MMA fighter helps unmask Florida student leader in predator sting

An MMA fighter from 561 Predator Catchers confronted Christian Walden, a Florida Atlantic University student government leader, after a decoy online chat allegedly arranged a meeting with a 13-year-old. Walden was arrested at a Home Depot for planning sex with a minor and was impeached from FAU's student government; Lampros’ civilian sting videos are shared online as evidence. Florida allows citizen-led predator stings if not coordinating with police, but entrapment and evidentiary issues can complicate cases.
