There's a little disconnect here - the eyewitnesses are saying the shooter didn't say anything, but Patti Ann Brown just reported that he was spewing "obscenities".

The witness from Germany said he was unsure when they asked if the guy said anything...

The guy said he didn't hear anything but the shots. When a person's in shock (and even if he seems calm, he's been through major trauma), he may not remember everything immediately. The mind does crazy things when it's under stress.
