A group representing the family of a 17-year-old accused of fatally stabbing Texas track athlete Austin Metcalf said authorities moved him to an undisclosed location for safety reasons.

The Next Generation Action Network said in a statement that Karmelo Anthony left his home after the family received death threats, ongoing harassment, and physical intimidation. The group cited what it called an “alarming increase” in targeted threats as the reason for the move.

The nonprofit reported that threats against Anthony’s family have intensified, including death threats, harassment, and physical intimidation at their residence, FOX News Digital reports.

As CrimeOnline previously reported, prosecutors charged Anthony with first-degree murder in the April 2 stabbing of Austin Metcalf, also 17. The incident happened at the Kuykendall Stadium in Frisco during a multi-school track and field championship, over a seating dispute.

Police said Anthony and Metcalf didn’t know each before the altercation, which ended when Anthony stabbed him in the chest and fled. Police arrested him shortly after.

The arrest report said Anthony told a school officer that Metcalf “put his hands” on him. When the officer referred to him as the suspect, Anthony said, “I’m not alleged. I did it.”

People have  reportedly shown up at the family’s residence, taken photos, and posed as fast food delivery drivers. The family has also received unsettling items in the mail, including an obituary for Austin Metcalf. Some people have allegedly tried to frighten the family further.

Dominique Alexander, a minister with NGAN, said the group released photos and records of recent threats to highlight what he called a dangerous climate driven by hate groups, racism, and misinformation.

“It is both heartbreaking and infuriating to see the depths of hate and bigotry still alive and well in our society. No family should have to live under siege simply because they are demanding their constitutional rights. We will not be silent, and we will not back down. We are committed to doing whatever is necessary to protect this family and to ensure that justice is pursued without intimidation or fear.”

Last week, Anthony’s family held a press conference to address threats and public backlash. Kala Hayes, Anthony’s mother, said someone posted their home address online. She said her husband took a leave of absence out of concern for the family’s safety.

Hayes also said her 13-year-old daughter no longer feels safe sleeping in her own room.

Austin Metcalf’s father, Jeff Metcalf, appeared at the press conference but left after police asked him to exit before it began. He told CBS News Texas he had hoped to connect with Anthony’s family.

Meanwhile, Anthony remains free on bond, pending trial. Check back for updates.
