(RNN) - Eleven officers were shot and five have died after snipers took aim at police at a protest in Dallas Thursday, police reported.
Snipers shot the officers from elevated positions, Police Chief David Brown said. A civilian was also shot.
Police continued to negotiate into early Friday morning with a suspect hiding in a garage who police described as not cooperative. Officers said they exchanged gunfire with the suspect. Local media reports he shot himself and is dead. Dallas police have not confirmed the suspect's death.
"We're leaving every motive on the table of how this happened and why it happened," said Brown.
At least three people were in custody: a female detained near the garage where the standoff was underway and two occupants of a black Mercedes seen speeding from the area. One of the occupants reportedly threw a camouflaged bag into the car before taking off. Officers followed the vehicle and made a traffic stop.
A man wearing a camouflaged shirt and carrying a large gun originally identified by police as a person of interest turned himself in. He was later released and is not considered a suspect.
A barrage of gunfire was captured on a video posted on Twitter. Warning: The video contains strong language that some may find offensive.
Dallas Area Rapid Transit identified one of the deceased officers as Brent Thompson, 43. He was the first DART officer killed in line of duty and joined the department in 2009. The deceased officers from the Dallas Police Department have not been identified.
The Dallas protest was just one of many around the country that broke out after an officer-involved shooting in Minnesota left Philando Castile dead.
Castile's fiance shared live video Wednesday on Facebook of his final moments after he was fatally shot by a police officer who stopped them for a broken tail light.
The Minnesota Bureau of Criminal Apprehension identified the officers involved as Officer Jeronimo Yanez and Officer Joseph Kauser, both who have been with the St. Anthony Police Department for four years. It identified Yanez as the officer who fired on Castile.
Diamond Reynolds' video was removed from Facebook, but was shared more than 50,000 times and posted on YouTube. She said Thursday that she never saw police try to provide aid to Philando Castile after he was shot, something Minnesota Gov. Mark Dayton called "absolutely appalling." The governor expressed outrage that she was cuffed and taken to the police station in the same cruiser as her 4-year-old daughter.
Dayton asked the Justice Department to investigate the fatal shooting.
"He was never a bad man," Reynolds said of her fiance. "He never did anything to hurt anyone; he was the quietest, most laid-back person you would ever meet. He was loving. So even for the police to take him away, nothing within his body language said intimidation, nothing within his body said, 'Shoot me.' Nothing within his body language said, 'Kill me, I want to be dead.'"
Reynold's 4-year-old daughter was in the backseat of the car when the officer opened fire on Castile, 32.
"Please, officer, don't tell me that you just did this to him," said Reynolds as she recorded on her cell phone. "You shot four bullets into him, sir. He was just getting his license and registration, sir."
Castile's family members told the Minneapolis Star-Tribune that he died at 9:37 p.m. CT Wednesday, minutes after arriving at the hospital. His mother said Thursday she believes her son, who is black, was racially profiled.
"There are those that sit up and say there is no more … profiling, they're still saying there is no profiling, but there is," the victim's mother, Valerie Castile said. "We're being hunted every day."
Reynolds described the officer as Asian. Police said he had been placed on paid administrative leave.
Reynolds began recording the video while Castile lay motionless in a blood-splattered shirt as the officer held him at gunpoint through the driver's side window.
"We got pulled over for a busted tail light," she said. "He's licensed to carry. He was trying to get out his ID in his wallet in his pocket, and he let the officer know that he had a firearm and he was reaching for his wallet. And the officer just shot him in his arm."
The officer, who has not been identified, can be heard in the video screaming that he "told him not to reach for it." The officer is heard telling Reynolds, "Keep your hands where they are."
Later in the video, Reynolds exits the vehicle at the request of the officers as she prays for her boyfriend's life and asks about her daughter. Reynolds and her daughter were not injured.
Reynolds can be heard on the video shouting, "Oh my God, please don’t tell me he’s dead. Please don’t tell me my boyfriend just went like that."
Reynolds continued live-streaming after she and her daughter were placed in the police squad car.
President Barack Obama addressed the shooting from the NATO summit in Poland, saying that there is "no contradiction between supporting law enforcement ... and also saying that there are problems in our criminal justice system ... that have to be rooted out."
"The data shows black folks are more vulnerable to these kinds of incidents. It isn't a matter of us comparing the value of lives. This is recognizing there is a particular burden that is being placed on a group of our fellow citizens," he said.
Overnight, as word of Castile's death spread, a large group of people gathered at the scene of the shooting and then moved to the governor's mansion in nearby St. Paul. The Associated Press reported around 200 people chanted and demanded action from Gov. Mark Dayton.
The protesters chanted, "No justice, no sleep. Mark Dayton, do you care?"
In a one-minute press conference, St. Anthony Police Interim Chief Sgt.Jon Mangseth, told reporters he was not aware of the Facebook video or its content. Mangseth did not answer reporters' questions.
“[We haven’t had an] officer-involved shooting in, you know, 30 years or more. I’d have to go back in the history books, to tell you the truth,” Mangseth said. He said the officer who fired the shots has been placed on administrative leave. The Minnesota Bureau of Criminal Apprehension is investigating the shooting.
The shooting of Castile in Falcon Heights, a St. Paul suburb, came one day after the fatal officer-involved shooting of Alton Sterling in Baton Rouge, LA, which was captured on video.
