No teenagers were drinking or using drugs at an April 29 party broken up by Balch Springs police, despite a 911 call that ultimately led to an officer shooting and killing 15-year-old Jordan Edwards.

This week’s revelation by a law enforcement official, who spoke on condition of anonymity, and an attorney for the boy’s family accompanied the results of Jordan’s autopsy. They say the results show the teen had no alcohol or illegal drugs in his system when he died.

Roy Oliver, the officer who shot Jordan, was later fired and arrested on a murder charge. Oliver is white, and Jordan was black.

Lee Merritt, the family’s attorney, said Jordan’s parents insisted that he and his brothers leave if there was alcohol at the party.

“That was a condition of them attending the party,” the attorney said. “If they saw anyone drinking, they had to leave.”

Oliver and another officer, Tyler Gross, were inside the party watching kids carry around energy drinks and sodas. Police found no drugs or alcohol in the house except for an empty beer bottle tossed in a kitchen trash can, the law enforcement official said.

Balch Springs police had previously said there was alcohol at the party but officers didn’t cite anyone. A woman who lived at the house but has moved has been adamant there was no alcohol.

When they heard the shots, Oliver and Gross ran outside. Oliver went to his patrol car for his rifle and Gross ran toward where he thought the shots came from.

The shots everyone heard while inside the house, investigators later learned, came from the parking lot of a nearby nursing home.

As the officers ran outside, Jordan, his two brothers and two friends were leaving in a black Chevrolet Impala that belonged to Jordan’s father.

Jordan’s 16-year-old brother, Vidal Allen, couldn’t drive down Baron Drive because it was blocked by police, so he backed up onto Shepherd Lane, court records show.

Balch Springs Police Chief Jonathan Haber initially and wrongly said Oliver fired his rifle into the vehicle because the driver was aggressively backing up toward the officers. But Haber later said body camera video actually showed the car was driving forward.

Gross ordered the car to stop and broke the car’s window with his gun. Oliver fired his rifle into the front passenger window, striking Jordan in the head. The other four boys in the car were not hurt.

The murder case has yet to go to a Dallas County grand jury. Oliver has since been indicted on two aggravated assault charges in an apparent road rage confrontation two weeks before the shooting. In that case, a woman said Oliver pulled out his gun after she rear-ended him in a traffic accident while he was off duty.

Balch Springs police have declined to release copies of the 911 call that first brought them to the party, citing an ongoing investigation.

The department has requested an attorney general opinion about whether it has to release the recording and other documents related to the shooting.
