It has only taken what...9 months for him to do it, but Robert Adams has finally entered a plea of 'not guilty' to the charges he is facing. I was not there so I am unsure of the exact details, but according to news sites, he has pleaded not guilty to all seven charges (6 felonies and 1 misdemeanor.)
From here the process should go to a preliminary hearing and then, if the judge finds the prosecution has enough evidence, a full trial. Of course a plea deal could be reached at any time.
The court appearances haven't ended yet this month for Mr. Adams. He is also due back in court on May 31st for a case management conference regarding the civil case with Stonington Insurance who has asked for a dismissal without prejudice of their case. Presumably this is because the other civil case against Mr. Adams was dropped until after the criminal hearing was completed.
EDITED TO ADD
The Preliminary Hearing in the case is set for August 17th, 2012, more than a year after the school was initially closed. Eleven months after he was arrested on seven separate counts of child molestation.
