The man who shot 12 police officers, killing five, at a Black Lives Matter protest in downtown Dallas on Thursday night has been named as Micah Xavier Johnson, a 25-year-old Army reservist with no criminal history or ties to terror groups.

Johnson, from Mesquite, Texas, a 20 minute drive from Dallas, reportedly told law enforcement that he was a veteran, and claimed to have acted alone, countering initial reports that as many as four gunmen were involved in the massacre.

'The suspect said he was upset about Black Lives Matter. He said he was upset about the recent police shootings of black suspects. He said he was upset at white people. The suspect stated he wanted to kill white people, especially white officers,' Dallas Police Chief David Brown revealed at a 7:30am press conference.

Around 11pm on Thursday, cops cornered Johnson at El Centro College and attempted to negotiate, but four hours later the talks failed and a robot was brought in to detonate a bomb and kill the suspect. This was after shots had rung out at a previously peaceful protest in downtown Dallas with demonstrators screaming and running for their lives as cops dropped dead one by one. 

Johnson reportedly wore body armor, which would suggest why a cop wasn't able to kill him when he confronted him in a one-on-one situation which was caught on camera. It resulted in the cop being executed. He also carried an SKS semi-automatic assault rifle and a handgun, and several rounds of ammunition, according to law enforcement sources.

A black SUV found at the scene of the shootings was listed as registered to Delphene Johnson, also of Mesquite, who is understood to be his mother. Police gathered at the address of Ms Johnson on Friday and were seen searching the property. 

The casualties include Dallas police officers Patrick Zamarripa, Michael Krol, Lorne Ahrens and Michael J. Smith, as well as DART Officer Brent Thompson.

A relative of Johnson posted these pictures of him in his Army formal attire and fatigues to Facebook in 2014. A source later told Reuters that Johnson was a member of the U.S. Army Reserve

After Johnson's name was released, his sister wrote a post on Facebook asking for 'respect for my family'

Johnson reportedly used an SKS semi-automatic rifle (similar model above) and a handgun in the shooting 

Two other suspects were taken into custody after fleeing the scene in a black Mercedes. An officer saw one of the pair hurriedly putting a camouflage bag in the back of the car before driving off 'at a high rate of speed'. A female, who was in the same area as Johnson, was also taken custody, however Chief Brown said: 'We still don't have complete comfort that we have all the suspects.'

Johnson reportedly fired from an 'elevated position', picking off officers 'ambush style,'  Chief Brown said, suggesting that the shooter had some tactical background. 'Some officers were shot in the back,' he added.

Army officials said Johnson was a soldier in the reserves and had served a tour of duty in Afghanistan. His military occupational specialty was carpentry and masonry. His service dates, as provided by the Army, were March 2009 to April 2015. The Army says Johnson deployed to Afghanistan in November 2013 and returned in July 2014. During his service, he was awarded the Army Achievement Medal.

Pictures on Facebook suggest that Johnson's father, James, was also in the military.  While he professed a hatred for white people in his last words to a hostage negotiator, it appears his step-mother was white. Donna Ferrier Johnson, a teacher for Dallas schools, proudly shared pictures of her step-son in uniform to her page before the shooting. 

Nevertheless, Johnson's activity online suggest he became interested with black militant groups. On Facebook, he identified himself as a black nationalist, and his profile picture shows him wearing a dashiki and holding a clenched first in the air like a Black Panther.

He also liked pages for several pages related to the Nation of Islam, the Black Riders Liberation Party, the New Black Panther Party and the African american Defense League. 

Johnson also used to attend a gym called Academy of Combat Warrior Acts, which teaches weapons classes in addition to the traditional martial arts selection, according to the Daily Beast. 

Gym CEO Justin Everman spoke out to the Daily Beast, saying many of the gym's members are police officers and 'we have completely no affiliation with [Johnson] whatsoever.'

A woman who lived on the same street in Mesquite, Texas, said that Johnson told them that he had 'lots of guns' and that she thought he had served overseas.

When his rifles were stolen eight months ago he became 'very upset', she said.

The woman, who declined to give her name, said: 'About eight months ago he knocked on all the doors on the street and said that his rifles had been stolen from his home.

'He wanted to know if anyone had seen the thieves going down the alley at the back of his house. He thought it happened about 3am.

'I know he had lots of guns because that's what he told us. He seemed like a nice guy to us, he was polite. He was very upset about his guns'.

Neighbors said that Johnson lives in two-story home on a quiet suburban street, which is opposite a large field, with his mother and had been there for years.

Officers from the Bureau of Alcohol Tobacco and Firearms took evidence boxes out of the house and a police car blocked off the street.
