This is a developing story.

At least four police officers were killed and several others injured in shootings at the end of a Black Lives Matter protest in downtown Dallas on Thursday evening (July 7). As of 12:30am local time Friday, police had in custody at least four people of interest and were negotiating with a suspect who was in a parking garage near the shootout scene. Dallas police chief David Brown said the suspect “has told our negotiators that the end is coming and he’s going to hurt and kill more of us, meaning law enforcement, and that there are bombs all over the place in this garage and in downtown.”

The first shooters appear to have been positioned above the crowd when they opened fire around 8:45pm local time, the AP reported. Multiple rounds of shots could be heard on one video shot and posted on Facebook, apparently by a protest attendee.

Brown initially said that snipers shot at 10 officers. Local reports put the number at 11.

The shooting occurred just blocks from The Sixth Floor Museum at Dealey Plaza, on the site where Lee Harvey Oswald shot US president John F. Kennedy in 1963. The hurt officers were taken to two nearby hospitals.

The Dallas police department circulated a photo of a possible suspect.

That person of interest turned himself in, Brown said. Police also had in custody a female who was in the area of the garage where the suspected shooter was negotiating with police, along with two suspects with camouflage bags who were stopped in their Mercedes in the nearby neighborhood of Oak Cliff after a chase.

Brown said police are assuming that the person shooting at them in the garage, along with the people who were apprehended, were working together.

“We still don’t have a complete comfort level that we have all the suspects,” Brown said, promising a “very, very rigorous investigation and search of downtown [Dallas].”

The suspects were being interrogated to determine their motivation, including whether they were complicit with the organizers of march, he added.

Next Generation Action Network, the local group that organized the rally, posted a statement on Facebook saying its intentions were peaceful and that it did not condone violence.

The dead included three members of the Dallas police department, as well as a Dallas Area Rapid Transit officer.

Dallas mayor Mike Rawlings said he has “heard from both the White House and the governor’s office extending their help.”
