The mother of a suspect who allegedly killed a Ukrainian refugee on a North Carolina train claims her son is not racist because he ‘dated all kinds of girls.’

DeCarlos Brown Jr., 34, allegedly said ‘got that white girl’ after stabbing 23-year-old Iryna Zarutska on a train in Charlotte on August 22.

But his mother, Michelle Dewitt, told the New York Post the attack couldn’t have been racially motivated and that her career criminal son was ‘definitely not racist’ because he ‘dated all kinds of girls.’

She also said she had taken Brown to a homeless shelter just days before he would fatally stab Zarutska, and that he had grown aggressive toward her and her husband.

‘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,’ she told The Post.

Brown was reportedly resistant to seeking help, despite his mom’s pleas.

Dewitt, 51, also agreed her son should not have been released from jail, especially on a ‘written promise’ that he would show up to his court date after his arrest in January for misusing 911.

She does, however, plan on visiting with him later this week to ‘try to explain to him what’s going on.’

‘I don’t think he understands what’s happening,’ she told the outlet.

After Zarutska’s death, Dewitt had spoken with Brown, who told her they were ‘removing the chip from his brain’ and that he’d see her soon.

His sister, Tracey Brown, told Daily Mail that her brother believed the government was controlling his brain via a microchip they had inserted while he was sleeping, and that Zarutska was part of this conspiracy.

‘He was a high risk. He was not in his right mind. He was not safe for society,’ she said. ‘We know what he has been dealing with the last three years. And now an innocent woman is dead.

‘He was asking and crying for help, and no-one heard him or took him seriously. He reached a level of his mental illness that caused him to commit a heinous crime.’

Brown also dialed 911 several times, and told cops directly that he believed his brain was being controlled by a microchip.

The latest recorded incidence of this was January 19, when he was arrested for ‘misuse of the 911 system’ after he called the emergency number while police were conducting a welfare check on him.

On August 22, the 23-year-old was scrolling through her phone as she rode the train home from work at a local pizzeria when she was stabbed to death just four minutes after taking her seat.

She never saw her attacker’s face because the cold-blooded killer stabbed her from behind with a pocket knife.

Prosecutors said Zarutska was stabbed a total of three times in her neck and hands.

The crazed attacker was seen in horror surveillance footage lunging at Zarutska in surveillance footage released by police, before it skips the graphic slaughter to show him carrying a knife dripping with Zarutska’s blood as he strolled through the train carriage.

At a press conference on Tuesday, US Attorney Russ Ferguson said that Zarutska’s family declined to have her body returned to Ukraine and said she would have wanted to be buried in the US because ‘she loved America.’

Officials stepped up charges against Brown to the federal level based on Violence Against a Mass Transportation System, which carries a maximum punishment of the death penalty or life in prison without the possibility of parole.

Zarutska emigrated from Ukraine with her mother, sister, and brother to escape the war, and she ‘quickly embraced her new life in the United States,’ her family wrote in an obituary.

They also said she had managed to become fluent in English ‘within a very short time’, and ‘hoping for a new beginning’ when she came to Charlotte.

Her family said that before starting her new life in the US, Zarutska graduated from Synergy College in Kyiv with a degree in Art and Restoration.

‘She shared her creativity generously, gifting family and friends with her artwork,’ they said.

‘She loved sculpting and designing unique, eclectic clothing that reflected her vibrant spirit.
