California Man Pleads Guilty to Stalking, Harassing, and Threatening Women in RI, MA, and Elsewhere

PROVIDENCE - A California man has pleaded guilty in federal court in Rhode Island to charges related to a scheme in which he made hundreds of obscene and threatening telephone calls to women in Rhode Island, Massachusetts, and elsewhere, announced United States Attorney Charles C. Calenda.

Justin Glauthier, 30, pleaded guilty to four counts of stalking through cellular and internet communications. He is scheduled to be sentenced on August 6, 2026. The sentence imposed will be determined by a federal district court judge after consideration of the U.S. Sentencing Guidelines and other statutory factors.

According to court documents, Glauthier repeatedly called and harassed women whose names, photographs, and other personal information he obtained from the internet.

At the time of his arrest, at least nine women had been identified as receiving harassing and threatening phone calls that a Federal Bureau of Investigation (FBI) investigation determined were made by Glauthier. In dozens of calls to victims, Glauthier made sexually explicit comments, sometimes claimed to know where they lived and/or worked, and threatened to visit them unannounced at their homes or places of employment if they did not remain on the phone with him or cooperate during the calls.

Glauthier was arrested in Anaheim, California on March 5, 2025, by agents from the FBI's Providence and Orange County, California, Resident Agencies.

The case is being prosecuted in the District of Rhode Island by Assistant United States Attorney Denise M. Barton, with the assistance of Assistant United States Attorney Lauren Restrepo in the District of Central California.

The matter was investigated by the FBI.
