A 37-year-old man is behind bars after deputies say he slipped into a northwest Miami-Dade apartment before dawn Thursday and touched a sleeping 13-year-old boy. The child screamed, his parents rushed in, and the family allegedly tackled and held the intruder until deputies showed up. Authorities say the man later admitted he had no permission to be inside and acknowledged touching the boy.
What deputies say
According to Local10, the suspect, identified as 37-year-old Karl Heinz Mercier, walked into a unit at the Park Towers complex on Northwest 155th Lane at about 4 a.m. Deputies say Mercier lay down on the boy's bed while the teen slept and put his hand inside the child's underwear, fondling him. The boy's parents told deputies they had never met Mercier and had not given him permission to enter their home.
Arrest, charges and custody
When the boy screamed, his parents rushed to the bedroom and confronted the man as he tried to get away, then detained him until deputies arrived, Local10 reports. Investigators say Mercier confessed to going into the apartment without permission and to touching the child, and that he told the boy, "Nothing is going to happen. No one is going to come." He was booked on charges of burglary with assault or battery and attempted sexual battery on a minor and was being held at the Turner Guilford Knight Correctional Center with bond listed as "to be set."
What the law says
In Florida, sexual battery and lewd or lascivious conduct involving minors are felony crimes that carry serious prison time. The state's sexual-battery provisions appear in Chapter 794 of the Florida Statutes, and both attempted sexual battery and burglary with assault or battery can result in lengthy sentences if a defendant is convicted, according to the Florida statutes.
Neighborhood safety and past incidents
The Park Towers complex has seen trouble before. It was the scene of a deadly shooting in 2025, as reported by the Miami Herald, a history that has left some residents on edge about safety in and around the building. Anyone with information about the current case is asked to contact the Miami-Dade Sheriff's Office; the county's contact page lists non-emergency reporting details and district office locations.
