BRIDGEPORT -Nirone “Gully Guns” Hutton was going down for fatally shooting Juan Marcano, two slugs in the 25-year-old Marcano’s back and a jury’s guilty of murder verdict made that a certainty.

What wasn’t certain until the 32-year-old Hutton opened his mouth in court Monday was where on the scale of from 25 to 60 years Superior Court Judge Maria Kahn was going to land.

“This wasn’t a fair trial, it felt like 1960s Mississippi when blacks had no rights,” Hutton exclaimed as a crowd of his family and friends nodded in agreement from the back of the courtroom. “Everybody here is pointing fingers at me but you guys railroaded me the whole time, judge you never gave me a fair trial, only in Bridgeport.”

Hutton’s lawyer, Robert Berke, attempted to explain away his client’s outburst, describing him as “passionate.”

But in the end Judge Kahn sentenced Hutton to 55 years in prison.

“This was a brutal killing,” the judge told Hutton. “The victim was lured into a building and positioned so that he was shot in the back …And the only one responsible is you, Mr. Hutton.

Marcano was found lying in a stairwell of Building 5 in the Greene Homes on Feb. 27, 2007 with two bullet holes in his back. But despite an investigation the case remained unsolved for six years. During that time Marcano’s mother, Star Beauregard, was relentless in her efforts to keep the investigation open.

Nirone Hutton decided to play god and take the life of my only son,” she tearfully told the judge Monday. Then, turning to where Hutton sat, rolling his eyes and shaking his head, she added, “You shot my son not once but twice in the back and that shows you are a coward, you left him to die like an animal.”

Senior Assistant State’s Attorney praised the work of police in the case but said it wasn’t cracked until members of the public came forward with vital information.

Witnesses during the two-week trial testified that Marcano, who did not live in the housing project, had been visiting some girls there when he was confronted by members of the Harlem 5 Star Generals, a franchise of the Bloods gang that controlled that building.

Harry said Marcano took on the leader of the gang, Garrett "Slim" Bostick, and appeared to be getting the best of him when Hutton put two 38-caliber slugs into Marcano's back.

Within hours of the shooting of Marcano, federal agents rounded up members of the gang after finding them with a cache of guns and ammo. But while Harry said Marcano, on his death bed, was able to identify Bostick as the man he fought with, he couldn't identify the shooter.

Police later got a big break when they intercepted a letter to a prison inmate from "Gully Guns," according to trial testimony.

The letter, read to the jury stated: "I redrum this (expletive). Gee got caught with the slammy after the redrum went down. I got that redrum under my belt that's crazy cause I aint trying to go to jail," police said.

Redrum is code for murder on the streets. Slammy is a gun, the prosecutor told the jurors.

Police said a fingerprint lifted from the letter was Hutton’s.

Following his arrest in October 2013, police said Hutton confessed to killing Marcano.

And on the witness stand Hutton reiterated that he had shot the victim - but he claimed he had done it in self-defense.

He claimed Marcano had been pistol-whipping his friend and out of fear that the victim was about to shoot them, he fired.
