In the murder trial of Karmelo Anthony, a witness told jurors Monday that Anthony was upset immediately after the fatal stabbing of 17‑year‑old Austin Metcalf at a school stadium in Frisco in April 2025. Anthony, now 19, is charged with murder in Metcalf’s death.
The witness testified that, before the confrontation, he warned the victim "not to touch me," and that Anthony appeared distraught after the encounter. The testimony came as the trial entered its second week and added an on‑the‑ground account to competing accounts of the confrontation at the rainy track meet.
Prosecutors say the killing was an unprovoked attack stemming from a dispute over whether Anthony could be under the tent used by Metcalf’s team during the rain. Defense attorneys counter that Anthony felt threatened. The new witness testimony offers evidence that defendants and prosecutors will frame differently as they argue motive and state of mind to the jury.
The central, numerical facts are short: the stabbing occurred in April 2025 at a school stadium in Frisco, a suburb of Dallas; the victim, Austin Metcalf, was 17; the defendant, Karmelo Anthony, is 19 and faces a murder charge.
During Monday’s testimony the witness described warning the other teenager with the precise words "not to touch me." The witness also said Anthony was upset immediately after the confrontation; the remark about being upset is the clearest emotion on the record so far and is likely to be weighed against other testimony about what happened under the tent at the meet.
The prosecutorial theory rests on the claim that the attack was unprovoked and connected to the tent dispute at the rainy track meet. The defense theory rests on an assertion that Anthony felt threatened at the scene. The difference between those two positions — whether there was an unprovoked assault or a perceived threat — is the hinge of the case and the lens jurors will use to assess the witness’s description of Anthony’s behavior after the stabbing.
What remains unanswered is the exact sequence of events inside the tent at the Frisco meet. Witness testimony like Monday’s fills in immediate reactions but does not, by itself, resolve the core question: what triggered the fatal stab. The trial will continue to present more testimony and evidence, and jurors must decide whether the testimony that Anthony was upset supports a finding of criminal intent or of fear and self‑defense.
