Federal and local authorities are investigating the shooting death of Ramzan Daraev, a 35-year-old Chechen man who was near the rural North Carolina home of a U.S. Army Special Operations Command colonel on May 3 and allegedly photographed the colonel’s children and was shot multiple times after becoming “aggressive” when approached.

According to the Moore County Sheriff’s Office, Daraev and another Chechen man were posing as utility workers for Utilities One, a New Jersey-based company, but lacked proper equipment, clothing, and identification. The second man was detained, questioned, and released.

The incident has raised concerns among Special Ops soldiers nationwide, who report increased surveillance of their families. The shooting also coincides with the arrest of two illegal immigrants from Jordan attempting to force their way onto Quantico Base in Virginia on the same day.

The colonel, whose name and rank have not been disclosed, had reportedly set up cameras on his property and had seen the men several times before the shooting. The 911 call came in at 8:15 p.m., an unusual time for utility work.

Utilities One CEO Serghei Busmachiu released a statement expressing sadness over Daraev’s death and reminding people about the company’s diverse workforce. Daraev’s family has created a Change.org petition calling for justice, claiming he was unarmed and shot in the back and face while running away.
