Detectives in Indian River County say they expect to find more victims of a man who created a fake Facebook persona to meet underage girls for sex.
Right now, the number of known victims is two, a now 14-year-old and a 12-year-old.
"Studies show that 100 percent of children who are on chat groups are at least once in their childhood approached by a predator," says Detective Jeremy Shepherd with the Indian River County Sheriff's Office.
Detective Shepherd says two weeks ago, he was contacted by the wife of a church youth pastor concerned over what some young girls had told her; that one of their friends had been hanging out with a man named Jonathan Langley, who they first connected with online.
"He (Langley) ended up "friending" a number of young teenage females and in turn was able to friend all of their friends," said Det. Shepherd.
But in reality, it wasn't Jonathan Langley. Detectives say it was really 25-year-old Jay Nagel.
According to an arrest affidavit, Nagel, who worked at a mattress store on State Road 60, brought one girl he first met online to the store after hours, where he had sex with her.
Shepherd says based on his interviews with Nagel, he expects to find more victims.
Shepherd says parents need to keep the lines of communication open with their kids and be aware of their children's online behavior.
He suggests monitoring software. "They can do anything from just blocking your children from certain sites or from using certain apps to actually sending to your cell phone everything your child is doing on their cell phone or computer."
Nagel is being held on a $150,000 bond.
If you have any information in this case, you're asked to contact Detective Shepherd at (772) 978-6120 or Treasure Coast Crime Stoppers at 1-800-273-8477.
