A former Orlando middle school music teacher has pleaded guilty to federal charges after investigators say he coerced over 20 children online. Prosecutors say 25-year-old Italo Rafael Brett Bonini offered incentives to an 8-year-old boy in exchange for sex acts. Bonini admitted to targeting kids for control and manipulation. He now faces at least 15 years in prison, possibly life. Sentencing is set for July 30.
