The terminated Balch Springs officer who fatally shot 15-year-old Jordan Edwards was indicted Monday on one count of murder and four counts of aggravated assault with a deadly weapon by a public servant.

Joined by Edwards' family, Dallas County District Attorney Faith Johnson held a news conference Monday afternoon to discuss the indictment of former Officer Roy Oliver, 37. The district attorney said the indictment wasn't a political statement.

"We have some great police officers," she said. "... You've heard me say this over and over and over again. I support our police officers. But I think good police officers would stand with us and say, 'We do not condone bad behavior.' ... So this isn't a message we're trying to send to our good police officers. Hopefully, it is a message we're sending to bad police officers. If you do wrong, we will prosecute you."

Edwards was in the passenger seat of a car with his brother and friends when he was fatally wounded by shots fired by Oliver as the teens left a party on April 29.

The four aggravated assault charges were for the four teens inside the vehicle, Johnson said.

Just after the shooting, Balch Springs Police Chief Jonathan Haber said Oliver fired the shots as the car carrying the teens reversed back towards officers. However, Haber later said after a review of video captured at the scene, that the car was headed away from the officers.

Oliver was terminated and charged with murder in May.

"It is important to let the public know that justice is proceeding effectively and thoroughly at the Dallas County District Attorney's Office," Johnson said of Oliver's indictment. "This is the very first time we've issued an arrest warrant for a police officer before the case was presented to the grand jury."

In late June, Oliver was indicted on two counts of aggravated assault involving a separate case that occurred before the Edwards shooting.

In that case, a woman alleged Oliver pulled out a gun during a fender bender.

In the Edwards' case, Oliver faces up to life in prison. He was released from jail on a $700,000 bond.
