Leah B. Foley United States Attorney for the District of Massachusetts | Department of Justice
A Guatemalan national living in Framingham was sentenced on March 4 in federal court in Boston for unlawfully reentering the United States after being deported multiple times. Ariel Humberto Diaz, 33, received a sentence of 14 months in prison and two years of supervised release from U.S. District Court Chief Judge Denise J. Casper. Diaz will be subject to deportation after completing his prison term.
Diaz pleaded guilty in October 2025 to one count of unlawful reentry of a deported alien, following an indictment by a federal grand jury in June 2025. The case highlights ongoing efforts by federal authorities to address repeated illegal entries into the country.
According to court records, Diaz was most recently deported from the United States to Guatemala in March 2022. After that removal, he returned illegally without permission. Prior to this incident, Diaz had been removed to Guatemala four other times: May 2014, April 2016, October 2016, and November 2018. He has also been convicted twice before for illegal re-entry offenses in federal court.
The sentencing was announced by United States Attorney Leah B. Foley and Patricia H. Hyde, Acting Field Office Director of U.S. Immigration and Customs Enforcement’s Enforcement and Removal Operations in Boston. Assistant U.S. Attorneys Alexandra W. Amrhein and Jennifer Zacks prosecuted the case.
The case underscores continued enforcement actions against individuals who repeatedly violate immigration laws by returning to the United States after removal.
