual assault on a 15-year-old boy at Frankford Elementary School.

The sexual encounters included trysts in her car and in her bedroom, a court heard.

The assault came to light after his father reported the case to the police.

Before entering her plea bargain, Judge Peter Conforti asked Massaro: 'Do you realise that it is almost certain you will be sentenced to state prison? Is that clear?'

Her voice cracking, she replied, 'yes'.

As part of a plea bargain agreement, Massaro pleaded guilty to one count of second-degree sexual assault on the understanding prosecutors will recommend a four-year prison sentence with parole supervision for life.

The latest  teacher-pupil sex incident follows the arrest last week of 32-year-old gym teacher Stacey Schuler who was charged with having sex with five of her pupils.

The teens were members of the school football team in Dayton, Ohio.

And yesterday a Michigan high school teacher Heidi Lewis was accused of  three-in-a-bed sex with pupils after being summoned to the house of a 17-year-old she had been seeing.

Massaro is scheduled to be sentenced on April 15, pending the outcome of a psychological evaluation to determine if there was a 'patte of repetitive and compulsive behaviour,' the judge said.

If she is found to be a compulsive offender, Judge Conforti said she would be sentenced to a treatment centre and her release would have to be approved by the state parole board.

'You could spend more time in treatment than in state prison,' the judge told her.
