CHARLES COUNTY, Md., June 20, 2025 — Authorities arrested Franklin Argueta-Marquez, 28, on May 29 in Charles County, Maryland, after he was indicted on two counts of rape and sexual offense involving a 13-year-old girl. The suspect, who has no fixed address, initially contacted the victim through a social media app when she was 12. After weeks of messaging, he persuaded her to sneak out of her home, where he sexually assaulted her in his car. The case came to light when a parent alerted police, leading to an investigation that identified Argueta-Marquez.
On March 14, 2025, a Charles County Grand Jury indicted Argueta-Marquez on charges related to the assault, citing the victim’s age. An arrest warrant was issued, but the suspect had fled the country. He was apprehended by Arizona authorities upon his return to the United States and extradited to Charles County. The investigation, led by PFC T.C. Rickard, Jr. and Detective Singh, revealed that Argueta-Marquez drove a dark-colored sedan, possibly a Toyota Corolla, during the incidents. He previously resided in Beltsville, Maryland.
Sheriff Troy D. Berry emphasized the importance of parental vigilance in online safety. “Keeping your child safe online is just as important as their safety in the real world. Regularly checking their cell phone and computer activity, including social media, can help prevent cyberbullying, online predators, and exposure to harmful content,” said Sheriff Berry. He urged parents to discuss internet safety with their children and monitor their online interactions closely.
Authorities provided guidance for parents to protect children from online predators. Recommendations include knowing children’s passwords and logins, setting screen time rules, discussing internet safety, using parental control tools, and following children on social media when appropriate. Parents should also watch for warning signs such as sudden secrecy about online activity, behavioral changes, late-night device use, or messages from unknown contacts.
No additional victims have been identified, but police encourage parents to talk with their children about any interactions with Argueta-Marquez. Individuals with information or who may have been affected are asked to contact Detective Singh at 301-609-6471. The investigation remains ongoing as authorities ensure all leads are pursued.
The case underscores the dangers of online interactions for minors and the critical role of parental oversight. Sheriff Berry’s office continues to advocate for proactive measures to safeguard children in digital spaces. Resources for online safety are available through local law enforcement and community organizations, offering tools to help families navigate the challenges of internet use.
