The Case File
Before Mtayari Dixon’s name appeared on an FBI wanted poster, the case began as a homicide call in New Rochelle, New York, just before 6 p.m. on October 26, 2022. Police were sent to the area of Horton Avenue and Colonel Lee Archer Boulevard after multiple calls reported shots fired and a person shot. When officers arrived, they found 29-year-old James Caldwell Jr. on the ground with multiple gunshot wounds. Police, fire, and ambulance personnel rendered aid, but Caldwell later died at a local hospital.
The FBI now identifies Dixon as wanted for Unlawful Flight to Avoid Prosecution — Murder. The federal file alleges that Dixon shot the victim after a verbal altercation, then left New Rochelle by train, first heading to Stamford, Connecticut, before possibly moving through Atlanta, Georgia, and Charlotte, North Carolina. The FBI is offering up to $10,000 for information leading to Dixon’s location and arrest.
This is not a closed murder file. It is a fugitive case still sitting in public view, with a local homicide, a state murder warrant, a federal flight warrant, surveillance claims, and a suspect the FBI says should be considered armed and dangerous.
The Victim: James Caldwell Jr.
The victim was James Caldwell Jr., 29, of New Rochelle. New Rochelle Police publicly identified him after the shooting and asked anyone with information to contact detectives.
Outside the police release, Caldwell was widely identified in local coverage and America’s Most Wanted-related reporting as Boogie Nation, a rapper from New Rochelle. That music connection later became part of the public story around the case, but the official police release does not describe the motive, the music history, or any prior conflict between Caldwell and Dixon. The verified record starts with the shooting location, the emergency response, the fatal injuries, and the later warrant.
That separation matters inside this file: James Caldwell Jr. is the confirmed homicide victim. “Boogie Nation” is the public identity attached through later reporting. The music-dispute version exists in media coverage, but the official FBI summary only states that the shooting allegedly followed a verbal altercation.
The Shooting On Horton Avenue
At about 5:54 p.m., New Rochelle Police received multiple calls for shots fired near Horton Avenue and Colonel Lee Archer Boulevard. The first police language is direct: a person had been shot, officers arrived, and the victim was located on the ground with multiple gunshot wounds.
The location is important because later reporting places the shooting close to central New Rochelle landmarks and a possible escape path toward the Metro-North station. The police release itself does not provide a frame-by-frame account of the shooting. It does not say how many shots were fired, where the shooter stood, or what Caldwell was doing before the gunfire. It confirms only the call time, the intersection, the victim’s injuries, the emergency response, and the death.
The FBI adds the next layer. According to the federal wanted page, Dixon is alleged to have shot the victim after the two were involved in a verbal altercation. That wording keeps the motive narrow. It does not say robbery. It does not say gang retaliation. It does not say a planned ambush. It says an altercation allegedly came before the shooting.
The Wanted Suspect
The FBI lists Mtayari Dixon with a date of birth of December 20, 1992. The federal description places him at 6’1” and 235 pounds, with black hair that may be shaven or bald, brown eyes, and a tattoo of a man’s face on his upper left arm. The FBI says Dixon has ties to New Rochelle, Stamford, Atlanta, and Charlotte.
New Rochelle Police described Dixon in their warrant update as formerly from New Rochelle and known to reside in Stamford, Connecticut. The city’s warrant notice said the arrest warrant called for full extradition from any U.S. state.
Dixon is not listed by the FBI as wanted for questioning. He is listed as wanted after being charged with murder in New Rochelle City Court and after a federal unlawful-flight warrant was issued in the Southern District of New York.
The State Murder Warrant
New Rochelle detectives obtained an arrest warrant tied to the October 26, 2022 homicide. The city’s public update named Dixon as wanted for murder and identified Caldwell as the victim. That update was posted on October 26, 2023, one year after the shooting.
The FBI file gives the charging date: November 14, 2022. According to the FBI, Dixon was charged with murder in New Rochelle City Court, and a state warrant was issued for his arrest.
That means the murder charge came quickly after the shooting. The case did not sit for years before a suspect was named. Within weeks, Dixon had been charged at the state level. The larger problem became finding him.
The Federal Flight Warrant
The federal piece entered later. On March 8, 2024, a federal arrest warrant was issued in the United States District Court for the Southern District of New York in White Plains after Dixon was charged with unlawful flight to avoid prosecution.
That federal charge changes the shape of the case. A local homicide investigation becomes an interstate fugitive matter. Once investigators believe a murder suspect has crossed state lines, the case no longer belongs only to New Rochelle detectives. It becomes a federal search with multiple possible destinations, a public wanted poster, and a reward meant to pull information from outside New York.
The Alleged Escape Route
The FBI’s version of the escape route is clean and direct. After the murder, Dixon is believed to have boarded a train and gone to Stamford, Connecticut. From there, he may have boarded a bus to Atlanta, Georgia, then traveled on to Charlotte, North Carolina.
New York State Crime Stoppers published a more detailed public-tip narrative in 2022. That account said Dixon allegedly fled on foot, was last observed on video surveillance entering a northbound Metro-North train in New Rochelle, and later entered his residence in Stamford, Connecticut. Crime Stoppers also listed a last known address on Tresser Boulevard in Stamford and said Dixon was not known to drive and may use public transportation.
That detail gives the case its strongest movement: Horton Avenue, the walk away, the northbound train, Stamford, then the possible bus route south. The FBI confirms the broader route. Crime Stoppers gives the public-facing surveillance and transportation details. The final case file should treat those as connected but not identical sources.
