Officer Josh Hastings was fired from the Little Rock Police Department on October 19.
LRPD says that Hastings was fired on the bases of "several departmental policies."
On August 12, Hastings shot and killed 15-year-old Bobby Moore, a teenager who was allegedly breaking into vehicles.
Hastings claimed that he shot at the car Moore was driving toward him, but further investigations showed that the vehicle was actually backing up at the time of the shooting.
Hastings was arrested for manslaughter in September.
