Approximately six shots can be heard in the recording, followed by a pause, then four more. The man who made the recording came forward, through his lawyer, has has reportedly been interviewed by the FBI.
Glide, the maker of a video messaging app that simultaneously records and streams live chats, confirmed the date, time and approximate location at which the recording was made.
"A Glide user living nearby (whose identity is being protected) was simply using the Glide app on their smartphone exactly as it was designed -- to instantly communicate with a friend through our real-time video texting service," Glide said in a statement. "Simultaneously, they also captured audio in the background of the gunshots allegedly fired at Michael Brown."
"Because Glide is the only messaging application using streaming video technology, each message is simultaneously recorded and transmitted, so the exact time can be verified to the second," the statement continued. "In this case, the video in question was created at 12:02:14 PM CDT on Saturday, August 9th."
Federal officials haven't confirmed they have this specific recording, but have said they are collecting audio and video of the incident as part of their ongoing investigation.
The pause in gunfire may corroborate witnesses' story that Wilson fired deliberately at an unarmed Brown. But it could also back up Wilson's account that he only shot to kill Brown after the teen charged at him.
Autopsies show Brown was hit by at least six bullets. Four shots to his arm and side were survivable, but the last, which struck him at the top of his head, was likely immediately fatal.
