Two Illegal Immigrants Arrested in Montgomery County Child Sex Assault Case

Detectives with the Montgomery County Sheriff’s Office Special Victims Unit have arrested two men, identified as David Rey Santoyo-Penaranda and Gary Morales-Alarcon, following an investigation into the sexual assault of a 14-year-old female.

In March 2025, the SVU began investigating disclosures made by the victim, which led to the identification of Santoyo-Penaranda as the initial suspect. During the investigation, Santoyo-Penaranda confessed to the assaults, and detectives located physical evidence. He was arrested and charged with Sexual Assault of a Child, a second-degree felony.

Further forensic interviews with the victim at Children’s Safe Harbor revealed additional instances of sexual abuse by Morales-Alarcon, leading to the issuance of an arrest warrant for him on the same charge.

Authorities have confirmed that both Santoyo-Penaranda and Morales-Alarcon are in the United States illegally. Upon their arrest, the United States Immigration and Customs Enforcement (ICE) was notified, and ICE detainers have been issued for both individuals.

The Montgomery County Sheriff’s Office expressed its appreciation to Children’s Safe Harbor, TxFNE, the Montgomery County District Attorney’s Office, and the Montgomery County Multidisciplinary Team for their support in this case, emphasizing their commitment to seeking justice for child victims.
