The homeless man accused of fatally stabbing 23-year-old Iryna Zarutska on a light-rail train in North Carolina has been found unfit to stand trial at the state level. However, federal prosecutors have assured that this decision will not interfere with their own legal proceedings against him.

Decarlos Brown Jr., aged 34, faces charges for allegedly stabbing Zarutska to death on the Lynx Blue Line train in Charlotte on August 22, 2025.

Recent court documents, accessed by Fox News, reveal that Brown’s attorney disclosed an evaluation from Central Regional Hospital. This assessment concluded that Brown is “incapable to proceed” with his state criminal trial, thereby pausing the prosecution.

Nonetheless, officials from the Department of Justice have clarified that this determination is “completely separate” from the federal case against Brown, as stated by the U.S. Attorney for the Western District of North Carolina.

A booking photo of Decarlos Dejuan Brown Jr., taken on September 14, 2022, after his arrest in Mecklenburg County, shows the 34-year-old who is accused in the August 22, 2025, stabbing death of Ukrainian refugee Iryna Zarutska on a Charlotte light-rail train.

“I had a productive call this morning with our U.S. Attorney in Charlotte,” shared Harmeet Dhillon, Assistant Attorney General for the Civil Rights Division, in a post on X.

“Brown remains in federal custody and so the parallel state proceedings are in no way dispositive.”

A separate competency determination will be conducted in relation to the federal case against Brown, who remains in federal custody, according to Dhillon.

In lieu of the delay in Brown’s state proceedings, officials must conduct a separate psychiatric evaluation to determine if he is competent to stand trial – a process that cannot be initiated while he is in federal custody, according to court documents.

Approximately four minutes later, Brown allegedly pulled a knife from his pocket and stabbed her three times before walking off the train.

He was taken into custody moments later on the light-rail platform, while Zarutska was pronounced dead at the scene. 

Brown, a parolee with multiple documented run-ins with the law, has a long reported history of mental illness, according to family members.

By March 2024, authorities had logged six prior encounters with Brown, including multiple welfare checks triggered by his repeated 911 calls, according to The New York Times.

Just a year later, Brown called 911 from Novant Presbyterian Hospital, saying he needed help removing a “man-made” material he claimed was controlling him, the Charlotte Observer reported.

When officers arrived on scene, they reportedly told him they were unable to help. 

In a jailhouse phone call to his sister just days after Zarutska’s alleged killing, Brown made similar claims regarding “man-made” material controlling his mind.

Brown said he did not understand why he stabbed the 23-year-old refugee and claimed the government had implanted “materials” in his brain that were controlling his actions, in the call obtained by the Daily Mail.

“They just lashed out on her, that’s what happened,” Brown said. “Whoever was working the materials they lashed out on her. That’s all there is to it. Now they really gotta investigate what my body was exposed to… Now they gotta do an investigation as to who was the motive behind what happened.”

Brown remains in federal custody while he awaits trial on both state and federal charges. 

The DOJ did not immediately respond to Fox News Digital’s request for comment.
