Martin Guerrero was driving through Chicago’s Humboldt Park in the early hours of August 24, 2025, when a crash on the 3800 block of West Chicago Avenue brought his car to a stop. According to police, another vehicle pulled up, its driver stepped out and shot Guerrero several times in the chest; he was rushed to Stroger Hospital and pronounced dead that morning.

Detectives said the attack happened immediately after the crash. By that day’s end no one was in custody; investigators canvassed the stretch of West Chicago Avenue for witnesses and video, and described the shooter only as an unknown assailant. In September, Cook County Crime Stoppers offered a $10,000 reward for information leading to an arrest or indictment, and police reiterated that no motive had been publicly identified as the probe continued.

Guerrero lived in Morris and was memorialized by family in an obituary; community gun-violence trackers added him to the 2025 victim rolls. If anyone saw the crash or the vehicle that pulled up around 1:45–2:00 a.m., please share what was observed with investigators.
