Dramatic 911 calls obtained by the New York Post provided more details on the murder of a Ukrainian refugee on a North Carolina train.

Iryna Zarutska, 23, was reportedly already unconscious and had lost tons of blood before bystanders got through to dispatch.

“A man just f**king stabbed this woman for no reason,” a passenger said during the 911 call.

“Please hurry, she’s bleeding. She’s bleeding a lot," the distressed caller said.

The eyewitness described the suspect, later identified as Decarlos Brown Jr., 34, as a Black man who had already exited the train at the time of the call. Another caller told dispatch that Zarutska was "not responsive" as bystanders attempted to apply pressure to her stab wounds in an effort to stem her bleeding.

“This lady just got stabbed. There is a lady on the ground with a lot of blood…we didn’t see it,” the woman said. “People are freaking out. There is a lot of blood. I think she’s gone.”

Brown's mother aid her schizophrenic son should have never been released from jail as his mental health was quickly deteriorating.

“He shouldn’t have been released,” said Michelle Dewitt in an exclusive interview with the New York Post outside her home on September 10, referencing him being free on a "written promise" to appear in court after being arrested in January.

Dewitt said she took her son to a homeless shelter days before the incident took place after he had grown increasingly aggressive to both her and her husband. The 51-year-old denied that the attack was racially motivated, claiming her son was "definitely not racist" and had "dated all kinds of girls."

“When you bring a person to mental health, and [they] tell you ‘we don’t have enough space’ or, ‘is he trying to kill himself or someone else?’ and I say no, then there is nothing we can do, you need to get a court order,” Dewitt said.

Disturbing audio from Brown's phone conversation with his sister, Tracey, who he previously assaulted during a biting incident in 2022, included him claiming that "the material in his body" was responsible for killing Zarutska, not himself, six days after the murder took place, the Daily Mail reports.

“I hurt my hand, stabbing her. I don’t even know the lady. I never said not one word to the lady at all. That’s scary, ain’t it. Why would somebody stab somebody for no reason?” Decarlos said on the audio.

“Out of all people, why her? She’s from the Ukraine, she’s from Russia, and they had a war going on against the United States, so I’m just trying to understand, of all people, why her?” Tracey asked.

“They just lashed out on her, that’s what happened. 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," Decarlos responded.

Tracey also confirmed that her brother is a paranoid schizophrenic who had claimed that the government had implanted a chip in him multiple times prior to the fatal incident on a Charlotte, North Carolina, train.

“A person that is hearing voices in their head and believes the world is against them, they’re going to break. And I think that night he broke,” Tracey told CNN.

President Donald Trump shared a post calling for Brown to face the death penalty on his Truth Social account on September 10.

"The ANIMAL who so violently killed the beautiful young lady from Ukraine, who came to America searching for peace and safety, should be given a “Quick” (there is no doubt!) Trial, and only awarded THE DEATH PENALTY. There can be no other option!!!" Trump wrote.

Brown was charged with a federal count of committing an act causing death on a mass transportation system Tuesday (September 9), having already faced a first-degree murder charge. Attorney General Pam Bondi publicly stated her intention to "seek the maximum penalty for this unforgivable crime" and vowed that Brown would "never again see the light of day as a free man.”

Brown was freed after a magistrate released him with just a "written promise" to appear in court, despite having been arrested at least 14 times in North Carolina since 2007. The suspect's mother told WSOC that her son, who is homeless, was schizophrenic and shouldn't have ever been freed prior to stabbing Zarutska to death.

Surveillance video shows a man identified as Brown pulling out a pocket knife and stabbing Zarutska in the neck. Brown is currently being held in Mecklenburg County Jail without bond.
