Federal prosecutors announced Friday that a Kansas woman has been indicted on three counts stemming from threatening Facebook Messenger messages allegedly sent to Jeff Metcalf, the father of slain Frisco teenager Austin Metcalf. According to the indictment, Sharifa Nicole Henderson told Metcalf she would put him in a body bag, vowed to demolish his family, and warned that she would hunt you forever until I kill you.
The charges were announced at the U.S. Attorney's Office in Plano, Texas, and mark the latest criminal case stemming from threats and violent rhetoric surrounding the Anthony trial, according to CBS News. Austin Metcalf, 17, was fatally stabbed at a Frisco high school track meet, a case that led to the murder trial of Karmelo Anthony, who was 19 at the time of his conviction. The messages to Jeff Metcalf were allegedly sent in June 2026, around the time Anthony's trial reached its conclusion.
What the Indictment Says Henderson Wrote
The indictment lays out a string of alleged messages that prosecutors say Henderson sent directly to Jeff Metcalf. Among them: don't worry i'll kill you next, and now this is a threat take me to court [expletive]. She also allegedly told him he would always have to look over his shoulder, and that she would strangle a family member.
Henderson has made an initial court appearance in the case. She faces up to five years in prison and a fine of up to $250,000 if convicted, penalties consistent with the federal statute governing threats transmitted across state lines. Under 18 U.S.C. § 875(c), transmitting a threat in interstate commerce to injure another person carries that same maximum statutory penalty per count, according to the Law Offices of Sean Buckley, PLLC, which notes federal jurisdiction applies here because the messages crossed state lines between Kansas and Texas.
A Trial That Drew Threats From Both Directions
The federal case against Henderson centers on alleged threats against Jeff Metcalf, but he was not the only figure in the case to draw threats during the trial. Collin County authorities had previously charged far-right activist Edward Jacob “Jake” Lang with felony terroristic threats after he livestreamed a vow to deliver a headshot to Anthony outside the courthouse, according to CBS News. Lang had also been arrested in Frisco earlier that month on a criminal trespassing warrant tied to entering David Kuykendall Stadium, the site of Metcalf's death, according to Law & Crime.
A Collin County judge later reduced Lang's bond to $250,000 and ordered him to leave the state of Texas within 24 hours pending trial, barring his return except for court dates — an unusual bond condition that legal observers noted is exceptionally rare in Texas. Lang's history of provocative conduct continued beyond the Collin County case; Hoodline has previously reported on his broader pattern of demonstrations drawing law enforcement attention.
The Underlying Murder Case
Anthony was convicted of murder by a Collin County jury in June 2026 for the April 2, 2025 fatal stabbing of Metcalf at the track meet, and was sentenced to 35 years in prison. A Texas visiting judge later denied Anthony's motion for a new trial on August 22, 2026, rejecting defense claims that prosecutors had violated an informal agreement over character evidence, according to The Guardian. Under Texas law, individuals convicted of murder must serve at least half their sentence before becoming eligible for parole, meaning Anthony would need to serve a minimum of 17.5 years before consideration.
The case drew national attention throughout the trial, with viral online posts fixating on the racial identities of the Black defendant and white victim. During the trial, the Texas Department of Public Safety and the Texas Fusion Center actively monitored social media channels and courthouse grounds to track violence and threats tied to the proceedings.
Ripple Effects Across North Texas
The fallout from the case has reshaped how the region handles both public events and online rhetoric. Following Metcalf's death, Frisco ISD and regional athletic organizers overhauled postseason track meet operations, introducing metal detectors, bag checks, and increased law enforcement patrols at Little Elm's Lobo Stadium, as Hoodline detailed in its report on the track meet's tense return. Track meets have traditionally operated as open facilities with scattered team tents, which complicated efforts to control access.
Together, the Henderson indictment and the earlier charges against Lang show that violent rhetoric surrounding the trial targeted figures on both sides of the courtroom — the defendant and the victim's family alike — prompting law enforcement responses across multiple jurisdictions and now across state lines.
