Terrenzalo Walker, 22, was shot and killed on July 4, 2016, in the Peabody Darst Webbe neighborhood of Saint Louis, Missouri. The shooting occurred during a fight in the 1400 block of Lasalle Lane on a holiday that saw multiple violent incidents across the city. Walker died of his gunshot wounds after police brought the scene under control.

The St. Louis Metropolitan Police Department investigated and arrested two teenagers, 19-year-old Donnell Smith and 18-year-old Marcello Mahone, on charges of assault and armed criminal action tied to the broader altercation. Multiple eyewitnesses later placed Smith and Mahone at the scene and said they were armed and firing, but no witness identified either as having shot Walker, and no murder charge for Walker was brought at that time.

Anyone with information about what happened that night or who fired the fatal shot is asked to come forward.
