Dallas police on Friday confirmed the gunman who killed five officers in a shooting rampage was a 25-year-old named Micah Johnson, an Army veteran from Texas with no criminal history.
"The deceased suspect has been identified as Micah Johnson," the Dallas Police Department said in a statement. "During the search of the suspect's home, detectives found bomb-making materials, ballistic vests, rifles, ammunition, and a personal journal of combat tactics."
Johnson acted alone, the
New York Times is reporting.
Johnson, who was subsequently killed by police after a lengthy standoff in a parking garage, told law enforcement negotiators that he alone was responsible for the massacre.
Dallas Police originally believed there to be at least two snipers who were trying to triangulate on the exposed officers.
WFAA reported that a rifle and a handgun were recovered from the scene where police used a robot-delivered bomb to kill Johnson. The
Daily Mail reported the rifle to be an SKS semi-automatic rifle.
WFAA also reported that Johnson was wearing heavy body armor and had multiple rounds of ammunition.
The Times reported that law enforcement officials would not disclose whether they believe the three suspects arrested and Johnson, of Mesquite, Texas, were the only ones involved, nor would they identify the three in custody.
A profile of Johnson has been trickling out over the course of Friday.
According to the Associated Press, Johnson joined the Army Reserve in March 2009. The
Washington Post reported Johnson, who worked in carpentry and masonry, served one tour of duty in Afghanistan in 2013, and he was a member of the Individual Ready Reserves at the time of his death.
Johnson, who lived outside of Dallas, just turned 25 on July 2. His Facebook page has been taken down, but not before screen grabs of his social media photos
were published on Heavy.com.
Johnson reportedly has no known criminal history or links to terror groups, according to several news outlets. However,
TMZ reported Johnson was affiliated with several Black Panther groups and subscribed to a Facebook group called "The Black Matrix."
A black SUV was found at the scene registered to Delphene Johnson, purportedly Micah Johnson's mother, according to Facebook posts and public records,
NBC Dallas-Fort Worth reported.
His sister, Nicole Johnson, posted on Facebook on Friday after his name was made public, Heavy.com reported.
"I keep saying its not true…my eyes hurt from crying. Y him??? And why was he downtown smh. Please out of respect for my family. If you following the news and know whats going on, I'm not talking to anyone and please keep your comments thoughts respectful," she wrote. "The news will say what they think but those that knew him know this wasn't like him. Only close family can call me. This is the biggest loss we've had."
A neighbor of Johnson's, Wayne Bynoe, said there are police cars outside Johnson's home. Bynoe told CNN that Johnson lived with his mother and "keeps to himself,"
according to KTXS.
