The 32-year-old former Department of Children and Families social worker who posed as a student at three BPS high schools is facing criminal charges, according to a criminal complaint.

The charges come just over a week after BPS Superintendent Mary Skipper informed families at Burke, Brighton and English high schools that an adult had fraudulently enrolled in the schools over the 2022-23 school year and was being investigated by police.

The police’s criminal complaint, filed in West Roxbury District Court on Tuesday, identified the woman as Jamaica Plain-resident Shelby Hewitt and listed criminal charges including forgery, identity theft and others in relation to the BPS fraud. Police requested a warrant for her arrest in the document.

Hewitt — using the alias “Ellie” — was found out on June 14 when a man posing as her “foster father” announced she would be leaving English High School less than a week after she transferred there, sending up red flags for school administrators.

A staff member looked into and found an error in her enrollment paperwork, then discovered a listed social worker did not exist and notified police, the incident report stated.

Initial evidence showed Hewitt, along with John Smith and Rebecca Bernat, two 48-year-old adults living with her and posing as her “foster parents,” pulled off what Skipper called an “extremely sophisticated fraud.”

It is not clear what, if any, charges will be brought against Smith and Bernat.

Authorities also confirmed that Hewitt had worked as a social worker for DCF until February 2023.

Though police have investigated the situation from a human trafficking angle, Mayor Wu said on WGBH Sunday, there has been no evidence yet that Hewitt harmed students at the schools.

Investigators with the BPD Human Trafficking, BPD Internet Crimes Against Children and State Police High-Rick Victims units, executed a search warrant for Hewitt’s apartment last week, a BPD report stated.

The search found “falsely made, altered, or forged” documents from the Lowell Juvenile Court and DCF in Hewitt’s bedroom, according to the report.

The court documents used the name of a person identified through the Lowell Juvenile Court staff, who said she did not know Hewitt and did not give her permission to use her identity, the police report said.

Hewitt, the document states, used false premises to attend BPS schools from Sept. 7, 2022, to June 14, 2023.

The warrant was requested, the complaint reads, “because prosecutor represents that accused may not appear unless arrested.”

The court documents did not indicate any potential motives into Hewitt’s actions.
