FAMILY members of black schoolboy Jordan Edwards are demanding that criminal charges be filed against the Dallas police officer who shot him dead at the weekend.

The police department in suburban Dallas has since sacked the officer, identified as Roy Oliver, who shot and killed 15-year-old Jordan as he was riding in a vehicle after leaving a party with his two brothers and two other teenagers Saturday night.

Mr Oliver was dismissed for violating department policies in the shooting, said police chief Jonathan Haber.

Police arrived at the scene of the party to investigate an underage drinking complaint and spotted the vehicle leaving.

Mr Oliver opened fire with his rifle as the teenagers were driving away, hitting Jordan in the front passenger seat.

Police originally claimed that the teenagers’ vehicle had been reversing “in an aggressive manner” toward officers, but Mr Haber admitted on Monday that video proved that the vehicle was actually driving away.

The police department’s latest statement asserts that officers entering the house heard gunshots ring out during a “chaotic scene with numerous people running away from the location.”

As officers left the house, the vehicle backed onto a main road and drove away despite the driver being told to stop, the new statement adds.

A family statement released on Tuesday night called for disciplinary action against other officers who “extended this nightmare for those children.”

“Our family is working hard to deal with both the loss of our beloved Jordan and the lingering trauma it has caused our boys,” it said.
