A New Jersey teacher who had a sexual relationship with a 17-year-old female student evaded prison time last week after her former students sent letters of support to the court ahead of her sentencing. Ex-Fair Lawn High School graphics arts teacher Christine Knudsen was placed under lifetime parole supervision and forced to register as a sex offender, but won’t see a day behind bars if she doesn’t violate the terms of the sentencing, according to the Bergen Record.
