NASSAU COUNTY, FLORIDA — A single punctuation mark, a mere period, is all it takes for a predator to infiltrate your child’s digital environment. Experts warn that this small slip can allow someone to impersonate your child, reach out to their friends, and initiate grooming.

First Coast News offers an inside look at undercover operations designed to unearth the methods predators use and how quickly they act. For the first time, our reporter was granted access to a sting operation conducted by the Nassau County Sheriff’s Office.

Sheriff Bill Leeper is determined to make this information public, highlighting the urgency as these individuals actively seek to exploit children.

“You’re engaging in disturbing behavior. You’re despicable. You don’t belong in society,” Sheriff Leeper declared.

Flagler County detectives recently arrested Brandon Rodriguez-Silva, 20, of California, for allegedly soliciting a child in Palm Coast for unlawful sexual conduct.

According to the charging affidavit, a Palm Coast father discovered a “sexually explicit conversation with an unknown male” on his child’s iPad. Investigators say the two first connected on the online gaming platform Roblox.

Here’s how fast the grooming progressed:

• April 25: During their initial online contact, the man tells the child he bets they are pretty.

• May 6:  During a chat from the victim about “slime, school, and practicing … violin,” the man tells the child, “imma be giving you that princess treatment.”

• May 12: The man starts introducing sexual language, prompting the victim to say they feel “uncomfortable.”

• May 16: The man pressures the child, saying, “I’m ur bf u have to do what I tell u.”

Following this, he allegedly convinced the child to send barely clothed pictures of them in “various sexual positions,” and sent his own sexually explicit photo.

All of the messages occurred within just one month.

The messages were eventually discovered by the child’s father and reported to the sheriff’s office.

“I think this father did an outstanding job, being a sheriff in his own home,” said Flagler County Sheriff Rick Staly. “He probably saved his daughter from being sexually assaulted physically.”

Sheriff Staly says all parents “need to know just how dangerous keyboard warriors and perverts can be on the internet.”

The suspect lived across the country, but Staly says that doesn’t make the situation less dangerous. First Coast News asked if a child predator would really travel from California to Florida to have sex with a child he met online. 

“Well, we’ve seen it done.”

During Nassau County sting operation, First Coast News met Jamie Davis, an intelligence analyst with Internet Crimes Against Children (ICAC). She works out of the St. Johns County Sheriff’s Office and has handled almost 400 cases.  Davis says one trick can give a predator access to a whole community of children.

“Let’s say your child’s Instagram handle is “Smart_Blonde16″ and it’s not private,” Davis said. 

She explained that predators may create a fake account with the same username, but with an additional character like a period, so that it can easily be mistaken for the real one.

In this instance, “Smart_Blonde16.”

It’s so small you won’t even notice it, and then they go back to your child’s Instagram and start downloading photos,” Davis said. “Then they go to your child’s followers and start friend requesting them”

If someone asks why the new account popped up, they can make easy excuses like “I got hacked,” or “I got locked out.”

From there, predators may request video chats, with the children having no idea they’re talking to a stranger.

“What our teens are doing is getting on chat not paying attention. At first, maybe changing clothes or just getting out of the pool wearing a bikini or showing off new clothes that are revealing,” said Davis. “They are thinking they’re talking to friends, but they’re not. They’re talking to the bad actors.”

That one period becomes the doorway.

Davis urges parents to stay involved by checking their phones and chats. She also warns teens to avoid posting photos that attract predators, such as a pose that shows cleavage. She encourages them to edit pictures, place stickers over it, or move the camera up.

Davis also warns that predators will pose as new students at school, hoping kids will agree to meet them.

As both an investigator and a mother, Davis is firm. “There’s not a child in this world who needs social media before the age of 16.”, she says.

Her final plea to parents is to “be the parent who says no.”

Davis and other experts make a final warning to children, “A stranger is a stranger. He is not your friend.”
