Meet for sex
Dallow was sentenced to two years in prison at Winchester Crown Court after previously admitting attempting to meet a teenage girl with the intention of committing sexual assault against a child.
Officials say Garcia traveled from Milwaukee to Racine with the intent to meet with a 15-year-old girl for sex.
Deputies said on Thursday that Petko communicated with the investigators again and arranged to travel to Seminole County to meet the girl in exchange for an i Phone.
Petko was arrested on Thursday for traveling to meet a minor for sex and soliciting a parent to have sex with a minor. Copyright 2017 by WKMG Click Orlando - All rights reserved.
Sentencing, Judge Parker QC said Dallow was a "dangerous offender" after a report found him to be a high risk to girls aged twelve to sixteen.
He said: "[Emma] herself was not actually harmed, because she didn't exist.
The Houston-Metro Internet Crimes Against Children Task Force said 13 men have been arrested for attempting to have sex with children they met online.
