California Man Sentenced for Stalking, Harassing, and Threatening Women in Rhode Island, Massachusetts, and in Other States
PROVIDENCE – A California man who made hundreds of obscene, harassing, and threatening telephone calls to women in Rhode Island, Massachusetts, and other states has been sentenced in federal court in Providence.
Justin Glauthier, 31, of Anaheim, California, was sentenced today by U.S. District Court Judge Melissa R. DuBose to 36 months’ imprisonment, followed by three years of supervised release, and ordered to pay $400 special assessments. Glauthier previously pleaded guilty to four counts of stalking through cellular and internet communications.
According to court documents, Glauthier obtained women’s names, photographs, and other personal information from the internet and used that information to make repeated, unwanted, sexually explicit, and threatening calls.
During dozens of calls to at least nine identified victims, Glauthier, using a false name and hiding his identity by creating voice of internet protocol phone numbers or the *67 function on his phone, made sexually explicit and threatening statements, at times claiming to know where victims lived or worked and threatening to appear at their homes or workplaces if they did not comply with his demands to continue speaking with him or describing the sexual acts he wanted or was planning to do with the victims. On some of the calls, Glauthier would tell victims that he had masturbated to their online photos and would masturbate while on a call with a victim.
An investigation conducted by the Federal Bureau of Investigation (FBI) Providence Resident Agency and FBI’s Orange County, California, Resident Agency linked the calls to Glauthier, who was arrested in Anaheim on March 5, 2025.
“Glauthier believed he could hide behind a phone and inflict fear without consequence,” said First Assistant U.S. Attorney Charles C. Calenda. “He was wrong. The federal system held him accountable, and we will continue to aggressively pursue anyone who thinks they can use digital tools to terrorize vulnerable victims.”
“Justin Glauthier was a prolific, persistent, and pernicious cyber predator who relentlessly taunted and tormented dozens of victims with sexually explicit and threatening calls, and deliberately took steps to hide his identity,” said Ted E. Docks, Special Agent in Charge of the FBI’s Boston Division. “We are especially grateful to the courageous victims who came forward—they’re willingness to speak up enabled the FBI to identify Glauthier and ultimately stop this incessant harassment. Today’s sentence should serve a lesson to anyone who attempts to inflict this type of cruelty on others: the FBI will find you and will ensure you are brought to justice.”
The case was prosecuted by Assistant United States Attorney Denise M. Barton for the District of Rhode Island, with assistance from Assistant United States Attorney Lauren Restrepo of the Central District of California.
The matter was investigated by the Federal Bureau of Investigation.
