BALCH SPRINGS, Texas – The fired Balch Springs police officer who shot and killed a 15-year-old in a car leaving a party has been charged with murder, law enforcement officials confirmed to FOX4.

The murder warrant for Roy Oliver was signed Friday afternoon by a Dallas judge. Oliver is expected to surrender with his attorney.

LET previously reported that Jordan Edwards, a Mesquite High School freshman, was shot while he was in a car that was leaving a party Saturday night.

Initial reports from the police department indicated the vehicle was backing aggressively toward officers. Yet the body camera footage told a different story, forcing the chief to publicly rescind a preliminary statement.

Chief Jonathan Haber fired Oliver on Tuesday saying he “violated several department policies.”

Throughout the week pressure has been building for a murder charge against Oliver. The Texas Legislative Black Caucus joined other voices Thursday in calling the shooting a murder and wanting Oliver arrested.

“It really is murder at the end of the day,” said State Rep. Helen Giddings (D-Duncanville).

UPDATE: Oliver turned himself in Friday night, just hours after the Dallas County Sheriff’s Office issued a warrant for his arrest in the April 29 death of Edwards. He was later released after posting bail at the Parker County Jail. His bond had been set at $300,000.
