WASHINGTON – Saul Castillo-Crespo, 28, a citizen of Mexico, has been charged in an indictment, unsealed today in U.S. District Court, with violating the Sex Offender Registration and Notification Act (SORNA) and illegal re-entry into the United States, announced U.S. Attorney Jeanine Ferris Pirro.
Castillo-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.
“This defendant has repeatedly crossed the border illegally to commit multiple crimes in the District of Columbia,” said U.S. Attorney Pirro. “He’s a poster boy for the kind of threat that we are determined to remove from our community.”
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.
On May 7, 2017, Castillo-Crespo found the victim in the early morning hours on a sidewalk near Lafayette Square in downtown Washington. She 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 brought her back 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. On multiple occasions, she fell and laid down on the hallway floor due to her intoxication. She tried to push Castillo-Crespo away and return to the elevator to leave the building, but Castillo-Crespo blocked her and pulled her back toward his apartment. Because of the commotion this was causing in the hallway, Castillo-Crespo lifted her and carried her to the fourth- floor staircase, where Castillo-Crespo 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 and Kyle McWaters.
