Where are the accusers

IN THE Gospel of John 8:2-12 we have the account of a woman caught in the act of adultery. It is an account well worth the consideration necessary to draw out some of its amazing truths.
Jesus sat in the temple teaching an unnamed group of people who were obviously very keen to hear what He had to say. They were interrupted by a group of Scribes and Pharisees, those who in that time were entrusted with the teaching and application of the Law, who had a woman who had been caught in the act of adultery.

The first question that comes to mind is where was the man?