The Evidence Named Publicly
The official New Rochelle release confirms multiple gunshot wounds and a fatal shooting scene. It does not list shell casings, caliber, firearm recovery, or surveillance details.
New York State Crime Stoppers reported that New Rochelle detectives recovered several 9mm casings from the scene and that the firearm had not been recovered. The same Crime Stoppers notice said Dixon used the aliases “MT” and “MT Beats.”
Those details are valuable, but they should be handled carefully. They are public law-enforcement-adjacent tip information, not a full murder report, not an evidence inventory, and not a court affidavit. The public record does not currently show the recovered weapon, ballistic testing, autopsy findings, or a detailed police narrative explaining how detectives connected Dixon to the shooting beyond the warrant, surveillance references, and public wanted materials.
The CCTV Trail
The most visual part of the case comes from later America’s Most Wanted-related coverage. Talk of the Sound reported that New Rochelle Police Sergeant Tim Adrian appeared on America’s Most Wanted and that the episode included never-before-released CCTV footage. According to that report, the footage allegedly shows Dixon shooting Caldwell, Caldwell running a few steps and collapsing, and Dixon walking away through New Rochelle toward the Metro-North station.
That same report described the route as moving along Colonel Lee Archer Boulevard, onto Horton Avenue, across Brook Street, onto North Avenue near New Rochelle City Hall, past KFC and New Rochelle Police Headquarters, and toward the Metro-North station.
This is the part that makes the case feel like a fugitive timeline instead of a static wanted poster. The shooting does not end at the scene. The public reporting follows the alleged movement away from the body, through the city, toward transit, and then out of New York.
The America’s Most Wanted Layer
Patch reported that the Dixon case was featured on America’s Most Wanted and that investigators hoped national attention and the FBI reward would help put him in custody. Patch also repeated the law-enforcement version that Dixon was accused of fatally shooting Caldwell after an argument on Horton Avenue, then possibly traveling through Stamford, Atlanta, and Charlotte.
Talk of the Sound’s recap of the episode adds another layer: a reported music dispute. That recap claimed Dixon and Caldwell had a music connection, that Dixon made beats, that they worked together, and that tension allegedly developed after a failed collaboration.
That claim should not be written as the official motive unless a direct police transcript, court document, or full episode transcript confirms it cleanly. The FBI’s official motive language remains much narrower: a verbal altercation before the shooting. The music-dispute version belongs in a separate section as a reported America’s Most Wanted/media claim.
Official Facts Versus Reported Claims
The official facts are clear. James Caldwell Jr. was shot near Horton Avenue and Colonel Lee Archer Boulevard on October 26, 2022, at about 5:54 p.m. He suffered multiple gunshot wounds and died after being transported to a local hospital. New Rochelle Police obtained an arrest warrant for Mtayari Z. Dixon, and the FBI later listed Dixon as wanted for unlawful flight to avoid prosecution in connection with murder.
The official FBI file also states that Dixon allegedly shot the victim after a verbal altercation, then is believed to have gone by train to Stamford and possibly by bus to Atlanta and Charlotte.
The additional public claims include the 9mm casings, aliases “MT” and “MT Beats,” the northbound Metro-North surveillance sighting, the Stamford residence detail, and the unrecovered firearm. Those come from New York State Crime Stoppers.
The most detailed surveillance route and music-dispute narrative come from America’s Most Wanted-related reporting by Talk of the Sound. Those details make the case more complete, but they should stay labeled as reported TV/local coverage unless supported by a court record or official transcript.

Open Questions In The Public Record
The public record does not show a full murder report, a court affidavit, an autopsy report, or a ballistics report. Without those documents, several major questions remain limited to partial public information.
The public file does not explain exactly what witnesses told detectives after the shooting. It does not reveal whether any eyewitness identified Dixon at the scene. It does not show the full surveillance chain or whether investigators recovered camera footage from every point along the route. It does not identify the firearm. It does not explain whether the recovered casings were tested against any other cases. It does not show whether phone data, transit records, license plate readers, or bus records were used in the investigation.
The FBI’s wanted page gives enough to establish the allegation and fugitive route. New Rochelle Police confirm the homicide and warrant. Crime Stoppers adds evidence and alias details. America’s Most Wanted coverage adds the strongest visual and motive claims. But the deeper investigative file remains mostly sealed from public view.
Final Breakdown
The Mtayari Dixon case sits between a local homicide file and a national fugitive search. The first layer is the official homicide: James Caldwell Jr., 29, shot near Horton Avenue and Colonel Lee Archer Boulevard on October 26, 2022. The second layer is the murder warrant: New Rochelle detectives identified Mtayari Z. Dixon as the wanted suspect. The third layer is the escape route: the FBI says Dixon left New Rochelle by train to Stamford, then may have moved south through Atlanta and Charlotte.
What makes this case different from a standard wanted poster is the alleged trail. Public reporting does not just say Dixon disappeared. It places him moving from the shooting scene toward transit, then into another state, then possibly deeper into the South. The public version of the case becomes a manhunt built around trains, buses, surveillance, aliases, and cities where someone may still know where he went.
As of the FBI’s public wanted file, Dixon remains wanted for unlawful flight to avoid prosecution in connection with murder. The agency lists a reward of up to $10,000 and warns that he should be considered armed and dangerous.
