NJ Teacher/Coach Admits Sexual Affair With Teen, Colleague Also Busted

A former Somerset County teacher is heading to state prison after pleading guilty to sexually assaulting a student.

Matthew Rennie, of Ringoes, had been working as a teacher and coach at a private educational institution in Franklin Township, when he sexually assaulted a 17-year-old female, the Somerset County Prosecutor’s Office said.

Sexually assaulted for months

The victim reported she was sexually assaulted by Rennie in Montgomery and in East Amwell from July to September of 2021.

Investigators also charged a fellow teacher and coach, Ranait Griff, 30, of South Orange, with being aware of the relationship but not reporting Rennie to the authorities.

She was arrested at the Franklin Township Police Department and has been indicted on fourth-degree charges of failure to report child sexual abuse.

Rennie was indicted on second-degree charges of sexual assault and third-degree child endangerment.
