(AP Photo/Eric Gay) (Newser) – Details continue to emerge regarding Thursday night's police shooting in Dallas, with Mayor Mike Rawlings calling it a "heartbreaking morning," per the Dallas Morning News. Of note: At least 14 people in total were shot at the police brutality protest, Rawlings confirmed, per WFAA: The death toll remains at five—four Dallas cops and one Dallas Area Rapid Transit officer—with at least seven officers and two civilians injured. The one suspect reported dead after a standoff with police didn't die by a self-inflicted gunshot wound, as reported earlier, but rather was killed by a bomb-detonating robot sent into an El Centro College parking garage by police, ABC News reports. After hours of police negotiations with the suspect and gunfire exchange, cops "saw no other option but to use our bomb robot … for it to detonate where the suspect was," Dallas Police Chief David Brown said at a Friday morning press conference. Before he died, that suspect told cops he was acting alone and not connected to any group, as well as that he "wanted to kill officers" and "expressed anger for Black Lives Matter," Brown said, adding, "None of that makes sense." As for other suspects: A female was taken into custody from the same parking garage where the other suspect was killed, per KDFW, and Brown says two other suspects were also detained after they were seen speeding away from downtown in a car with camo bags. Brown said he's still not sure all suspects have been brought in, and officials are remaining tight-lipped on the ones they're questioning. "Now is not the right time," Rawlings said about revealing further details.
