A smartphone application company has confirmed that their app was used to record audio during Michael Brown's shooting.

Brown, 18, was fatally shot by a white police office in the Missouri suburb of Ferguson on Aug. 9. Police officer Darren Wilson, 28, claims that he shot the unarmed African-American teen because Brown reached for his gun, however several eye witnesses say that Brown was shot execution style while he was trying to surrender.

While investigators look into this case and decide whether to file charges against Wilson, the audio recording popped up as a new piece of evidence. In the 12 second recording, 10 gun shots can be heard.

Glide, the company whose video chat service allegedly captured audio of the shooting, announced Thursday that the recording was created in the neighborhood where the teenager was killed and during the same time of that the officer opened fire It was recorded inadvertently by a Ferguson man who was using the video-texting application on his cell phone to send a message to a friend.

According to Glide the recording was created at 12:02 p.m. CT on Saturday Aug. 9, which is precisely the time officals say Brown was shot.

"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. Simultaneously, they also captured audio in the background of the gunshots allegedly fired at Michael Brown," Glide said in a statement released on Thursday. "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 unidentified man's lawyer, Lopa Blumenthal, said she released the recording to the FBI after he shared it with her, reports MSNBC.

Forensic audio expert Paul Ginsberg said he detected at least 10 gunshots altogether, starting with a cluster of six and then four more followed by a pause, reports CNN.
