DALLAS – Federal law enforcement officials believe Micah Johnson was the only sniper in the Dallas ambush, according to law enforcement officials briefed by the Dallas police.
Earlier in the morning, Dallas officials released the name of the gunman who killed five police officers and wounded seven other people and said they used a bomb robot to kill him.
The dead gunman was Micah X. Johnson, a 25-year-old resident of Dallas, law enforcement sources familiar with the investigaton told CNN.
Johnson apparently did not have a criminal history or any ties to terror groups, a law enforcement official said.
“We cornered one suspect and we tried to negotiate for several hours,” Dallas Police Chief David Brown said during a Friday morning news conference, but “negotiations broke down” and turned into “an exchange of gunfire with the suspect.”
A hostage negotiator talked with Johnson at length before police sent in the robot with explosives and killed him at about 2:30 a.m., Brown said.
“The suspect said we will eventually find the IEDs,” Brown said, a reference to explosives. “He wanted to kill officers. And he expressed killing white people, killing white officers, he expressed anger for Black Lives Matter.”
“We saw no other option than to use our bomb robot and place a device on its extension to detonate where the suspect was,” Brown said, adding that, “other options would have exposed our officers to grave danger.”
Five police officers were killed and seven others were injured in the ambush, which began during a protest over police violence Thursday night, officials have said. It was the deadliest single incident for U.S. law enforcement since September 11, 2001. Two civilians also were injured in the shootings, the Dallas mayor's office said.
The deadly gunfire erupted in Dallas as videos showing two African-American men shot by police in Louisiana and Minnesota spurred protests and debate over police use of force across the country.
Brown told reporters it's too soon to speculate on the suspect's motives, and it's unclear whether more suspects are on the loose.
"We're hurting. Our profession is hurting. There are no words to describe the atrocity that happened in our city," he said. "All I know is that this must stop -- this divisiveness between our police and our citizens."
