Daisy Martinez was 19 when she was killed on the night of September 16, 2020, while attending Mexican Independence Day celebrations along Southwest Boulevard in Kansas City, Missouri. A large crowd had gathered for a street festival and car show near West 27th Street when a disturbance erupted shortly before 11:00 p.m. Surveillance footage shows two men run toward a black Chevrolet Silverado in a nearby parking lot; one retrieved a chrome AK-47 and opened fire as the crowd scattered. Martinez was struck and later died at a hospital; another woman was wounded and survived.

Police tracked the distinctive truck, pursued it, and arrested the vehicle owner and a passenger, identified as 30-year-old Diego Calderon-Guzman. Investigators recovered the rifle from the truck and ballistics testing matched casings at the scene. The owner pointed to Calderon-Guzman as the shooter; Calderon-Guzman, a convicted felon who admitted firing the weapon, told police he believed he was being shot at and did not see Martinez in his line of fire. Prosecutors charged him with second-degree murder, unlawful use and possession of a weapon, and two counts of armed criminal action.

Did anyone who attended the Southwest Boulevard celebration that night notice the black Chevrolet Silverado or the two men near the parking lot?
