CHARLOTTE — The anguished mother of accused Charlotte train killer Decarlos Brown Jr. said she tried to get her schizophrenic son help — but was turned away.

In an exclusive interview with The Post, Michelle Dewitt also asserted that he should never have been walking free as his mental health was rapidly deteriorating.

“He shouldn’t have been released,” Dewitt, 51, said of him being free on a “written promise” to appear for a court date after his latest arrest in January.

Dewitt said she had taken her son to a homeless shelter just days before the barbaric caught-on-camera stabbing of 23-year-old Ukrainian refugee Iryna Zarutska — and that he had grown increasingly aggressive with both her and her husband.

She batted down claims Brown allegedly attacked Zarutska because she was white, saying he was “definitely not racist” and that he “dated all kinds of girls.”

Despite efforts to get her son help, Dewitt said she encountered resistance along the way.

“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 said outside her home Wednesday.

Dewitt said she plans to visit Brown in jail later this week.

“I’ll let him talk, just listen. I’ll try to explain to him what’s going on. I don’t think he understands what’s happening.”

She said she spoke to him on the phone about the murder after his arrest, and that Brown was convinced someone was “removing the chip from his brain” that had been controlling his actions and believed he’d be out soon.

“I think he misunderstood. He said, ‘Mama, I will see you later,’” she said.
