What did he write in the sand

Sometimes I wonder what Yeshua had wrote in the sand when they brought him a woman caught in adultery. There was one thing I have missed out of all my reading of this story. She was caught in Adultery where was the man who would have committed adultery with her. Why was he not brought in this was one thing that was recently brought to my attention.
In John 8:4-5 Then they said to him “Rabbi, this woman was caught in the very act of committing adultery, Now in our Torah, Moshe Commanded that such a woman be stone to death. What do you say about it?”
In Exodus we are given the laws of G-d the 10 commandments and one of the commands is not to commit adultery. Leviticus 20:10 If a man commits adultery with another man’s wife—with the wife of his neighbor—both the adulterer and the adulteress must be put to death.
It seems me to me, if she was caught in the act the man should be there because wouldn’t he have been caught also in the act. It not just the woman who sinned.
Yeshua news this was a trap, he said nothing but bent down and started writing. Could he have been writing the names of the men who committed adultery with him, could it have been everyone sins. In the bible we are not told what has been wrote in the sand just that Yeshua was writing in the sand. I think he was using his writing as a way to get the people attention, because first it was the old who lift then the young who lift. I am thinking that maybe the older people if the group lift first because he was listing their sins, or area of their life they struggle with, then the younger ones lift because they started realizing they to were with out sin.
The only one in that group who could have thrown a stone at the woman was Yeshua, because he was the one of them with out any sin. After all her accuser lift Yeshua looked up to that woman and asked her where are your accuser, and then he told her to go and sin no more.
Yeshua had basically did to her sin what a acne treatment does to zits he removed the problem that was resting on the woman head. I wonder if the man would have been with her for charges if maybe things would have been different.
