November 3, 2008 - Brian Coar, 25, a Whippany Park High School math teacher, pleaded guilty to child endangerment for an inappropriate relationship with a 17-year-old student. (picture at story.)

The charge will be dismissed once he completes three years in a pre-trial intervention program and does 200 hours of community service. Coar surrendered his teaching certificate and promised never to pursue a job in education.

Coar's attorney tried unsuccessfully to get Superior Court Judge Thomas V. Manahan to rule Coar's guilty plea could not be used in a civil case. The family of the girl have filed a notice of intent to sue.

Coar worked at the high school only for the 2007-08 school year.
