Cheri Simpson, 32, was shot and killed during downtown St. Louis rush hour on January 15, 2015. She was driving with her current boyfriend and another male passenger when her ex-boyfriend, 49-year-old Willie Barnes, began pursuing their car. At a red light at S. Tucker Boulevard and Chouteau Avenue, Barnes pulled alongside Simpson’s vehicle, exchanged words, then opened fire, striking Simpson in the shoulder and chest and wounding her boyfriend in the hands. Simpson was taken to a hospital and died of her injuries.

Police arrested Barnes within 90 minutes of the shooting and recovered a .38 special revolver investigators believed to be the weapon used. He was charged with first-degree murder, two counts of armed criminal action, first-degree assault, and shooting a firearm at a motor vehicle. Prosecutors emphasized the pursuit as evidence of premeditation leading to a conviction.
