St. Louis Man Found Guilty of 2022 Murder
February 9, 2024

ST. LOUIS, MO (February 9, 2024) — Jeffery Lamonte Lumzy, 54, was found guilty by a jury Friday of first-degree murder in the December 29, 2022, shooting death of Jeffrey Avant, 35, in an apartment in the 1800 block of Cass Avenue in the city’s Carr Square neighborhood.


Lumzy was also found guilty of first-degree burglary, unlawful possession of a firearm, stealing a motor vehicle, and armed criminal action.

Police responding to a call for a shooting were met by Deidra Prince, who lived in the apartment with her five children. The victim had been visiting Prince when Lumzy, who was the father of three of the children, entered the apartment. Lumzy told Avant to leave, sparking an argument with Prince. Lumzy left, then returned, entering the apartment after climbing over the back porch railing. He shot Avant once in the chest.


Rather than calling 911 or rendering aid for Avant, who was begging for help, Lumzy told Prince to get the children dressed. She refused to allow him to take them without her. Outside the apartment, he was forcing Prince and the children into her rental car when a maintenance worker at the apartment complex intervened. Lumzy stole the car and drove away. He abandoned the vehicle in a supermarket parking lot and fled to Chicago, where he was found and arrested months later.


Avant was taken by ambulance to a local hospital where he died.


The case was prosecuted by Special Assistant Circuit Attorneys Erin O’Brien Granger and Tiffany Becker, who were cross-designated by the U.S. Attorney’s office to assist the Circuit Attorney’s office in prosecuting homicides.


“Our office is grateful for the able assistance of the U.S. Attorney’s office in successfully prosecuting this homicide,” said Circuit Attorney Gabe Gore.

The punishment for first-degree murder is life in prison without parole.


Lumzy has a long list of prior convictions, including burglary, stealing, forgery and unlawful possession of a firearm.

ST. LOUIS, MO (May 23, 2025) — James Cody Jr., 30, was found guilty of second-degree murder and armed criminal action by a jury on Friday for the March 8, 2022, murder of Michael Kelly, 72, in the 3900 block of North 25th Street in the City’s Hyde Park neighborhood. The case stemmed from an ongoing landlord-tenant dispute. Mr. Kelly, the victim, was the landlord of a residence on the 4000 block of North 22nd Street, where Cody’s girlfriend, Deseray Rabb, had stopped paying rent. Despite a court-ordered eviction, Rabb refused to vacate the property. As the legal process unfolded, Cody, who was not listed on the lease but was the father of Rabb’s three children, began threatening Mr. Kelly. On the morning of the murder, surveillance footage captured Cody following Mr. Kelly as he drove to his office. Once parked, Cody was seen approaching the vehicle with a rifle and fatally shooting him. A Nissan Sentra rented under Rabb’s name was spotted in the area and later recovered with ballistic damage concealed by duct tape. Cody was arrested days later at a St. Louis County motel, where he and Rabb were staying with their children. The jury recommended a sentence of 25 years for second-degree murder and 10 years for armed criminal action. Cody’s sentencing is scheduled for June 27, 2025. Deseray Rabb, Cody’s girlfriend and co-defendant, was charged with accessory to first-degree murder and accessory to armed criminal action. She was acquitted by the jury. Tanja Engelhardt, Homicide Unit Chief, and Assistant Circuit Attorneys Timothy Wright and Emily Price prosecuted the case. “This was a ruthless, targeted killing over a lawful eviction. This senseless act of violence has destroyed multiple families. We will relentlessly prosecute those who choose to settle disputes with gun violence to the fullest extent of the law,” said St. Louis Circuit Attorney Gabe Gore. Cody’s case number is 2322-CR01089.
