Attorney: New audio reveals pause in gunfire when Michael Brown was shot

(CNN) -- Could a newly released audio provide more clues on what led up to Michael Brown's shooting death?

The FBI has questioned a man who says he recorded audio of gunfire at the time Brown was shot by Ferguson, Missouri, police on August 9, the man's attorney told CNN.

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.

New audio of Michael Brown shooting?

"I was very concerned about that pause ... because it's not just the number of gunshots, it's how they're fired," the man's attorney, Lopa Blumenthal, told CNN's Don Lemon. "And that has a huge relevance on how this case might finally end up." What could audio of shooting reveal? The funeral of Michael Brown The funeral of Michael Brown

The man, who asked that his identity not be revealed, lives near the site of the shooting and was close enough to have heard the gunshots, his attorney said.

He was speaking to a friend on a video chat service and happened to be recording the conversation at the same time Brown was shot, Blumenthal said.

A further complication to understanding the audio, which appears to record 10 shots is that unconfirmed reports indicate there were 12, not 10, bullet casings found at the scene. This does make it appear that the cop, Darren Wilson, who previous to his hire at Ferguson worked at a police department that had such bad race relations with the community that it was DISSOLVED, emptied his weapon into Michael Brown.
