On April 29, Oliver fired into a vehicle containing Edwards and his friends, including his brother, when the auto was leaving a party.
Police had initially said the vehicle reversed "aggressively" towards the officer, but footage discredited the claim, showing the auto driving forward, away from him. "Jordan, who sat in the front passenger seat, was struck in the head".
Two of Edwards' brothers, along with two friends, were in the auto at the time of the shooting. Following his termination, the Balch Springs police chief said Oliver had violated department policies.
After Oliver and the other officers approached the scene and began to investigate, a group of teens began to flee the area.
Haber later said the body camera footage showed the auto was driving forward - away from the officers, not reversing towards them. Hopefully, it is a message we're sending to bad police officers.

The charges against Oliver follow the indictment of three Chicago officers for interfering in the investigation of a 2014 shooting death.
Through a FOIA request, NBC News learned that Oliver had previously been suspended for anger problems and was ordered to take anger management training.
"It is important to let our community know that justice is proceeding effectively and thoroughly at the Dallas County DA's Office", said Johnson in a statement Monday.
A former police officer who shot an unarmed black teenager in the head has been indicted on a murder charge by a grand jury, prosecutors in the USA state of Texas say. The Dallas County Sheriff's Department officially charged Oliver with murder shortly after the shooting.
Oliver was indicted in June on aggravated assault with a deadly weapon by a public official for a separate, unrelated incident in which he pulled out his after he was rear-ended by another vehicle, according to the Tribune.More news: Cyber loss potential parallels hurricane risk
