A company whose video chat service apparently captured audio of Michael Brown 's shooting said Thursday the recording was created at the time the Missouri teenager was killed this month . The revelation from Glide appears to bolster a man 's claim that he inadvertently recorded audio of gunfire at the time a police officer shot and killed the 18-year-old Brown in the St. Louis suburb of Ferguson on August 9 . The video was created at 12:02:14 p.m. that day , Glide said . Brown , who was unarmed , was shot by Ferguson police officer Darren Wilson shortly after noon . `` A Glide user living nearby 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 . Simultaneously , they also captured audio in the background of the gunshots allegedly fired at Michael Brown , '' the company said . The sounds could be a piece in the larger puzzle of what happened during the shooting , which spurred days of protests in the city of 21,000 . Police have said Brown was trying to grab the officer 's gun . Witnesses say the teen was holding his hands in the air when he was fatally shot . Investigators are determining whether to accuse the officer of wrongdoing ; no charges have been filed . The FBI obtained the audio and interviewed the man who made the recording , said Lopa Blumenthal , a lawyer for that individual . The man , who asked that his identity not be revealed , lives near the site of the Brown shooting and happened to be using the application at the same time Brown was shot , Blumenthal said . In the recording , a quick series of shots can be heard , followed by a pause and then another quick succession of shots . Forensic audio expert Paul Ginsberg analyzed the recording and said he detected at least 10 gunshots -- a cluster of six , followed by four . The significance of the pause . Witnesses and a friend of Wilson have given conflicting accounts of what led to Brown 's death , and the pause could be key in the investigation . But it 's difficult to prove from the audio why the pause took place or whose narrative it supports . Ferguson police have alleged that Brown robbed a convenience store shortly before the shooting , and that he and a friend , Dorian Johnson , were walking down a street when Wilson approached them in a police car . Police say Wilson stopped Brown not because of the theft , but because Brown and a friend were blocking traffic . Wilson tried to exit his vehicle but Brown pushed him back into the car , according to a preliminary investigation , St. Louis County Police Chief Jon Belmar said . Read the police reports . Brown assaulted the officer while Wilson was in the car , and a shot was fired inside the police car during a struggle over the officer 's gun , Belmar said . Johnson disputes that , saying Wilson -- while sitting in the car -- started the scuffle by grabbing Brown by the neck , and that Brown tried to pull away . Johnson also said that there was no struggle for the gun , but rather that Wilson drew the weapon and shot Brown once at the car . Johnson said Wilson shot Brown again as the teen ran away . According to Johnson , Brown was struck in the back and then turned around and put his arms up as the officer kept shooting . But a woman who identified herself as a friend of Wilson called in to a St. Louis radio show with what she said was the officer 's version of events . The caller , who identified herself only as `` Josie , '' said Brown -- after going away from the vehicle following the first shot -- turned around , taunted the officer and charged at him . Her account matches what Wilson has told investigators , a source with detailed knowledge of the investigation told CNN . An autopsy showed Brown had six gunshot wounds . Attorney Chris Chestnut told CNN this week he was surprised by the gap in shots . `` It 's the pause that gives most concern in a police shooting , especially with an unarmed victim , because at this point Mr. Brown is defenseless -- he has no weapon , '' said Chestnut , who represented the family of Jonathan Ferrell . Like Brown , Ferrell was an unarmed African-American man who was shot and killed by a white police officer . That incident occurred in North Carolina . But if the gunfire heard on the audio is from the Brown incident , the pause does n't automatically suggest wrongful intent by the officer . `` To be fair , there could be other explanations for that pause , '' said attorney Van Jones , co-host of CNN 's `` Crossfire . '' `` Maybe the officer will say , 'Well , I fired and he kept advancing , so I fired again . ' `` Complete coverage .
