Texas teen convicted of murder for stabbing another athlete at a high school track meet

A Texas teenager was convicted of murder for fatally stabbing a rival high school athlete during a confrontation at a track meet; the jury rejected his self‑defense claim.
The incident began as a dispute over a team tent in the bleachers between students from different Frisco schools; the defendant, now 19, faces up to life in prison at sentencing.
The case drew wide attention on social media and stirred community emotion, though lawyers said race was not the motive; many people gathered outside the courthouse for the verdict.
