Convicted Sex Offender Who Had Been Deported to Mexico Pleads Guilty to Illegally Re-Entering the United States

WASHINGTON – Saul Castillo-Crespo, 28, a citizen of Mexico, pleaded guilty today in U.S. District Court to illegal re-entry into the United States, announced U.S. Attorney Jeanine Ferris Pirro.

Castillo-Crespo, aka “David Crespo,” was previously convicted in August 2017 in D.C. Superior Court and sentenced to five years in prison in connection with the kidnapping and sexual abuse of an intoxicated stranger in Northwest Washington.

In January 2023, Castillo-Crespo was deported to Mexico. He illegally re-entered the country in March 2025, proceeded to violate the law by failing to register as a sex offender, and was arrested in June by local law enforcement.

Judge Timothy J. Kelly scheduled sentencing for March 13, 2026.

“This individual sexually assaulted a victim and got deported a few years ago, just to sneak back into the U.S. illegally,” said U.S. Attorney Pirro. “I will not allow this brazen defiance of our immigration laws to continue, especially from criminals who commit the most heinous illegal acts.”

According to the court documents, ICE learned that Castillo-Crespo had been arrested by MPD officers on June 27, 2025, and had been charged with unlawful entry and destroying property. On arrest, the defendant identified himself using the alias “David Crespo.”

On July 16, 2025, law enforcement fingerprinted “David Crespo.” The FBI identified him as Castillo-Crespo. ICE determined that the fingerprints matched those of a known and previously deported alien.

Castillo-Crespo previously was found guilty and sentenced for a sex crime in the District. On May 7, 2017, Castillo-Crespo encountered his victim in the early morning hours on a sidewalk near Lafayette Square in downtown Washington. The woman was extremely intoxicated, unable to walk, and told Castillo-Crespo that she wanted to go to her home. Castillo-Crespo hailed a passing taxi and took her to his apartment building in the 1700 block of Seventh Street NW. Once inside, the victim refused to enter Castillo-Crespo’s fourth-floor apartment and repeated that she wanted to go home. Castillo-Crespo carried her to a staircase where he sexually assaulted her. His conduct inside the building was captured on building surveillance cameras.

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