The 28-year-old man, Antonio Perkins, was shot toward the north end of the 1600 block of South Drake Avenue around 8:45 p.m., authorities said.
The video appears to show Perkins recording himself and talking before someone opened fire and Perkins collapsed. He is shown with a group in front of a home when at least six shots are heard and the phone appears to tumble through bloody grass before going black.
The video looks like it was shot at dusk, around the time Perkins was killed. It was posted live on Facebook on Wednesday night. READ MORE OF THIS STORY
