On the afternoon of July 29, 2020, a volley of gunfire in the Walnut Park West neighborhood of St. Louis left three young men dead and two others wounded. The shooting, about 1:45 p.m. near Floy and West Florissant Avenue, was described as stemming from a dispute between two rival groups. Eighteen-year-old Daijon Nearing was one of the three killed; the others were 22-year-old Malik Taylor and 18-year-old Elijah McKinney. A 17-year-old boy and a 37-year-old man suffered nonfatal gunshot injuries.

St. Louis Metropolitan Police homicide detectives arrested 17-year-old Joshua Amerson in November 2020, charging him with counts that included first-degree murder, second-degree murder, first-degree assault, unlawful use of a weapon by shooting from a motor vehicle, and multiple counts of armed criminal action. Prosecutors dismissed those charges in July 2022 to permit additional preparation, and the murder case was dismissed again in June 2023, authorities citing a lack of witness cooperation. Shortly after the June 2023 dismissal, Amerson was arrested on separate drug trafficking allegations after being found with a large quantity of fentanyl.

Did anyone in the Walnut Park West area hear or see anything that afternoon that might still be useful to investigators?
