RALEIGH — A man who has spent the past seven years in a psychiatric hospital pleaded guilty today to second-degree murder in connection with a 2001 shooting in a Southeast Raleigh duplex.

Dwayne Haywood, 29, has been at Dorothea Dix Hospital since shortly after his arrest in 2001 and was considered too mentally ill to be tried in court until recently. At one point he believed he was the sixth member of the family pop quintet the Jackson 5.

Haywood pleaded guilty to fatally shooting Abraham “Blackie” Payne, 22, in Payne’s home at 324 Maple St. just before midnight on June 19, 2001. Superior Court Judge Orlando Hudson sentenced Haywood to 13 years in prison, giving him credit for the seven he’s already spent in the state psychiatric hospital.

Wake assistant district attorney Howard Cummings said that, after the shooting, Haywood took another man at gunpoint and made him drive to the Raleigh-Durham International Airport — despite not having a ticket and the airport being closed for the night.

There, Haywood threw his gun into a trash can and was arrested by police. The connection between Payne, the victim, and Haywood was unknown, but both men were from Brooklyn, N.Y. Cummings said in court that when Haywood confessed to the shooting in 2001 he told police that he was seeking revenge for an assault that had occurred outside of North Carolina.

But Haywood’s mental stability has been questionable since a young age, according to a psychiatrist's report submitted to court today.

He was first classified as “emotionally disturbed” in 1990, when he was 11, and was placed in special education classes. When he was 16, he was imprisoned for an attack at a Rite-Aid pharmacy where he ransacked the store and then slashed three people with a box-cutter, causing one victim to need 120 stitches, according to the report written by Nicole Wolfe, a forensic psychiatrist.

Haywood was hospitalized in a psychiatric center in 2000 in Central New York, where he spoke of being the creator and had violent behavior.

In 2001, Haywood again was arrested, this time for armed robbery, and went back to psychiatric hospitals in New York. He told psychiatrists there that he thought he was the Jackson 6, the biological brother of Michael Jackson. He also thought he as the “Chosen One” and was diagnosed with bipolar disorder.

Haywood was released on May 30, 2001 and last visited a New York psychiatric center on June 11, 2001. Eight days later, he was in Raleigh and shot Payne.

Since July 2001, Haywood has been at Dix after beings declared incompetent to stand trial, according to the psychiatric report. He has been taking medication for years to stabilize his mental state and no longer has delusional beliefs, Wolfe wrote.
