The day started off with a parade of former co-workers who testified about the layout of Nathan Hale and how they would routinely go into Shad Knutson's room or walk by and look in.
On several occasions Knutson was there with one of his alleged victims but none of the teachers witnessed any suspicious activity.
This afternoon Knutson took the stand in his own defense.
The prosecution laid out the case against him with the help of some of his alleged victims - today Shad Knutson denied the accusations.
Defense Attorney Tom Riley asked about the first accuser, "Did you touch her?" Knutson replied, "No sir." Riley followed, "Any of this exposing yourself to her in the hallway or she exposing herself to you true?" Knutson, "No sir."
Knutson explained for the jurors that he and the second alleged victim were often at odds over her in class cell phone use.
Knutson also explained away notes that read, Tell me then you can have it. Are you mad? and Are you going to let me feel it? As innocent interactions with students about who one student was texting, why another appeared down and a bet to touch a student's precious fur coat. All of those were male students.
Prosecutors will finish cross examining Knutson on Thursday before the jury begins its deliberations.
