ROCHESTER HILLS, Mich. (AP) -- A Rochester Hills teacher was fired after an investigation into inappropriate relationships with students.
The Oakland County Sheriff's Department has also launched a criminal investigation.
The school district sent a letter home to parents, but it didn't have a lot of details.
It reportedly happened with two different students after hours at two off-campus locations. Authorities say the incidents took place at a home and in a vehicle in November and December.
Kathryn Houghtaling, 26, from Sterling Heights, was a Special Ed teacher at Rochester High School, and was arraigned on Friday.
She has been charged with six counts of criminal sexual conduct in the second-degree. She is accused of having sexual relations with two boys, 16 and 17. Prosecutors say that one of the students was in her class. Defense attorney Zachary Glaza said in court Friday that the student was assigned to Houghtaling's classroom due to a reading deficiency.
She pleaded not guilty and received a $200,000 bond, cash or surety.
If she does post bond she will have to wear a tether and undergo drug and alcohol testing, as well as staying away from all public schools.
She is being held at the Oakland County Jail.
She returns to court Jan. 24 for a probable cause conference and Jan. 30 for a preliminary examination.
