ATTACK. THANKS FOR JOINING US. I'M BLAKE HANSON. WE WANT TO UPDATE OUR TOP STORY. NOW. WE'RE LEARNING MORE ABOUT THE SUSPECT IN LAST NIGHT'S SHOOTING THAT KILLED ONE DALLAS POLICE OFFICER AND WOUNDED TWO OTHERS. THE FALLEN OFFICER, DARREN BERKS, WAS SHOT IN HIS PATROL CAR LAST NIGHT WHILE PARKED OUTSIDE OF A COMMUNITY CENTER IN OAK CLIFF. THEY SAY THE SUSPECT, COREY COB, WAS LOOKING TO MURDER AN OFFICER AND ALLUDED TO PLANS ON SOCIAL MEDIA. THE POLICE CHIEF CALLED THE KILLING AN EXECUTION. RESPONDING OFFICERS EXCHANGED GUNFIRE WITH THE SHOOTER AND TWO OF THE OFFICERS WERE WOUNDED. ONE OF THEM IS OUT OF THE HOSPITAL, THE OTHER STILL RECOVERING IN A HOSPITAL. FOX FOUR'S SEAN RAB FOLLOWING THOSE DEVELOPMENTS, HE JOINS US FROM THE NEWSROOM WITH THE VERY LATEST. SEAN. YEAH. AND SOME OF WHAT THE CHIEF WAS TALKING ABOUT AS IT RELATES TO COREY COBB. WE LEARNED THAT TODAY THROUGH HIS SOCIAL MEDIA. NEED TO UPDATE YOU ABOUT THIS MAN WHO SHOT THREE OFFICERS, KILLING 46 YEAR OLD DARREN BERKS. HE AGAIN IS IDENTIFIED AS COREY COBB, A 30 YEAR OLD MAN. THIS BOOKING PHOTO IS FROM 2017. ARREST FOR TRAFFIC VIOLATIONS, FAILURE TO ID, GIVING A FALSE NAME. WE COULD FIND NO RECORD OF VIOLENT ACTS BEFORE NOW. COBB, ACCORDING TO HIS SOCIAL MEDIA, IDENTIFIES AS A MOORISH AMERICAN NATIONAL. THAT'S A POPULATION OF THE PEOPLE THAT CONSIDERS THEMSELVES TO BE SOVEREIGN AND IMMUNE FROM U.S. LAWS. NOW, COBB POSTED VIDEOS AND THE CHIEF TALKED ABOUT THIS OF HIS APPROACHING UNDERCOVER OFFICERS TALKING TO THEM, QUESTIONING THEM AT TIMES ABOUT WHAT THEY'RE DOING, AND WHY THEY'RE IN CERTAIN PLACES.
