Prince Johnson, 43, a Black man from Chicago, was found shot multiple times around 9:40 p.m. on July 11, 2025, on the 13200 block of South Langley Avenue in the Riverdale community on the Far South Side. Officers and paramedics pronounced Prince Johnson, 43, dead at the scene that night, and early reports noted there was no one in custody as Area Two detectives opened a homicide investigation.
In the weeks that followed, detectives pieced together what prosecutors would later describe as a calculated ambush. Authorities allege that the victim, Prince Johnson, 43, was lured to the Altgeld Gardens area for a meeting and then executed. Prosecutors said the accused used a phone number tied to his electronic monitoring agreement to arrange the encounter; at the time, he was already on pretrial release from a separate case and wearing an ankle monitor.
On August 6, 2025, nearly a month after the killing, Chicago police arrested 38-year-old John Perteet near his West Garfield Park home. He was charged with first-degree murder in the death of Prince Johnson, 43, and ordered held while awaiting trial. Police and court records indicate the arrest took place in the 4400 block of West West End Avenue, and charging documents tie Perteet to the July 11 shooting on South Langley.
Community memorial pages and violence-tracking databases later recorded the loss of Prince Johnson, 43, on July 11, 2025, noting the fatal shooting in Chicago and preserving his name among the year's homicide victims while the case moved through the courts.
