911 call captures chaos after Austin Metcalf stabbing
Anthony was found guilty last week in the deadly stabbing of Frisco teenager Austin Metcalf at a high school track meet and received a 35-year prison sentence. Newly unsealed exhibits now offer the public a more detailed view of the evidence jurors reviewed before delivering their verdict.
Hours before Karmelo Anthony fatally stabbed Austin Metcalf during a Texas high school track meet on April 2, 2025, Anthony’s girlfriend had alerted school staff that he was allegedly stalking her while sending texts saying he was “on the verge,” according to a 75-page court document obtained by News Outlet.
Earlier that morning, Valeria Torres Perez, Anthony’s girlfriend, told a staff member at Centennial High School that Anthony had been driving past her home and would not accept her attempts to end their relationship.
Text messages attributed to Anthony show that at 12:59 a.m., he wrote, “im lowk on the verge.” The message did not explain what he meant. Roughly 35 minutes later, he repeated the phrase and placed added emphasis on it.

The filing details dozens of alleged prior acts that prosecutors sought to present at trial, including threats, assaults, weapons-related messages and comments about committing robberies. The document does not state that those messages involved Metcalf, nor does it establish that any weapon discussed in the exchanges was used in the stabbing at the track meet.
Prosecutors submitted the notice on May 8, 2026, identifying extraneous offenses they planned to use during the trial. The filing is not a court determination that the alleged acts happened, and it cautions that some screenshots show only parts of longer conversations.
The notice also points to an exchange with Perez dated Dec. 23, 2023, in which Anthony described losing control when he became 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 that same exchange, Anthony allegedly said he assaulted another person after the individual posted about “smoking” Anthony’s cousin. “He posted where he was at and we pulled up and got em,” Anthony wrote.
A May 5, 2024, Instagram photo allegedly showed Anthony holding a firearm while posing with a group.
By May 17, 2024, Anthony had told Perez he was going to shoot a woman, writing, “im shooting her,” the notice says. On June 10, 2024, he allegedly threatened to shoot Perez by asking, “how many bullets uu want coming out of ur chest.”
Six days later, he allegedly threatened to assault Perez again, writing, “imma beat ur a–.”
The threats continued into the fall of 2024. During September, Anthony allegedly made threats involving a gun, writing “gun to the head” and saying he would cut another person’s brakes. By November, he had allegedly written about shooting something up and referred to gloves, a rope and getting his hands on a switch.
The notice says a Nov. 13, 2024, video showed Anthony holding what appears to be a firearm.

A Jan. 4, 2025, video allegedly showed Anthony aiming what appears 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 with Anthony Mendoza. A Feb. 26, 2025, exchange involving a different phone number included a discussion about carrying a firearm.
The notice also says Anthony discussed committing robberies in January 2025 and was suspended for fighting in February 2025.
By March 2025, the messages directed at Perez had grown more threatening. Anthony allegedly texted her on March 8, 2025, “imma f—— murder u … yo friends go die … sho them ts.”

The document also cites alleged racist and anti-gay messages, discussions about narcotics, photographs and videos involving firearms, and statements about fighting and assaulting other people. It traces alleged misconduct back to Anthony’s school years in Baton Rouge, Louisiana, including “numerous acts of assaultive conduct.”
Anthony was convicted of killing Metcalf and sentenced to 35 years in prison. He has appealed the conviction.
The court document does not provide a formal mental-health diagnosis or establish that Anthony was experiencing a psychiatric crisis before the shooting. Instead, it presents prosecutors’ account of prior conduct they argued could be relevant to the case.
News Outlet reached out to Anthony’s attorney, Russell Wilson, for comment.
