(KSL News) -- A Bountiful Junior High School says she's innocent of threatening violence at her school.
Sandra Wariner entered the plea yesterday.
Wariner was arrested in May, after she allegedly told the school principal she'd bring her gun and shoot him and others, if she didn't get the class assignments she wanted.
At the time of Wariner's arrest, police confiscated two guns from her home.
Bountiful police say she may suffer from mental difficulties.
Another hearing is scheduled for August 26.
If convicted, Wariner could be sentenced to up to 15-years in prison.
