The texter in the Netflix documentary "Unknown Number: The High School Catfish" was Kendra Licari, the mother of Lauryn Licari, a teenage girl who was harassed alongside her then-boyfriend Owen McKenny by anonymous, harassing text messages for over a year. The investigation, which involved local police and the FBI, traced the texts back to Kendra Licari, who sent the messages using an app that disguised her phone number. Kendra eventually confessed to the harassment and claimed she started sending texts to uncover the original perpetrator but then continued the campaign herself. She pleaded guilty to stalking and served time in prison for her actions.
