FRISCO, TEXAS: Karmelo Anthony, the 17-year-old charged with the fatal stabbing of fellow student Austin Metcalf, has been relocated to an undisclosed location after reportedly receiving multiple death threats while under house arrest.

Anthony’s family, in a statement released over the weekend, expressed “grave concern” over what they described as an “alarming rise” in harassment and threats. According to Fox4, individuals have been seen loitering outside the family’s residence, sending Metcalf’s obituary in the mail, and even attempting to intimidate the family through false food deliveries.

Since his release on a $250,000 bond—down from an initial $1 million—Anthony had been staying at a home in Frisco, purchased with funds raised for his legal defense.

Anthony is facing a murder charge in connection with the April 2 fatal stabbing of Austin Metcalf during a high school track meet. Both teens were 17 at the time of the incident.

The move to a secure location was also prompted by a recent rally in Frisco, organized in response to the case. The rally, promoted online with slogans such as “Protect White Americans,” “Justice for Austin Metcalf,” and “Stop Black Violence on White Americans,” drew sharp criticism for its racial overtones. The event, billed as a “peaceful protest,” took place Saturday morning in the parking lot of Kuykendall Stadium. Frisco Police reported two arrests during the demonstration.

The Anthony family is now receiving assistance from the Next Generation Action Network (NGAN), a Texas-based civil and human rights organization, to help navigate the escalating situation.
