We've had crews covering this tragedy for more than 24 hours. Matt Howerton is outside Dallas police headquarters. But we start tonight with the emotional tributes Joan Pur is at the site of the vigil for Officer Burkes Joby Sunday. There were two vigils being held tonight. Four Officer Burkes put on by his fraternity brothers. That's how a lot of the news of his passing got passed around and is being felt very hard today. They came here to say what many already knew that Darren Burks was one of a kind, this is a witness of who he was. The Dallas officer just feet from here was shot and killed while in his car while on duty. The uniform made him the final hero in attendance were his fraternity brothers in broiled purple, his brothers and sisters in blue and so many others who would color Darren Burkes the same way he was a shining example of how to do it the right way. Darren studied at Paul Quinn college, went on to become a teacher, worked with kids before he decided to start his career as a police officer. He never drank, he never smoked. He was high on life. There was a place for Darren at this vigil, but we wanted to make sure that we still represented his presence here, his shoes, his hat, and also someone who was practically a sister. I can't believe that this is happening is so unreal known to so many people and by so many names. Hallelujah. But they say there was only one Darren Burkes. Oh, consistent never changed. And as one speaker put it, he will be missed and not forgotten in Dallas. I'm.
