Mexican National Sentenced for Illegal Reentry after Deportation

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Camela C. Theeler has sentenced a Mexican man convicted of Illegal Reentry after Deportation. The sentencing took place on March 10, 2025.

Celso Diaz-Martinez, 52, was sentenced to time served and ordered to be removed from the United States.

Diaz-Martinez was indicted for Illegal Reentry after Deportation by a federal grand jury in November 2024. He was found guilty following a federal jury trial on February 18, 2025.

The evidence at trial established Diaz-Martinez is not a U.S. citizen and had been deported from the United States on four prior occasions. Diaz-Martinez was found in Meade County, South Dakota, in November 2024.

This case was investigated by the U.S. Department of Homeland Security Immigration and Customs Enforcement and the Meade County Sheriff’s Office. Assistant U.S. Attorneys Anna Lindrooth and Benjamin Schroeder prosecuted the case.

Diaz-Martinez was immediately remanded to the custody of the U.S. Marshals Service.
