ALBANY — A woman faces up to three years in prison after pleading guilty Tuesday to pretending to be an attorney, defrauding over 400 New Yorkers, according to the state Attorney General's office.

Antonia Barrone, also known as Mario Vrendenburg, pleaded guilty to felony scheme to defraud, Attorney General Eric Schneiderman said in a news release.

Barrone, who made use of multiple names, was born male, but identifies as female. Barrone must pay back the clients who were promised representation in legal matters, including parole appeals, plus state penalties, totaling nearly $270,000.

Barrone operated under the New York State Prisoners Assistance Center or New York Parole Aids, advertising an array of legal services and charging thousands of dollars. Despite not being a licensed attorney, Barrone filed administrative and judicial appeals on behalf of inmates who were denied parole by the state Department of Corrections and Community Supervision and represented inmates at administrative hearings and individuals facing criminal charges in courts. In some cases, Barrone was paid but did not perform any services.

She collected thousands of dollars in legal fees since at least 2012, Schneiderman said. She also filed legal documents with forged signatures and fake notary stamps, and wrote letters to consumers on letterhead bearing a fictitious law firm, Stacchini & Barrone.

Victims of the fake attorney scheme included residents in Albany, Rensselaer, Saratoga and Warren counties, among others across the state.

Barrone is scheduled to be sentenced Nov. 16 to one to three years in state prison, which will run consecutive to her sentence of 1 1/3 to four years in prison for an unrelated felony conviction, Schneiderman said. She will be place in a female prison to serve her sentence, officials said.
