Karmelo Anthony was convicted last week in the fatal stabbing of Frisco teenager Austin Metcalf and sentenced to 35 years in prison. The conviction followed a trial where evidence, now made public through newly released court documents, shed light on alleged prior acts of violence, threats, and a fixation on weapons.

Hours before the April 2, 2025, stabbing at a Texas high school track meet, Anthony's girlfriend reported him to school staff for alleged stalking. Text messages attributed to Anthony from early that morning show him writing, "im lowk on the verge," a statement he repeated approximately 35 minutes later. His girlfriend, Valeria Torres Perez, had told a Centennial High School staff member that Anthony had been driving by her home and refusing to allow her to end their relationship.

The 75-page court document obtained by Fox News Digital outlines dozens of alleged prior acts prosecutors sought to introduce at trial. These included threats, assaults, and messages related to weapons. The document does not specify if the weapon messages pertained to Metcalf or confirm if any weapon mentioned was used in the stabbing.

Prosecutors filed a notice on May 8, 2026, to identify these extraneous offenses, which is not a judicial finding that the alleged acts occurred. The notice also warns that some screenshots may only capture portions of full exchanges.

Evidence cited in the notice reaches back to December 23, 2023, when Anthony allegedly described losing control when angry. "When I get mad i see red," he wrote. "When I get mad i blackout," "When I get mad i cant control myself" and "When I get mad my eyes change color." In the same exchange, he allegedly recounted assaulting another person after that individual posted about him. "He posted where he was at and we pulled up and got em," Anthony reportedly wrote.

A May 5, 2024, Instagram photo allegedly showed Anthony holding a firearm while posing with a group. By May 17, 2024, Anthony had texted Perez, "im shooting her," according to the notice. On June 10, 2024, he allegedly threatened Perez by asking, "how many bullets uu want coming out of ur chest." Six days later, he allegedly threatened to assault her again, writing, "imma beat ur a–."

Threats continued into the fall of 2024. During September, Anthony allegedly made threats involving a gun, writing "gun to the head" and stating he would cut another person's brakes. By November, he had allegedly written about shooting something up and referenced gloves, a rope, and obtaining a switch. A Nov. 13, 2024, video cited in the notice reportedly showed Anthony holding what appeared to be a firearm.

A Jan. 4, 2025, video allegedly showed Anthony aiming what appeared to be a firearm at a home before running away. Separate exchanges with other contacts followed. On Feb. 19, 2025, Anthony discussed buying a firearm and an extended clip in a text conversation. A Feb. 26, 2025, exchange involving a different phone number included a discussion about carrying a firearm.

The notice also states Anthony discussed committing robberies in January 2025 and was suspended for fighting in February 2025. By March 2025, messages directed at Perez became more threatening. Anthony allegedly texted her on March 8, 2025, "imma f-----g murder u … yo friends go die … sho them ts." The notice says Anthony assaulted Perez on March 14, 2025. Thirteen days later, he allegedly threatened her with a deadly weapon and referenced having a gun.

The document also cites alleged racist and anti-gay messages, discussions about narcotics, and statements about fighting and assaulting others. It traces alleged misconduct back to Anthony’s school years in Baton Rouge, Louisiana, including "numerous acts of assaultive conduct."

The court document does not provide a formal mental-health diagnosis or establish that Anthony was experiencing a psychiatric crisis before the shooting. It presents prosecutors’ account of prior conduct they argued could be relevant to the case. Anthony has appealed his conviction.
