DALLAS—The suspect in the deadly attack on Dallas police officers scrawled letters in his own blood on the walls of the parking garage where officers cornered and later killed him, the police chief said Sunday.
Micah Johnson, a 25-year-old Army veteran, wrote the letters “RB” and other markings, David Brown told CNN’s “State of the Union.”
Investigators are looking through evidence from Johnson’s suburban Dallas home to try to figure out what those letters might mean, Brown said.
The chief defended the decision to kill Johnson using a robot-delivered bomb, saying negotiations went nowhere and that officers could not approach him without putting themselves in danger.
During the roughly two-hour standoff in the garage, Johnson lied to and taunted the police negotiators, Brown said.
Johnson had practiced military-style drills in his yard and trained at a private self-defense school that teaches special tactics, including “shooting on the move,” a maneuver in which an attacker fires and changes position before firing again.
He received instruction at the Academy of Combative Warrior Arts in the Dallas suburb of Richardson about two years ago, said the school’s founder and chief instructor, Justin J. Everman.
Everman’s statement was corroborated by a police report from May 8, 2015, when someone at a business a short distance away called in a report of several suspicious people in a parked SUV.
The investigating officer closed the case just minutes after arriving at a strip mall. While there, the officer spoke to Johnson, who said he “had just gotten out of a class at a nearby self-defense school.”
Johnson told the officer he was “waiting for his dad to arrive” and pick up his brother. No one else was apparently questioned.
On Friday, Dallas Mayor Mike Rawlings described Johnson as “a mobile shooter” who had written manifestos on how to “shoot and move.”
Authorities have said the gunman kept a journal of combat tactics and had amassed a personal arsenal at his home, including bomb-making materials, rifles and ammunition.
The academy website refers to one of its courses as a “tactical applications program,” or TAP.
“Reality is highly dynamic, you will be drawing your firearm, moving, shooting on the move, fixing malfunctions, etc. all under high levels of stress,” the website says. “Most people never get to train these skills as they are not typically allowed on the static gun range.”
The TAP training includes “shooting from different positions,” ‘'drawing under stress“ and ”drawing from concealment.” Everman declined to specify which classes Johnson took.
“I don’t know anything about Micah. I’m sorry. He’s gone. He’s old to us. I have thousands of people,” Everman told The Associated Press on Saturday.
