A Missouri woman was federally indicted in Texas after allegedly threatening the family of Austin Metcalf following Karmelo Anthony’s conviction for the teenager’s killing.
Sharifa Nicole Henderson, 34, was arrested in Kansas City on Sept. 11, two days after a federal grand jury in the Eastern District of Texas indicted her on three counts of interstate threatening communications.
Anthony’s trial concluded on June 9, and prosecutors allege Henderson made three separate death threats against the Metcalf family in the days that followed.
On June 10, Henderson sent a message through Facebook Messenger to one of the Metcalf family members saying she would kill them and put them in a body bag before stating, “now this is a threat take me to court [expletive],” according to the indictment.

KARMELO ANTHONY SUPPORTER REPORTEDLY FIRED AS OTHER BACKERS FACE BACKLASH OVER VERDICT REMARKS
Again on June 10, Henderson called the Collin County government, which prosecuted the case against Anthony, and said she would “demolish” the Metcalf family and “strangle” one of them, per the indictment.
And on June 11, prosecutors say Henderson sent another threatening message on Facebook Messenger to a family member.
“Don’t worry I’ll kill you next,” she allegedly wrote, according to the indictment. “I will hunt you forever until I kill you…I will be there. You will always have to look over your [expletive] shoulder.”
If convicted, Henderson faces up to five years in prison for each charge.

AUSTIN METCALF’S FATHER ACCUSES MEDIA PUNDITS OF TRYING TO MONETIZE HIS SON’S DEATH ‘FOR CLICKS’
Jeff Metcalf, Metcalf’s father, recently told FOX 4 Dallas-Fort Worth that his family has received more than 100 threats since the end of the murder trial.
The case drew national attention and became racially charged, with supporters of Anthony criticizing the lack of Black jurors and calling for his acquittal, while supporters of the Metcalf family gathered outside the courthouse seeking justice.
Anthony, 19, was convicted more than a year after fatally stabbing Metcalf, 17, during a regional high school track meet at Kuykendall Stadium in Frisco, Texas, on April 2, 2025.
Anthony, then a Centennial High School student, made his way over to the Memorial High School team’s tent and sat under it, according to investigators.

Metcalf, a student at Memorial High, then allegedly told Anthony to leave. Prosecutors said Anthony provoked the confrontation that ended with Metcalf being fatally stabbed in the chest.
Surveillance footage later released showed Anthony running from the tent. In police reports obtained by Digital, Anthony was heard telling arresting officers: “I’m not alleged, I did it.”
Authorities would later say they found no evidence suggesting the two knew each other prior to the incident.
A Collin County jury sentenced Anthony to 35 years in prison. Last month, a judge denied Anthony’s motion for a new trial, though the family is readying another appeal.
