A former St. Louis police officer is facing first-degree murder charges in the 2011 fatal shooting of a driver authorities said was believed to have been involved in a drug deal.
New video of the incident, obtained by several news outlets, appears to show the officer pointing a personal weapon at the driver and then, after the shooting, rummaging through a duffle bag in his patrol car before returning to the crime scene.
According to Fox 2 Now, then-Police Officer Jason Stockley attempted to stop the driver, Anthony Lamar Smith, after a reported drug deal.
In video viewed by the news station, Stockley exits his patrol car carrying an AK-47. The news station notes that the weapon was Stockley's personal assault rifle and that carrying it during a traffic stop was a direct violation of St. Louis Police Department policy.
In the video, Smith can be seen speeding away in his car.
Prosecutors say that Stockley shot at Smith's car before giving chase. It is unclear whether the officer shot the assault rifle or his service weapon.
With another officer driving, Stockley follows Smith in a patrol car, according to the report. "A speed monitor on the dashcam video clocks the officers exceeding 80 miles per hour on wet streets and speeding past stop signs," the news station reports.
At one point, the officers miss a turn and hit a tree.
"Back up," Stockley is heard yelling.
While additional audio on the video is unclear, the St. Louis Circuit Attorney's Probable Cause Statement indicates that Stockley then said, "Going to kill this [motherf—ker], don't you know it."
Smith appears to slow down and Stockley can be heard yelling, "Hit him right now."
The officers ram the back of Smith's car and then surround him. The probable cause statement viewed by the news station indicates that Stockley then fired five shots into the car, killing Smith.
At the end of the video, Stockley is seen rummaging through a bag in the back of a squad car.
Police reported finding a gun on Smith, but prosecutors charge it "was later determined by lab analysis to have only [Stockley's] DNA on it," Fox 2 reports.
"The people of the city of St. Louis have a right to determine whether the state has proven its case beyond a reasonable doubt," the circuit attorney's office said in a statement. "The courtroom is the appropriate forum for this matter."
Stockley's attorney, Neil Bruntrager, told the news station that the video is just one piece of evidence and that a surveillance video that is not available to the public shows a different perspective.
