DALLAS (AP) -- A grand jury has declined to bring charges against Dallas police officers responsible for the death of a sniper who had killed five officers during a downtown rally.
The Dallas County District Attorney's office said in a statement Wednesday that investigators presented their findings to a grand jury more than a year after the July 7, 2016, attack.
The decision appears to conclude the investigation, which began shortly after gunman Micah Johnson fatally shot the officers.
Johnson later was killed by a robot carrying explosives -- a first for any U.S. law enforcement agency.
Ballistic reports, transcripts of police negotiations with Johnson, and other evidence has been withheld.
Johnson killed four Dallas police officers and a Dallas Area Rapid Transit officer.
