Quincy Jay Polk, a 30-year-old Black man, was shot and killed during a road-rage confrontation in a Lowe’s parking lot near 19th Avenue and Baseline Road in south Phoenix. On the afternoon of November 22, 2025, police say an argument between drivers escalated into a physical fight and then gunfire. Polk was driving a white SUV with his fiancée and their three young daughters; he was pronounced dead at the scene. One daughter, 8-year-old Envy Cardenas, was critically injured, taken to the hospital, and later died from her wounds.

Investigators say the dispute began as aggressive driving or tailgating between Polk’s SUV and a gray Dodge and continued into the parking lot. Witnesses reported both drivers fought, Polk’s fiancée became involved, then everyone returned to their vehicles. Police say the other driver retrieved a handgun, shouted a threat, and fired multiple rounds into the SUV, striking Polk, his fiancée and two children.

Authorities identified and arrested 28-year-old Tyrone Dee Chilly; court records show he was booked on November 24, 2025, on two premeditated first-degree murder charges and related counts, with bond set at $3 million. Police say they are not seeking additional suspects. If anyone witnessed the incident or has information about what led to the confrontation, please come forward.
