In the early moments of September 6, 2025, a house party on Denver's east side spilled out into a dimly lit parking lot in the 1100 block of North Syracuse Street. Shortly after midnight, the gathering was shattered by the sound of gunfire. When the chaos subsided, 13-year-old Ja’Loynie Cosey, a Black male, was found gravely wounded. Emergency services arrived at the scene around 12:12 a.m. and rushed the young boy to a hospital, but his injuries were too severe, and he was pronounced dead.
The Denver Office of the Medical Examiner would later confirm that the cause of death was a gunshot wound, ruling it a homicide. Ja'Loynie had just begun his eighth-grade year at DSST: Montview Middle School.
The investigation into the shooting moved swiftly. Denver police investigators believed the incident was connected to the house party. Within days, they announced a significant development: a juvenile suspect had been taken into custody and was being held for investigation of first-degree murder. Because of the suspect's age, authorities did not release a name. It was later revealed that prosecutors had filed first-degree murder charges against a 14-year-old boy in connection with Ja'Loynie's death. The Denver District Attorney's office also signaled its intention to seek the transfer of the case from juvenile to adult court. While an arrest was made, officials have not publicly detailed a motive for the shooting, and it is not known if any other individuals are being investigated. Investigators have stated they believe Cosey was an innocent victim.
Ja'Loynie, affectionately known as 'Taz' to his friends and family, was remembered as a vibrant and ambitious young man. He was a standout student, consistently earning all-A's. He had a passion for basketball, playing with enthusiasm for the Gold Boys AAU and RISE teams. His coach, Jay Cain, recalled him as a 'beast on the court,' full of energy and unafraid to fail. His teammates honored his memory by signing a basketball for his family and adopting a new pre-game chant: 'One-two-three – Taz; four-five-six – family.' Beyond sports, he had an interest in the arts and music and had even talked about one day pursuing acting. His life, full of promise, was tragically cut short, leaving his family, friends, and community to mourn the profound loss.
