David X. Sullivan, United States Attorney for the District of Connecticut, announced that CESAR RUBEN YLLESCAS, 52, a citizen of Peru, was sentenced today by U.S. District Judge Michael P. Shea in Hartford to 15 months of imprisonment for illegally reentering the U.S. According to court documents and statements made in court, between 1995 and 2015, Yllescas was arrested, convicted, and sentenced multiple times in Connecticut Superior Court and Chicopee, Massachusetts District Court for narcotics offenses, threatening, assault, failure to appear in court, and illegal operation of a motor vehicle. In June 2016, Yllescas was deported to Peru. He subsequently reentered the U.S., was convicted in federal court of unlawful reentry and, in December 2019, was sentenced to 10 months of imprisonment. In May 2020, Yllescas was again deported to Peru.
Yllescas again illegally reentered the U.S. and, on March 20, 2026, he was arrested by the West Springfield, Massachusetts Police Department for motor vehicle-related charges and on an outstanding warrant for failure to appear in court in 2015 for a violation of probation. After Yllescas was released on bond on those state charges, he was arrested by ICE Enforcement and Removal Operations on March 23, 2026, in West Springfield.
Yllescas has been detained since his arrest. On June 23, 2026, he pleaded guilty to unlawful reentry of a removed alien.
This matter was investigated by U.S. Immigration and Customs Enforcement (ICE), Enforcement and Removal Operations. The case was prosecuted by Assistant U.S. Attorneys Neeraj N. Patel and Michael S. Deel.
This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.
