HSI San Juan Arrests Two Men on Child Exploitation Charges

SAN JUAN, Puerto Rico – Two men were arrested by Homeland Security Investigations (HSI) on criminal charges related to child exploitation conduct.

On Thursday, December 4, 2025, the Puerto Rico Crimes Against Children Taskforce (PRCACTF) led by HSI, arrested José Antonio Maestre-Rivera, a 27-year-old man from Carolina, PR.

A federal grand jury indicted Maestre-Rivera on December 3, 2025, with five counts of sexual exploitation of children, coercion and enticement of a minor, transportation of a minor with intent to engage in criminal sexual activity, receipt of child exploitation material, and transfer of obscene material to a minor.

According to court documents, from April through October 2025, defendant Maestre-Rivera used electronic devices and internet social media applications to persuade and entice a 14-year-old female minor to engage in sexually explicit conduct. During the same period, Maestre-Rivera produced, received, and transmitted child exploitation material. He also knowingly transported said minor with the intent to engage in sexual activity.

If convicted, the defendant faces a minimum sentence of 15 years and a maximum sentence of up to life in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

In a separate case, Gilberto Fontanez Alvarado, a 67-year-old man from Bayamón, was arrested on December 4, 2025, by HSI agents. A federal grand jury indicted Fontanez Alvarado with two counts of transportation of child exploitation material and possession of child exploitation material.

According to the indictment, from August 2012 through November 2025, the defendant knowingly used electronic devices, for the possession and access with intent to view of images of child exploitation material, including of a prepubescent minor or a minor who had not attained 12 years of age.

If convicted, Fontanez Alvarado faces a mandatory minimum sentence of 5 years and a maximum sentence of 20 years in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

AUSA Emelina M. Agrait-Barreto of the Child Exploitation and Immigration Unit is prosecuting both cases.

“We are committed to bringing child predators, including those charged in these cases, to justice and protecting our children,” said W. Stephen Muldrow, United States Attorney for the District of Puerto Rico. “I would like to thank the federal agents, prosecutors and our state and local partners who are relentless in their efforts to identify and prosecute those who seek to exploit children.”

“These charges highlight a deeply troubling and escalating threat in child exploitation cases: predators who collect and trade images of child sexual abuse material are aggressively using social media platforms to target and groom minors,” said HSI San Juan Acting Special Agent in Charge Yariel Ramos. “In one case, the suspect deliberately initiated contact with a minor through public social media profiles, then swiftly shifted to private direct messages to facilitate their criminal acts. In the other case, our investigation uncovered disturbing evidence of a collection of illicit images demonstrating the long-term and calculated nature of this predatory behavior. These cases serve as a stark warning of the relentless danger posed by online predators. HSI remains unwavering in our commitment to identifying, arresting, and prosecuting these offenders. We urge parents, guardians, and communities to remain alert and proactive in protecting children. HSI will continue to work with our federal and local partners to ensure these criminals are brought to justice.”
