(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.
“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.”
