A 29-year-old woman was accused of enrolling at a New Jersey high school and spending 4 days in classes before anyone noticed

• A 29-year-old woman used a fake birth certificate to enroll in a New Jersey high school this month.
• School officials said the woman spent four days attending classes before she was discovered.

A 29-year-old woman was arrested following her duplicitous stint as a student at a New Jersey high school this month, school officials alleged.

New Brunswick Public Schools officials said an adult woman used fake documents to pose as a student and enroll at a local high school last week where she attended classes and interacted with students for four days before she was caught.

Superintendent Aubrey Johnson said during a Tuesday evening Board of Education meeting that the woman attended some classes while at the school but spent most of her time with guidance counselors who were trying to uncover more information about her.

"This is an unfortunate incident," Johnson said, according to a video clip of the meeting shared by Charlie Kratovil, a journalist with New Brunswick Today.

New Brunswick Police identified the woman as Hyejeong Shin, a resident of New Brunswick, according to NBC News, and told the outlet she was charged with one count of providing a false government document with the intent to verify one's identity; authorities said she produced a fake birth certificate in order to enroll at the school.

New Brunswick Police did not immediately respond to Insider's request for comment.

During the Tuesday Board of Education meeting, Johnson said school officials barred the woman from entering any district property after they "uncovered her ruse" and immediately alerted authorities.

"Similarly, we have questioned all our students, those who encountered this person while she was in our high school," Johnson said. "We also made sure we have told our students not to have any further contact with her, not remotely or in person."

One student told New Brunswick Today that she was still receiving text messages from the woman as recently as Monday, Jan. 23.

Johnson cited New Jersey state statutes that require public schools to enroll "all students that come our way," though districts can later request verifying documents. The superintendent said the district plans to look at its policies in order to better spot fake documentation.

The district did not immediately respond when asked about the woman's possible motives.
