SAN ANTONIO (KTSA News) — A Venezuelan national is now convicted on five counts related to the sex trafficking of a 16-year-old starting in Columbia and extending to Richmond, Kentucky and San Antonio, announced U.S. Attorney for the Western District of Texas, Justin R. Simmons.
A federal jury handed down the conviction on Monday.
According to court documents and evidence presented at trial, Nelson Adrian Perez-Martinez, 23, harbored, provided, transported, obtained, advertised, and maintained a 16-year-old undocumented Venezuelan orphan.
Co-conspirator Giannys Alexandra Ramirez-Fernandez, 21, began a relationship with the girl when the child was 13 years old and living with her adopted parents in Colombia. The two crossed illegally into the United States in December 2022, residing in Richmond, Kentucky.
Perez-Martinez, a friend of Ramirez-Fernandez from Venezuela, crossed illegally into the U.S. in December 2023 and joined them in Kentucky in June 2024. Perez-Martinez and Ramirez-Fernandez decided to take their victim to San Antonio where they would have her engage in prostitution. Perez-Martinez and Ramirez-Fernandez intended to keep any money she earned.
The three traveled via bus in July 2024 from Richmond to San Antonio for that purpose.
“When we tolerate the stolen innocence of children, we slowly lose our soul as a nation,” said U.S. Attorney Justin R. Simmons. “In the Western District of Texas, we have zero tolerance for aliens who enter our country illegally and commit heinous crimes like those committed in this case. We will use all resources available to us to hold accountable those, like the defendant here, who seek to enrich themselves via the sexual abuse of children.”
An investigation revealed that Perez-Martinez and Ramirez-Fernandez accompanied the minor to approximately six different motels in San Antonio from July 19 to July 30, 2024. The three shared a room at each location, paid for in cash by proceeds from the child’s commercial sex acts.
On Oct. 1, 2025, Perez-Martinez was charged in a five-count indictment with aiding and abetting the sex trafficking of children, aiding and abetting the benefitting from sex trafficking of children, conspiracy to sex traffic children, aiding and abetting coercion and enticement of a minor, and transportation of a minor with intent to engage in criminal sexual activity. The fees collected from the minor’s commercial sex acts were knowingly used by Perez-Martinez and Ramirez-Fernandez for food, shelter, transportation, and other items. The two conspirators lived solely off of the proceeds for approximately six weeks.
Perez-Martinez and Ramirez-Fernandez were arrested on July 30, 2024, as part of an ongoing investigation into domestic sex trafficking. An undercover San Antonio Police officer with the Human Exploitation Unit responded to an advertisement posted on a website for escort services. Posing as a customer, the officer contacted the phone number on the advertisement and was instructed to meet at the Studio 6 motel on Pasteur Court in San Antonio. Once the undercover was in the motel room with the minor, the girl agreed to prostitution services, and the officer signaled for the arrest team. Simultaneously, Perez-Martinez and Ramirez-Fernandez were arrested, as they were identified as spotters for the operation.
