A Mountain Home woman arrested last week has been ordered to undergo a mental evaluation. 55 year old Ellen Marie Griest was sent to the Northwest Arkansas Hospital after her court hearing Tuesday. Griest allegedly believed that a group of 17 students at ASU-Mountain Home Technical Center were members of a drug cartel and it was her duty to take them out. During her hearing she allegedly told the court that paying for her mental evaluation was a total waste of taxpayers money.
