A judge has dismissed a criminal case against a woman authorities say had sexual relationships with three students she taught while serving as a substitute teacher in Bay City.
MLive.com reports (http://bit.ly/MdLm1V) Bay County Circuit Court Judge Kenneth W. Schmidt on Tuesday dismissed all six counts of third-degree criminal sexual conduct with a student faced by 43-year-old Heidi Lewis.
Prosecutors are considering whether to appeal.
The Midland woman was a substitute at Bay City Central High School, teaching a special education course from January 2010 for several months.
Authorities were alerted about the alleged incidents after a girlfriend of one of the teens told a school official after her boyfriend spoke about having sex with Lewis. They began their investigation in January 2011.
The judge says Lewis wasn't under contract as a teacher during the summer of 2010, the time when the students say they had sex with her.
Three of Lewis' students testified that they had sex with her multiple times after school ended for the summer. They were 17 at the time.
While Michigan's age of consent is 16, the law doesn't apply when the sexual contact is between a teacher and a student. Then the student must be 18 or older.
A mistrial had been declared in the case in March.
