Sex Offender Who Had Been Deported to Mexico Sentenced to 30 Months for Illegally Re-Entering the United States

WASHINGTON - Saul Castillo-Crespo, 28, an illegal alien from Mexico and a previously convicted sex offender, was sentenced today to 30 months in federal prison for illegally re-entering the United States after deportation, announced U.S. Attorney Jeanine Ferris Pirro.

"Saul Castillo-Crespo committed a brutal sexual assault against a defenseless woman on the streets of the District, was deported after serving his sentence, and then illegally returned to the United States," said U.S. Attorney Pirro. "He apparently believed that using a new name would make him invisible. He was wrong. Following his prison sentence, he will again be deported."

Castillo-Crespo pleaded guilty on Jan. 8, 2026, before U.S. District Court Timothy J. Kelly to one count of unlawful re-entry of a previously deported alien. In addition to the 30-month prison sentence, Judge Kelly ordered Castillo-Crespo to serve three years of supervised release and to submit to any deportation order.

According to court papers, on May 7, 2017, Castillo-Crespo encountered a woman in the early morning hours on a sidewalk near Lafayette Square in downtown Washington. The woman was extremely intoxicated and unable to walk on her own. She told Castillo-Crespo she wanted to go home. Instead, Castillo-Crespo hailed a cab and took her to his apartment building in the 1700 block of Seventh Street NW.

Once inside, the woman refused to enter Castillo-Crespo's fourth-floor apartment and repeated that she wanted to go home. Castillo-Crespo carried her to a staircase and sexually assaulted her. The assault was captured on the building's surveillance cameras.

In August 2017, Castillo-Crespo was convicted in D.C. Superior Court and sentenced to five years in prison for the kidnapping and sexual assault.

In January 2023, Castillo-Crespo was deported to Mexico. Two years later, he illegally re-entered the United States in March 2025 and failed to register as a sex offender as required by law.

On June 27, 2025, Metropolitan Police Department officers arrested Castillo-Crespo on unrelated charges. Although he initially identified himself to officers using the alias "David Crespo," law enforcement fingerprinted him after his arrest, which confirmed his true identity. U.S. Immigration and Customs Enforcement also confirmed that his fingerprints matched those of a previously deported alien.

This case was investigated by U.S. Immigration and Customs Enforcement and the Metropolitan Police Department. It was prosecuted by Assistant U.S. Attorney Joshua Satter.
