UPDATE May 11, 8:20 p.m.:
The Justice Department has launched an investigation into the fatal shooting of a black 15-year-old by a white police officer, a spokeswoman for the Dallas County District Attorney's Office confirmed Thursday.
The investigation is separate from the district attorney's prosecution of the officer, Roy Oliver, on a murder charge.
A Justice Department official said the investigation could end in a variety of outcomes--some civil, some criminal.
Oliver was fired from the Balch Springs police department and charged with murder from the April 29 incident. He is free on bond.
ORIGINAL STORY: Jordan Edwards' family is suing the former Texas police officer accused of shooting and killing the 15-year-old.
Jordan was shot on April 29 while riding in a car with his brothers after leaving a house party. Balch Springs police officer Roy Oliver was charged with murder in connection with his death.
In the 22-page lawsuit that was filed in U.S. District Court in Dallas late last week, Jordan's family argues that Oliver used excessive force.
"Oliver's violent temper, a fact defendant City of Balch Springs was aware of or should have been aware of, led to the wrongful death of Edwards," the lawsuit stated.
The court filing, according to CNN, also noted that the Dallas County District Attorney's Office had previously filed a complaint about Oliver's "aggressive behavior." Jordan's father, Odell Edwards, argues in the lawsuit that city leaders "failed to properly, train, supervise, screen, discipline, transfer, counsel or otherwise control officers" known to use excessive force.
Odell Edwards argues in the lawsuit that city leaders "failed to properly, train, supervise, screen, discipline, transfer, counsel or otherwise control officers" known to use excessive force.
The use of force policy for the Balch Springs Police Department falls in line with national recommendations that instruct officers to avoid shooting at moving vehicles unless their lives or the lives of others are at risk.
Friends and family gathered for Jordan's funeral Saturday.
