A Texas murder conviction sent shockwaves rolling far beyond the Lone Star State this week, igniting a social media firestorm and a disturbing act of street violence hundreds of miles from the courthouse where justice was served.
Karmelo Anthony, now 19, learned his fate Tuesday when a jury handed down a guilty verdict followed swiftly by a 35-year prison sentence — punishment for the 2025 stabbing murder of Austin Metcalf at a Frisco, Texas high school track meet.
The confrontation that ended Metcalf’s life began with a provocation. Anthony walked uninvited into the tent occupied by Metcalf’s team and issued an open challenge for anyone present to physically remove him.
When Metcalf moved to do exactly that, Anthony drew a knife. He would later claim the killing was an act of self-defense.
That claim found little support among those who witnessed the encounter firsthand. Trial testimony was overwhelmingly consistent in placing Anthony as the one who escalated the situation into lethal territory.
The case carried a charged racial dimension from the start — Anthony is Black, Metcalf was white — and that dimension ensured that emotions ran high long before the jury ever returned its verdict.
Outside the Collin County Courthouse in McKinney, supporters of Anthony clashed with demonstrators and hurled racial slurs, providing an early preview of the ugliness that would follow the conviction announcement.
What unfolded in Florida, however, took things to an entirely different level.
A content creator operating under the name “Combak KidBoe” posted video footage to social media that purportedly showed him walking up to a white military veteran and punching him square in the face — unprovoked, in broad daylight.
The caption KidBoe attached to the footage left little ambiguity about his motivation: “um down to 4 crackers na free karmelo.”
Before throwing the first punch, KidBoe turned to the veteran and asked pointedly, “Weren’t you on jury selection?” The man was then told he was going to die.
KidBoe’s social media profile places him in Jacksonville, Florida, with roots in Miami Beach — a significant geographic distance from the McKinney, Texas courtroom where the Anthony trial was conducted.
Whether the veteran targeted in the video had any actual connection to the Anthony jury remains unverified. Whether Florida law enforcement has opened any investigation into the attack is equally unclear.
The video was pulled from Facebook, where KidBoe commands a following of more than 5,800 users. Undeterred, he turned around and reposted the footage to Instagram Wednesday morning, reaching a much smaller audience of 261 followers on that platform.
Rather than distance himself from the content after its removal, KidBoe publicly confirmed the takedown while simultaneously continuing to post pro-Anthony material across his accounts.
The veteran’s identity has not been publicly confirmed, and the specific location of the assault within Florida has not been disclosed.
What is confirmed is that a guilty verdict in a Texas courtroom produced real-world violence against a private citizen in another state entirely — carried out on camera and uploaded for public consumption under a rallying cry for a convicted killer.
