A 32-year-old New York woman apparently pretended to be a homeless high school student, and enrolled in classes and rode the school bus with other students in December.

CBS13 reports that Michaelann Goodrich is accused of lying about her age and enrolling into Cairo-Durham High School in Cairo, where she told school administrators she was 15. According to the Green County Sheriff’s Office, Goodrich registered under the name Riley Madison and claimed she was homeless.

Under the federal McKinney-Vento Act, the Cairo-Durham school district is required to automatically register and enroll homeless students.

District superintendent Anthony Taibi told NBC News he saw “red flags” and asked police to look into the matter. It’s unclear what details alarmed Taibi, but he indicated “there was enough in her story that caused some concern.”

Goodrich attended one day of class at the high school, riding the bus to and from school on December 2o. She didn’t show up for classes on December 21, reportedly claiming she had an appointment that day.

The following day, Christmas break began, and authorities began investigating the incident. Senior Investigator with the Greene County Sheriff’s Department, Joel Rowell, said that detectives determined through investigative work that Goodrich was already a high school graduate. Police are now trying to figure out the motive behind the suspect enrolling in high school.

“She could’ve gone in numerous different ways to obtain a degree and we actually found out through the investigation and that she has a high school diploma,” Rowell said. “So that just leads to our investigation to try to figure out what exactly her motive was for attending school.”

Police arrested Goodrich on December 28 and charged with criminal trespassing, offering a false instrument for filing, and falsifying business records. Her bond was set $10,000.

This is an active case. Investigators ask anyone who had contact with Goodrich to call the Greene County Sheriff’s Office at 518-943-3300.
