Heuermann has entered the courtroom in a gray suit. He looked down as he entered, only looking up at his attorneys.
A moment of levity occurred after a loud tapping noise was heard in the courtroom. Judge Mazzei deadpanned: "What the hell is that?"
Laughing ensued in the overflow courtroom.
The source of the noise was unclear.
