Here is a timeline of events beginning with the fatal shooting and up to the current protests.
Stockley graduated from West Point Academy, a spokesman for the military prep school said.

Dec. 20, 2011:
Stockley, then 36, had five years of service as a St. Louis police officer. He and his partner, Officer Brian Bianchi, both white men, moved in on what they said they suspected was a drug buy happening in the parking lot of a fried chicken restaurant in the Walnut Park West neighborhood.
The two officers drove up to the scene and attempt to barricade Smith, who was black, with their police SUV.
Both Bianchi and Stockley exited the SUV, with Stockley wielding what state prosecutors later said was his "personal" unsanctioned Draco AK-47 rifle.
Then, according to the prosecution's court documents, Stockley switched from the rifle to his police-issued Beretta and "fired seven shots at the fleeing car."
However, Smith managed to elude them while behind the wheel of his Buick, according to dashcam video.
The policemen gave chase with Bianchi driving and Stockley sitting in the front passenger seat.
Stockley is heard yelling, "Get him!" and breathing heavily as he informs a dispatcher multiples times that "shots were fired," according to dashcam video footage.
During the pursuit, the police car crashed into a street sign and the base of a tree.
Suffering only minimal damage, officers continued pursuing Smith. As they closed in, Stockley is heard saying, "Going to kill this mother---, don't you know it," according to the video footage and court documents.
Bianchi then sped through various street intersections and Stockley is heard saying, "Hit him right now."
Their cruiser rear ends Smith's car and forces it to spin to a stop near the intersection of West Florissant Avenue and Goodfellow Boulevard in north St. Louis, according to Stockley's radio dispatch.
Stockley exited the SUV and rushed over to the driver's side of Smith's Buick.
He unholstered his Beretta pistol, according to court documents, claiming that Smith ignored his commands to show his hands and instead was reaching for what Stockley said he suspected was a gun.
Fearing he was in imminent danger, he said, Stockley fired his Beretta at the vehicle five times, striking and killing Smith.
Prosecutors accused Stockley of planting the .38 revolver found in Smith's car. Stockley's DNA, according to court documents, "was on every weapon he touched. Anthony Smith's DNA was not on any."
Stockley was detailed to desk duty as St. Louis Police Chief Dan Isom asked for an FBI investigation of the incident.
A wrongful death lawsuit was filed against the St. Louis Police Board and Stockley, with Smith's 1-year-old daughter Autumn as plaintiff, according to the St. Louis Post-Dispatch.
St. Louis Circuit Attorney Jennifer Joyce and then-U.S. Attorney Richard Callahan met to discuss the case. Afterwards, both cited insufficient evidence and no charges were filed against Stockley.
Stockley was suspended without pay for 30 days when he is found to be in violation of pursuit and use-of-force policies in the Smith case, after new St. Louis Police Chief Sam Dotson takes office. Stockley resigned from the police force.
Stockley relocated to Houston, Texas, and takes a civilian position at an oil drilling inspection firm.
The St. Louis Board of Police Commissioners settled the wrongful death lawsuit for $900,000.
