MADISON, WIS. – Chadwick M. Elgersma, United States Attorney for the Western District of Wisconsin, announced the conclusion of a year-long effort that focused on prosecuting individuals who were unlawfully in the district and posed threats to community safety.

An alien commits a federal crime when that person reenters the United States without permission after having been previously removed or deported. 

Since October 2025, the U.S. Attorney’s Office has charged 125 aliens with illegally reentering the United States. To date, law enforcement agencies have located and arrested 87 of the 125 individuals. Notably, 38 of the 87 arrestees had prior federal convictions, underscoring the emphasis on repeat offenders and those with criminal histories or pending criminal charges. To date, immigration authorities have deported 85 of the 87 arrestees.

Below are examples of defendants who were convicted:

  1. Alfredo Juarez-Perez

On July 8, 2026, Juarez-Perez, a citizen of Mexico, was sentenced by U.S. District Judge William M. Conley to 54 months in federal prison for illegally reentering the United States. Juarez-Perez has a long history of criminal and immigration violations in both Wisconsin and Texas, including multiple federal convictions for illegal reentry after removal, as well as state convictions for sexual assault and operating while intoxicated (OWI) offenses. In November 2011, Juarez-Perez was convicted in the Western District of Wisconsin and sentenced to 78 months in prison for possessing cocaine with intent to deliver. He was also arrested by the DeForest Police Department in 2025 for a sex offender registry violation.

  1. Samuel Baleon-Rivera

Judge Conley sentenced Baleon-Rivera, a Mexican citizen, to 52 months in prison on May 21, 2026, for illegally reentering the United States. Baleon‑Rivera’s criminal history includes being charged with hit and run involving injury and operating while revoked. He also has multiple OWI convictions dating back to 2008, including a November 2018 Dane County conviction for OWI (7th, 8th, or 9th). In 2014, Baleon-Rivera was convicted in the Southern District of Texas and sentenced to 30 months in federal prison for illegally reentering the United States. He received an additional 14 months in prison after his supervised release was revoked in 2021. Baleon-Rivera has been removed from the United States five previous times. 

  1. Pablo Delgado-Zetina

Delgado‑Zetina is a citizen of Mexico who has numerous criminal and immigration-related incidents in the United States. Between 2013 and 2026, he was convicted of several offenses in Wisconsin, including battery with a domestic abuse modifier, OWI (2nd and 3rd offenses), and Disorderly Conduct with a domestic abuse modifier. He was also removed to Mexico three times prior to December 2025. Despite those removals, Delgado‑Zetina illegally returned to the United States twice and was prosecuted both times. On April 22, 2026, Western District of Wisconsin Chief U.S. District Judge James D. Peterson sentenced Delgado‑Zetina to time served for illegally reentering the United States. Once again, immigration officials deported Delgado-Zetina from the United States, but he was arrested in New Mexico on August 3, 2026, for another reentry offense. Delgado-Zetina’s sentencing in the District of New Mexico is scheduled for October 26, 2026.

  1. Luis Roberto Pullaguari-Lozano

Pullaguari-Lozano faced criminal charges across several Wisconsin counties between 2025 and 2026, including battery with a domestic abuse modifier, disorderly conduct, OWI, neglecting a child, operating while revoked, criminal damage to property, and multiple counts of bail jumping. He had also been previously removed from the United States before being arrested in the Western District of Wisconsin in December 2025. On October 16, 2026, Judge Peterson sentenced Pullaguari‑Lozano to time served for illegally reentering the United States. 

  1. Fernando Ivan Llamas

Llamas, 35, a citizen of Mexico, was sentenced yesterday by Judge Peterson to 32 months in federal prison for illegally reentering the United States. Llamas pleaded guilty to this charge on July 21, 2026. On November 9, 2025, law enforcement arrested Llamas in Verona, Wisconsin, for operating a motor vehicle while intoxicated and battery. Llamas also had an outstanding warrant for fleeing and eluding law enforcement. Llamas has previously been deported from the United States five times and has four prior criminal convictions for illegal reentry.

At sentencing, Judge Peterson considered that Llamas was first brought to the United States as a young child, which was a circumstance beyond his control. Judge Peterson weighed this factor against Llamas’s repeated illegal reentries into the United States and his criminal history while in the United States, which involved conduct that posed a danger to the public. Ultimately, Judge Peterson explained that he imposed this sentence as a vigorous message of deterrence to not return to the United States.

U.S. Attorney Elgersma emphasized that although the operation has concluded, ongoing investigations and prosecutions will continue to ensure that individuals who endanger public safety are identified and brought to justice.
