ST. LOUIS -- Seven shots. A three-second pause. Four more shots.
An audio file obtained by the St. Louis Post-Dispatch on Tuesday is believed to have captured the shooting of Michael Brown Jr.
If authenticated, it would be the first recording of the incident to have surfaced since Brown's death on Aug. 9.
Lawyer Lopa Blumenthal said her client, who lives in the apartment complex near where Brown was killed, captured the shooting while recording a video text message to a friend.
Blumenthal said the man who made the recording did not want to be named. She said he came forward reluctantly and feared for his safety.
The FBI interviewed him for about an hour and a half on Monday, she said.
A private autopsy showed Brown was shot six times, but did not reveal the number of times Ferguson Police Officer Darren Wilson fired his weapon.
The shooting has sparked nightly demonstrations and attracted world wide media attention.
Blumenthal said sympathizers to both Brown and Wilson have contacted her saying that the three second pause bolsters their cases.
But Blumenthal said she thought the recording was important.
"There was a pause," she said, "and to me a pause means time to think and contemplate."
Blumenthal would not reveal her client's name or the exact location of his residence, except to say it was in the Canfield Green apartment complex, near the scene of the shooting.
Nor would she give out the name of the person who received the video. But she said she was certain the recording is authentic.
"I'm 100 percent positive this is accurate," she said. "He is not doing this for the publicity. He has no motivation to lie."
