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.”
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.
