A Palm Beach Gardens man has been sentenced to 127 years in Florida state prison after Stuart Police say he traveled to meet a minor he had targeted for sexual exploitation online. Phoenix Monserrate, who was 22 at the time of his arrest, was convicted on multiple charges involving sexual exploitation of a child and possession of child sexual abuse material, closing out a case that began with a mother's discovery of disturbing messages on her child's phone.
According to WPEC, the investigation traces back to when the juvenile's mother contacted Stuart Police about messages she found on her child's phone. Per an earlier account from Atlántikas Noticias, Stuart Police detectives launched the investigation on September 11, 2024, after the mother brought the device directly to local police, and detectives went on to review social media accounts and text messages to identify the suspects.
Cross-Country Trip Led to Arrest
Monserrate was arrested on more than a dozen charges, including 10 counts of possessing or viewing depictions of child sexual conduct and five counts of promoting sexual performances by a child, per WPEC. He was taken into custody after traveling to Stuart expecting to meet the juvenile victim, and the same Atlántikas Noticias report states he was arrested on November 19, 2024, and held in the Martin County Jail on a $1,000,000 bond. Stuart Police announced his arrest in December 2024, and detectives who worked with Homeland Security Investigations in Fort Pierce ultimately built the case that led to his conviction and sentencing in Stuart.
Detectives identified three men total who provided or offered tobacco, alcohol and other gifts to the juvenile, with police saying the gifts were apparently intended to establish a relationship with the child, according to WPEC. The Stuart Police Department has said it remains committed to protecting children and holding predators accountable, and it credited the state attorney's office for prosecuting Monserrate.
Two Other Men Named in the Case
Robert Green, 51, of Fort Pierce, was the first of the three suspects arrested, taken into custody on October 3, 2024, according to the Atlántikas Noticias account, for communicating with the minor via Snapchat and phone and traveling to Stuart to provide a vape device to the child. Green was convicted of providing tobacco products to the child and was later adjudicated guilty, the outlet reported.
The third man named in the case, Austin Lanyon, was a Tampa firefighter at the time, per WPEC. He was arrested in Tampa on December 12, 2024, and held at the Hillsborough County Jail on a $220,000 bond, according to FOX 13 Tampa Bay. Lanyon faced allegations including unlawful use of a two-way communication device, transmitting harmful material to a minor, and lewd solicitation of a child. Following his arrest, Tampa Fire Chief Barbara Tripp issued a statement suspending Lanyon and declaring that his alleged conduct violated the core oath and values of firefighters, according to the same FOX 13 report, which noted Lanyon had worked for Tampa Fire Rescue since 2022.
How Prosecutors Stacked the Charges
Monserrate's 127-year sentence reflects how Florida law allows prosecutors to build cumulative, decades-long prison terms. Under Florida Statutes § 827.071, each individual image, video file, or sexual performance presentation involving a minor constitutes a separate criminal count, a mechanism Hoodline has previously reported lets state attorneys stack felony charges file by file.
The case also arrives amid a broader shift in Florida law. Under House Bill 245, effective July 1, 2026, state statutes officially replaced all legal references to child pornography with the term child sexual abuse material to better reflect the abuse depicted. Separately, House Bill 445, known as Missy's Law and also effective July 1, 2026, added computer pornography and digital child exploitation to Florida's statutory list of dangerous crimes, restricting nonmonetary pretrial release and mandating immediate custody without bond upon conviction.
A Regional Problem Beyond One Case
The Stuart case is one small piece of a much larger volume of digital exploitation leads flowing through Florida law enforcement. Law enforcement agencies across the state received and processed more than 47,500 actionable CyberTipline reports of digital child exploitation from the National Center for Missing & Exploited Children in 2023, with tips routed to regional Internet Crimes Against Children task forces across 61 jurisdictions nationwide.
The Stuart Police Department maintains a dedicated team of specialized detectives who work alongside the regional ICAC Task Force and federal Homeland Security Investigations agents to combat online child exploitation on the Treasure Coast, according to a department statement posted to Facebook. That coordination between local, state, and federal agencies was central to identifying all three men connected to the case involving the Stuart juvenile.
