Joaquin Trujillo, 35, was shot and killed just before dawn on May 24, 2025, after an argument that began between his car and another vehicle in Humboldt Park. Around 2:45 a.m. in the 1700 block of North Spaulding Avenue, Trujillo stepped out of his car and the other man, still inside his vehicle, opened fire, striking Trujillo multiple times. Witnesses told police the shooter left in an older-model gray Infiniti sedan and Trujillo was taken to Stroger Hospital, where the Cook County medical examiner confirmed his death.

Police opened an investigation and, in the immediate aftermath, announced no arrests and publicly identified no suspects by name beyond the fleeing-vehicle description. His killing was also noted among incidents that prompted an increased police presence over the Memorial Day weekend. If anyone saw the confrontation near North Spaulding Avenue that night or has information about the gray Infiniti, contact investigators.
