Roy Oliver, 37, fired a rifle into a auto that was driving away from a party in the Dallas suburb of Balch Springs in April, killing Jordan Edwards, 15. Originally, Police Chief Jonathan Haber claimed that the vehicle was reversing toward Oliver in a menacing manner, but that account was later corrected to state that the auto was moving forward instead.
Johnson said Oliver also was indicted on four charges of aggravated assault with a deadly weapon by a public official related to the other four teens who were in the auto. The bullets shattered the front passenger-side window and struck Edwards.
Oliver joined the Balch Springs department in 2011 after being an officer with the Dalworthington Gardens Police Department for nearly a year.
The charges against Oliver follow the indictment of three Chicago officers for interfering in the investigation of a 2014 shooting death.
Oliver, who was a member of the police department for six years, was sacked in May.
Last month, Oliver was indicted on two counts of aggravated assault with a deadly weapon by a public servant in an unrelated incident, where he is accused of displaying a gun during a traffic accident.
“It is important to let our community know that justice is proceeding effectively and thoroughly at the Dallas County District Attorney’s office”, Faith Johnson, the district attorney, told a news conference, adding that her department will prosecute the case vigorously.
The Dallas County Sheriff’s Department charged Oliver with murder in May, less than a week after the shooting. No date has been set for the trial.
A former Dallas suburb policeman was indicted on Monday by a grand jury for murder for using a rifle to kill a black teenager in a vehicle moving away from the officer, in a case fueling a national debate over possible racial bias in USA policing.
