CAMDEN, N.J. (AP) — A fourth person connected to a southern New Jersey high school has pleaded guilty to charges stemming from inappropriate relationships with students.

Former Triton High School teacher Nick Martinelli pleaded guilty Thursday to one count of fourth-degree hindering apprehension.

Martinelli resigned his teaching position and will forfeit his teaching certificate. Under terms of his plea, he will be sentenced to probation next month.

The 28-year-old Martinelli admitted impeding an investigation by telling a student to not tell investigators about their relationship. The Camden County Prosecutor’s Office says Martinelli wasn’t charged with sex offenses because the student was over 18.

Two other teachers and Triton High’s principal have already pleaded guilty. The two teachers are scheduled to be sentenced on Friday.

An official misconduct charge is pending against a vice-principal.
