It was a signer of one letter who subsequently informed the judge that her letter was embellished that led to the discovery that Gad had, in fact, submitted several fake letters. Judge Koh said, “What I considered and what I found to be very compelling about this [the signer’s] letter, are lies that Mr. Gad put in the letter.”
