Stockley, 36, was charged with first-degree murder after he shot Anthony Lamar Smith, 24, five times in 2011 following a high-speed chase. Stockley said he saw Smith holding a gun, and felt like he was in danger.

A gun found in Smith’s car only had Stockey’s DNA on it, prompting the prosecution to allege it was planted.

During the trial, Assistant Circuit Attorney Robert Steeled said that police dashcam video showed Stockley saying he was “going to kill this (expletive), don’t you know it,” before shooting Smith five times.

Stockley could have been sentenced to up to life in prison without parole. He left the St. Louis police force in 2013.
