Dallas Police Chief David Brown says a shooting attack that left five police officers dead was "well planned."
Speaking at an interfaith prayer vigil in downtown Dallas on Friday, Brown called the shootings the previous night a "well-thought-out evil tragedy," saying his force "won't rest until we bring everyone involved to justice."
Christian, Jewish and Muslim faiths were represented at the vigil that was attended by hundreds.
Seven other police officers were wounded in the shooting during a protest over the killing of black men by white police officers in Louisiana and Minnesota. Two civilians were also hurt, but Dallas Mayor Mike Rawlings has said no one suffered life-threatening injuries.
Brown has blamed "snipers," but it is unclear how many shooters were involved in Thursday's attack.
Suspect's Home Searched
Authorities have apparently finished an initial search of the home of a suspect in the deadly attack on Dallas police officers.
Agents in Bureau of Alcohol, Tobacco, Firearms and Explosives vests on Friday carried several bags of unknown materials from 25-year-old Micah Johnson's home in the Dallas suburb of Mesquite.
Authorities stopped blocking off the street just before noon. No one answered a knock on the door at the home.
A Texas law enforcement official identified Johnson to The Associated Press as a suspect who was killed by police with a robot-delivered bomb. He spoke on the condition of anonymity because he wasn't authorized to release the information.
The Army says Johnson served in the Army Reserve and did one tour of duty in Afghanistan.
Friend of Suspect Speaks Out
A friend of a man suspected in the deadly attack on Dallas police officers says his friend was educated and "wasn't really political."
Israel Cooper says 25-year-old Micah Xavier Johnson "wasn't one of those, 'ah man, white cops, blacks cops, you know'" kind of people.
A Texas law enforcement official identified Johnson to The Associated Press as a suspect who was killed by police with a robot-delivered bomb. He spoke on the condition of anonymity because he wasn't authorized to release the information.
Cooper says he played basketball with Johnson dozens of times near Johnson's suburban Dallas house. He says the last time he saw Johnson was a about week ago and that Johnson was "cool" with a "good vibe."
Cooper says when he heard Johnson was a suspect he couldn't believe it because Johnson wasn't "a violent or rough dude."
