The FBI is now helping in the investigation of a Texas teen accused of fatally stabbing another teen during a track meet in Frisco.
Karmelo Anthony, who is 17 years old, has been accused of stabbing another 17-year-old, Austin Metcalf, in the heart on April 2 at Kuykendall Stadium, which is part of the Frisco Independent School District. This unfortunate incident took place while both teens were attending a track and field meet.
According to a probable cause affidavit obtained by CrimeOnline, witnesses reported that the confrontation began when Metcalf asked Anthony to vacate a tent that had been set up for Metcalf’s track team.
The affidavit stated that the two had never met before the incident.
After the tragic event, a false account posing as Frisco Police Chief David Shilson emerged on April 3, just a day following the stabbing, as disclosed by the police department on X. Subsequently, on April 4, Shilson issued a statement advising the public to disregard any inaccurate information and solely rely on official announcements and verified sources.
“Beware of those taking to social media to deliberately spread misinformation, hate, fear and division,”Frisco Police Chief David A. Shilson posted on X., stating someone called the incident a “mutual combat altercation” after Metcalf “sucker punched” Anthony.
A police report, however, stated that Metcalf grabbed Anthony, who was allegedly sitting under a tent designated for Memorial High School students.
Metcalf was a junior football star at Memorial, while Anthony attended Centennial High School. The affidavit stated that Anthony reached into his bag upon being told he was sitting in the wrong area.
A witness reported hearing him say, “Touch me and see what happens.”
The chief added that the same fraudulent account claimed Metcalf also smashed Anthony’s phone “onto one of the bleachers.”

“Regarding the Frisco PD Chief imposter post seen on Thursday/Friday last week, I can confirm that we are assisting Frisco PD, but that any further investigative updates will come from Frisco,” an FBI spokesperson confirmed to NewsNation.
One fake image mentioned in the warning surfaced in the comments under official social media posts. It appeared to show an autopsy report claiming Metcalf’s primary cause of death was an MDMA drug overdose, with stab wound-related blood loss listed second.
Metcalf’s cause of death has not yet been released.
“The Frisco Police Department is aware of an image circulating on social media purporting to be a report from the Collin County Medical Examiner’s Office. At this time, the report has NOT been released. Therefore, any information currently found online is FALSE,” the police department said.
Following the stabbing, Anthony allegedly asked police if Metcalf was going to be OK and if the incident constituted self-defense.
“I know that my client said it was self-defense. I don’t have any reason to disbelieve that, but I need to develop facts, talk to people and figure out what’s going on before I make any statements about what I think happened,” Anthony’s defense lawyer, Deric Walpole, told NBC 5. “I don’t have any reason to think it wasn’t self-defense at this time.”
Meanwhile, ABC 8 reports that Anthony’s family has faced harassment and threats since the incident. Dominique Alexander, founder of the Next Generation Action Network, told the outlet that someone leaked the family’s address online, prompting a wave of graphic and racist threats.
“The disinformation that is going online is hurting this case, and it has to stop. As we know right now, Austin Metcalf and Karmelo Anthony did not know each other,” Alexander said. “Karmelo Anthony has a right to a fair trial, unbiased and removed of racial hate and bigotry.”
Anthony remains behind bars in the Collin County Jail on $1 million bail. Check back for updates.
