Missouri woman federally indicted over threats against Austin Metcalf's family: 'I'll kill you next'

A woman from Missouri has been hit with a federal indictment in Texas for allegedly threatening the family of Austin Metcalf after Karmelo Anthony was convicted of the teen’s murder.

Sharifa Nicole Henderson, 34, was arrested by police on September 11 after a grand jury in the Eastern District of Texas had charged her with three counts of interstate threatening communications. Anthony's conviction was served on June 9.

According to the indictment, she used Facebook Messenger on June 10 to tell a Metcalf relative she would kill them and put them in a body bag, adding, "now this is a threat take me to court [expletive]." That same day, she phoned the Collin County government, whose office prosecuted Anthony, and reportedly vowed to "demolish" the Metcalf family and to "strangle" someone in the family, per Fox News.

The indictment quotes her as writing, "Don't worry I'll kill you next. I will hunt you forever until I kill you...I will be there. You will always have to look over your [expletive] shoulder."

Each count carries a maximum sentence of five years if she is found guilty in court. Austin's father, Jeff Metcalf, recently told FOX 4 that the family has gotten over 100 threats since the conclusion of the trial.

Anthony, 19, was found guilty more than a year after he fatally stabbed 17-year-old Metcalf at a regional high school track meet held at Kuykendall Stadium in Frisco, Texas, on April 2, 2025.

Investigators say Anthony, then enrolled at Centennial High School, walked to the Memorial High School team's tent and took a seat beneath it. Metcalf, who attended Memorial High, told him to leave the tent. After a verbal altercation, Anthony stabbed

A Collin County jury handed Anthony a 35-year prison term at his sentencing, and Anthony has tried to appeal, with lawyers claiming that because there were no black jurors that he was slighted by the justice system. Last month, a judge rejected his request for a new trial, though the family is preparing to appeal again.
