A school nurse in Maryland faces charges after she allegedly admitted to performing oral sex on several students, according to officials.

Samantha Marsh, who works at Crisfield High School & Academy, was arrested Tuesday following allegations she had sexual encounters with four students in the back of her van, news station WBOC reported.

The 33-year-old nurse is accused of being sexually involved with the students off-campus between March 2018 and January 2019.

Detectives spoke to the four victims who stated Marsh picked them up from school in her van. The alleged sex acts occurred in the vehicle at various locations in Crisfield, they said.

Marsh reportedly confessed to engaging in oral sex with at least three of the students.

She was booked on multiple sex offense charges and is being held without bail at the Somerset County Detention Center.

Crisfield High School & Academy said they placed Marsh on paid administrative leave prior to her arrest, news station WBOC reported.
