He also served in Seagoville, Texas, and is listed as a Carpentry and Masonry Specialist.
A senior US law enforcement official familiar with the investigation identified the deceased suspect as Micah Xavier Johnson.
The motives for Johnson's attack still aren't totally clear - he's quoted as saying he was "upset about Black Lives Matter" and that he "wanted to kill white people, especially white officers." clear enough, it would seem, but he must have felt awfully strongly to plan such an elaborate attack.
"We saw no other option but to use our bomb robot and place a device on its extension for it to detonate where the suspect was", Brown said.
Though bomb squad robots - officially "explosive ordnance disposal" or EOD robots - are nearly commonplace in today's tech-savvy law enforcement agencies, their existence is still relatively unknown beyond police and military circles.
Before dying, the police chief said, the suspect also stated that he acted alone and was not affiliated with any groups, Brown said.
A Twitter account describing itself as representing the Black Lives Matter movement sent the message: "Black Lives Matter advocates dignity, justice and freedom".
"Too many people who aren't criminals, but have a big mouth, created situations like we had last night", Patrick said, his voice rising. "But we're not satisfied that we've exhausted every lead", he said.
The shootings began shortly before 9 p.m. Thursday when, police say, an uncertain number of snipers shot and killed five police officers, wounded seven more and injured two civilians.
In suburban St. Louis, a motorist shot an officer at least once as the officer walked back to his vehicle during a traffic stop, police said.
"There's a huge difference between somebody sending a threat and somebody actually shooting a police officer", Haberfeld said.
"Please join me in applauding these courageous men and women who do this job under great scrutiny, under great vulnerability". He was the first officer killed in the line of duty since Dallas Area Rapid Transit formed a police department in 1989, DART said on its website.
Police Chief David Brown blamed "snipers", but it was unclear how many shooters were involved in Thursday's attack.
During lengthy negotiations with police, the gunman said "the end is coming", Brown told reporters. Dallas Mayor Mike Rawlings said one of the wounded officers had a bullet go through his leg as three members of his squad were fatally shot around him. "It's what makes us who we are as Americans".
Area groups against police brutality are condemning Thursday's ambush in Dallas and are working on strategies to bring the divided country together. In a statement issued through her lawyer, she said "responding to violence with violence is not the answer", adding: "Our hearts break for the families of the officers". Three suspects were eventually arrested and a fourth was killed during a standoff.
President Barack Obama commented about the incident earlier Friday morning from Warsaw, Poland - where he's meeting with leaders of the European Union and attending a North Atlantic Treaty Organisation summit.
