More updates on the unfortunate killing of 15-year-old Jordan Edwards have come down the pipeline.

We previously reported that Balch Springs police officer Roy Oliver, a white man, was fired after he shot and killed the unarmed black teen on the fateful April 29.

Oliver has since been charged with murder by Dallas prosecutors, and the U.S. Department of Justice has opened an investigation on the case, Reuters reports. The investigation was confirmed via email from Brittany Dun, a spokeswoman for the Dallas County District Attorney's Office.

According to court papers, Oliver responded to reports of underage drinking at a house party in Balch Springs, along with another officer. Balch Springs is a predominantly black and Hispanic community about 15 miles from Dallas.

After hearing gunfire, the two officers approached Oliver and his two brothers in a sedan at an intersection, and one of the officers told the driver to stop. As they drove past the officers, Oliver shot into the sedan with a rifle, delivering a fatal blow in the head to Edwards. Edwards was later pronounced dead at a local hospital.

After being dismissed by Balch Springs police, Oliver turned himself in on May 5 to face a murder charge. He was later freed on bail, having paid $300,000. In addition to the pending investigation, Edwards' father is suing Oliver and Balch Springs, alleging his son was the victim of excessive force.

The Department of Justice has a history of investigating police departments and officers’ use of force to uncover possible civil rights abuses.

The Dallas Morning News previously cited two unnamed law enforcement sources alleging that the gunfire the two Balch Springs officers heard and responded to came from the parking lot of a nursing home in the area. They also noted that those bullets were likely fired in the air. Investigators recovered shell casings from that very lot, although it remains unclear who fired those shots.

Though it shouldn't need to be said in terms of whether his life was worth living, Edwards has been described by both friends and family as a good student and athlete. According to the family's lawyer, this tragic murder has also affected Edwards' brothers, who had to watch him die in the car.

We hope that the investigation brings further light to this story for the sake of the Edwards family.
