MARION COUNTY, Fla. – A 64-year-old man was arrested Monday on charges of lewd or lascivious molestation and eight counts of lewd or lascivious battery involving a victim who was between 12 and 16 years old, the Marion County Sheriff’s Office said.

Juan Carlos Quintero-Barrios, 64, Deputies responded June 10 after a juvenile reported that the alleged abuse, which she said began in September 2025, occurred at several locations around Marion County, including Doghouse Boxing Gym, 4 Kings Boxing Gym, Juan Carlos Quintero-Barrios’ home, a hotel room and his vehicle, the sheriff’s office said.

Quintero-Barrios acknowledged that he was the victim’s coach and called her a “troublemaker,” then became agitated when confronted with the allegations and hotel receipts obtained by investigators, the sheriff’s office said.

He admitted to sneaking a female into a hotel room and said it was to cheat on his wife but declined to identify her, investigators said.

Quintero-Barrios was booked into the Marion County Jail and is being held without bond.

Because Quintero-Barrios worked as a boxing coach with children, detectives said they believe there may be additional victims. Anyone with information is asked to contact Detective Zachary Elliot at (352) 368-3847.
