On the evening of December 29, 2018, 22-year-old Wanyaa Stewart was at a Mobil gas station at Baseline Road and Mill Avenue in Tempe, Arizona, trying to put air in a flat tire when he was fatally shot. His girlfriend was with him and witnessed the shooting. Wanyaa was the younger brother of Arizona State University forward Zylan Cheatham.

Tempe police investigators reported a history of conflict between Stewart and another man, 25-year-old Dantreil Griffin, and said the shooting may have been gang-related. Video surveillance and cell phone tracking were used to tie two individuals to the incident. In January 2019, authorities arrested Dantreil Griffin in Laveen on a first-degree murder charge. In February 2019, a second suspect, 25-year-old Corey Winston Jr., was taken into custody in Phoenix; investigators alleged he was the driver of the vehicle used to flee the scene.

Did anyone see Wanyaa or his car near Baseline and Mill on December 29, 2018, or have information about that evening?
