Karmelo Anthony was found guilty last week for the fatal stabbing of Frisco teenager Austin Metcalf. The incident occurred during a high school track meet, leading to a 35-year prison sentence. Recently, newly released exhibits provide insights into the evidence that impacted the jury’s decision.
Before the tragic event took place, Anthony’s girlfriend reported his alarming behavior to school authorities. On April 2, 2025, Valeria Torres Perez notified Centennial High School staff about Anthony’s actions, which included driving by her home persistently and disregarding her attempts to end their relationship. Earlier that day, Anthony sent text messages indicating his unstable state, which were documented in a 75-page court document acquired by Fox News Digital.
The court filings highlighted a concerning text exchange from December 23, 2023, in which Anthony articulated feelings of uncontrollable anger. In those texts, he described seeing red, blacking out, and having eyes change color when angry. This, along with multiple other alarming exchanges, formed a part of the prosecutors’ evidence.
A screenshot from a Texas court filing demonstrated how Anthony threatened others when provoked or angry. On May 5, 2024, another image depicted Anthony with a firearm, posing with peers, amplifying prosecutors’ claims of his dangerous conduct.
Throughout 2024, Anthony allegedly made numerous threats involving firearms and assaults towards Perez and others. The court notices referenced multiple exchanges, highlighting threats to shoot and statements surrounding violence toward Perez. For instance, in March 2025, his texts displayed alarming death threats towards Perez and her friends.
Records suggest Anthony discussed firearms acquisition in early 2025. On January 4, 2025, a video reportedly showed him aiming a firearm at a residence, further contributing to prosecutors’ arguments during the trial.
Anthony’s appeal against the conviction is marked within these ongoing developments. However, there’s no explicit evidence of any formal mental-health diagnosis, despite the critical nature of his prior alleged misconduct.
