Michael Lentz, a registered sex offender from Lee County who was already on federal probation, is back behind bars after Boynton Beach police said he tried to pay for sex with someone he believed was a 15-year-old. Investigators said the initial contact happened on the Grindr app and continued even after the other person clearly stated their age. Lentz was taken into federal custody and later charged in the Boynton Beach case, according to police.
Undercover Grindr Sting Leads To Charges
According to CBS12, the investigation started when Lentz reached out to an undercover Boynton Beach detective on Grindr. Police said the detective made it clear he was posing as a 15-year-old, yet the conversations continued and Lentz allegedly arranged a meeting. CBS12 reports Lentz was taken into federal custody on May 13 and formally charged in the Boynton Beach case on May 20. Police said attorney information for Lentz was not immediately available.
Boynton Beach Task Force No Stranger To These Stings
The arrest lines up with how the city’s Human Exploitation Task Force typically operates, using undercover online profiles to catch adults who try to meet minors. As WPBF reported, the unit has logged numerous arrests since it launched and focuses on confirming that a suspect understands the supposed victim’s age before making an arrest. Police officials have repeatedly urged parents to keep an eye on unfamiliar apps and conversations on their children’s phones.
Apps, AI And A Growing National Problem
Groups that track online child exploitation say the problem on social and dating apps is getting worse, not better. The National Center for Missing & Exploited Children’s review of 2025 data shows sharp jumps in CyberTipline reports, including categories such as online enticement and AI-related activity, according to NCMEC. Law enforcement agencies point to those numbers when explaining why undercover operations remain a priority. Local detectives say app-based chats can speed up grooming behavior and cut down the time investigators have to step in.
Legal Implications
Police said Lentz was on federal probation for a prior conviction tied to possession of child sexual abuse material. The new allegations could trigger separate federal action or a probation revocation, authorities and court guidance note. Courts can hold revocation hearings and impose penalties that range from tighter supervision to incarceration, according to guidance from the U.S. Courts.
Boynton Beach police say the investigation is still active and are asking anyone with information to contact their investigators. For contact details, residents can visit the Boynton Beach Police Department’s official website. Parents and app users are urged to review available safety resources and report any suspicious messages or contacts to local law enforcement or the National Center for Missing & Exploited Children.
