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 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 US Army Veteran, and claimed to have acted alone, countering 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 an 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.
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.
All five cops killed were men and two have been identified so far: 43-year-old DART Officer Brent Thompson and young young father Patrick Zamarripa.
