Antonio Perkins, 28, was found fatally shot in the North Lawndale neighborhood Wednesday night, and a video circulating online claims to show the moments just before he was shot.
About 8:45 p.m., Perkins was found facedown with gunshot wounds to the neck and head in a vacant lot in the 1600 block of South Drake, according to Chicago Police and the Cook County medical examiner's office.
He was taken to Mount Sinai Hospital, where he was pronounced dead at 9:07 p.m., authorities said. He lived in the 3500 block of West 12th Place.
The video, posted by the New York-based website MediaTakeOut.com, claims that Perkins, also known as Cicero Yayo, was taking a Facebook Live video of himself partying with friends. It then shows a car go past the scene once and then return.
The video clearly contains the sound of gunshots and then the camera falls to the ground and goes black, though people can be heard in the background screaming and calling for an ambulance.
The video had been viewed more than 263,000 times and shared nearly 7,000 times on Facebook as of Thursday morning.
This isn't the first time Facebook Live has streamed a shooting as it happened.
Two months ago, Brian Fields was in West Englewood when bullets started flying. Fields was critically-wounded and another man was seen returning fire.
In Perkins' case the shooting occurred about six minutes into his live broadcast.
It's unclear if his presence on Facebook allowed the shooter to find him.
Police said arguments and taunting on social media have helped fuel a spike in gang violence. In fact, police have a social media unit that monitors online conflicts.
