Chicago police are investigating a video posted to Facebook that appears to show the slaying of a West Side man who was shot in the Lawndale neighborhood Wednesday evening.



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.



Police said Thursday they are aware of the video and are reviewing it.



The video starts with a woman describing what the group was doing on the street. People constantly refer to the man "Tony." He takes the phone back three minutes in.



"Mom, I'm hot," he says repeatedly at about 3:30. A stroller can be seen behind him at about 3:50. About 5 minutes in, a small child's voice is heard.



Everything is quiet until 5:50, when the man looks to his right, starts to say, "Boy, stop playin' " and shots go off. The camera falls, then a few more shots.



People start screaming.



"Oh my God."



"Call the police! Hurry up!"



"Where he hit at?"



"Oh my God."



"Let me call you back."



"Tony, you good Tony. Tony, you good Tony. You good Tony."



"Put pressure on that (expletive), you gotta put pressure on that, man."



"You good Tony, you good Tony. Tony. Tony! Tony!"



A car horn honks.



"He bleeding out his mouth and his nose right now."



The chaos continues for a few minutes while the screen is black.



"He's choking on his blood," a woman wails.



A woman says Tony's been shot on "Drake and 16th."



Someone asks them to step back a few seconds after sirens can be heard.



"Tony, c'mon Tony."



"Roll him over."



"No, he's gon' choke on his blood if we roll him over."



Officers can be heard asking people to move back.



"Flip him over and get him out of here," someone close to the phone says.



The sounds of screaming are more distant at this point.



Authorities said Perkins was taken to Mount Sinai Hospital, where he was pronounced dead at 9:07 p.m.
