A federal grand jury in Charlotte has handed down multiple sex charges against a Boone man.
The charges are the result of a probe by Immigration and Customs Enforcement's Homeland Security Investigations and the Boone Police Department.
Frank Darrell Cromwell, 23, of Boone is charged with 21 crimes including production of child pornography, enticing a minor, and cyberstalking.
Prosecutors allege that Cromwell used a cell phone app and other means to entice minor male victims to produce sexually explicit images and videos. Court documents include allegations that Cromwell misled the victims by posing as a female online.
Law enforcement officers have identified ten victims, according to a release from the United States Attorney's Office for the Western District of North Carolina.
Cromwell was serving as an athletic trainer at Watauga High School through an internship from Appalachian State University. Prosecutors allege he met some of his victims through that internship.
The charges are allegations and have not been proven in court.
