A man who reportedly identified as a “Nazi” and said the joined the army to practice killing Black people, was arrested last month after he was discharged from the army for misconduct.

Killian Mackeith Ryan, who was stationed in North Carolina, was arrested Aug. 26, shortly after he was discharged from the army, according to a spokesperson. Federal prosecutors said an investigation revealed Ryan lied about his relationship with his father in his 2020 application for a security clearance, reported Rolling Stone.

“I serve for combat experience so I’m more proficient in killing (n-words),” reads a message sent by one of Ryan’s Instagram accounts, according to the criminal complaint, reported Rolling Stone.

A local police officer assigned to the FBI’s local Joint Terrorism Task Force wrote in an affidavit that via Instagram, Ryan “had been in contact with numerous accounts associated with racially motivated extremism,” reported Rolling Stone.

The criminal charges against Ryan are not connected to his messages online, but federal prosecutors added much of what they found in the investigation to their complaint.

Prosecutors alleged Ryan wrote in he had not seen his biological father in 10 years. However, authorities uncovered evidence that Ryan’s biological father attended his high school graduation. Officials said they also discovered Ryan had been communicating with his father through Instagram, reported Rolling Stone.

The complaint also said an Instagram account associated with Ryan’s biological father, was also in contact with multiple accounts associated with racially-motivated extremism, reported Rolling Stone.
