Dallas police shootings: Suspect killed was Army vet, lone shooter

A Texas law enforcement official identified the slain suspect as Micah Johnson, 25. Then police exchanged gunfire and negotiated with a suspect for hours at a parking garage in downtown Dallas.

Yes. Brown said whoever organized the ambush had probably known the route the protest march would take and had "triangulated" their targets from "an elevated position". He also said it is important for people not to make generalizations about law enforcement.

Gunfire targeting police officers interrupted a peaceful demonstration in downtown Dallas, where protesters were rallying against the shooting deaths of two black men by police in Louisiana and Minnesota this week.

The Army says Johnson was a private first class and his home of record is Mesquite, Texas.

Although Brown said the suspect said he acted alone, it remains unclear if that was the case. A Black Lives Matter march was underway through the streets of downtown Dallas when the shots rang out around 8:45 p.m. PHOTOS: Shots fired during downtown Dallas protestHundreds of protesters scrambled and ran for safety.

Kenyon Police Chief Lee Sjolander said this week's violence is disheartening. Authorities initially said three suspects were in custody and a fourth dead.

"Other options would have exposed our officers to grave danger", he said. He would not say how authorities believe others in custody are connected to the shooting.

Three of the injured officers were in critical condition undergoing surgery Friday morning.

In the hours after what appears to be the most deadly attack on police since September 11, everyday habits are suspended. There were no immediate details on the suspect's middle name or hometown. Mayor Rawlings tells MSNBC that the suspects were being "pretty tight-lipped".

"Everyone just started running", Devante Odom, 21, told The Dallas Morning News. "That's just stupid, and even worse than that, that would be wrong and reprehensible", he said.

The police chief recounted how negotiations with the suspect, who has so far only been identified as male, broke down over time. Police earlier said only that the gunman had been "neutralized". Two civilians also were wounded.

Castile, a school food services worker, was shot in Falcon Heights, outside Minneapolis, when a police officer pulled him over because of a broken taillight, said Reynolds, who was in the vehicle with him. But how we handle it can do a lot of things. The mayor and police chief were seen arriving there. Brown was also shot by a police officer.

Essentially, if a standoff suspect knows the police can kill them with impunity and little risk to themselves, the suspect knows they have little power in negotiating, which could lead them to escalate the situation.

It was the deadliest day for U.S. law enforcement since the 2001 terrorist attacks. He told reporters that anyone involved "in these senseless murders will be held fully accountable, justice will be done". That, too, was captured on a cellphone video. Warning: Video includes profanity.

"Dallas officers are hurting". Johnson was killed with a robotic that police had attached an explosive device to and detonated. Federal authorities also halted commercial air traffic for the area as police helicopters hovered over the scene.

Because the shootings took place while the streets were filled with protesters, there were many witnesses. It was one of many protests around the country. Taylor, who jumped on top of her sons to protect them, was shot in the leg and is expected to recover.
