Cops: 3 Suspects in Custody After Dallas Shootings

Three suspects are now in custody after the killing of five police officers during a protest Thursday night, and a fourth suspect is still exchanging fire with police, Dallas Police Chief David Brown says. The chief says the suspect has told negotiators he plans to hurt more officers and has planted bombs all over the area, the AP reports. He says the suspects in custody include a woman who was arrested in the same parking garage where the standoff continues. Another two suspects were taken into custody after police stopped their vehicle. Brown told reporters early Friday that the officers were killed by shooters with rifles who were working together and that it's not clear whether there are more suspects out there, the Dallas Morning News reports. In other developments:

• A "person of interest" whose photo was tweeted by Dallas police turned himself in and was released after it was determined he had no connection to the shootings, the Guardian reports.
• Police announced around 2am that another officer had died from his injuries, bringing the death toll to five, with another six officers injured.

• Clay Jenkins, Dallas County's chief executive, says the shooters' motives are unknown, apart from the fact that they fired on police, the New York Times reports.
• WFAA rounds up some videos posted on social media after the shootings, including one that shows marchers panicking as shots ring out.
• Rev. Dominique Alexander, president of the Next Generation Action Network, tells the Morning News that the protest was a call for justice after recent police shootings, but it was not organized by the Black Lives Matter movement. He says he saw a photographer shot in the leg in front of him and was told that at least one of the shooters was white.
• A Morning News op-ed calls the shootings terrorism that shattered a peaceful march. It was a "well planned and barbaric attack on that peace. In purposely murdering police officers, these gunmen did not further any cause or make any kind of statement that civilized people can understand. They opened fire, literally, on human decency."
• Reuters reports that other protests around the country remained peaceful, with crowds gathering in cities such as Chicago, New York, and St. Paul, Minn., to protest the police shootings of Alton Sterling and Philando Castile.
