Purported Deepfake Video Reportedly Misrepresented CBS Anchor Doug Dunbar and Frisco, Texas, Stabbing Suspect Amid Online Misinformation Campaign

May 8, 2025

A tragic high school stabbing incident in Frisco, Texas was followed by the alleged circulation of a deepfake video on Instagram. The purportedly manipulated content is said to have falsified CBS anchor Doug Dunbar's speech and portrayed suspect Karmelo Anthony holding a knife. This deceptive content, reposted across various accounts, has reportedly fuelled misinformation about the case and inflammatory online discussions.
