PONTIAC, Mich. —  A medical examiner's office in Michigan has canceled public school tours after a high school group watched the autopsy of a 14-year-old girl from their district.

The Detroit News reports Monday that Oakland County officials decided to stop the tours in Pontiac after they were contacted by the girl's parents, who were very upset about the March tour.

Mike Zehnder, the county's director of public services, says it was "a poor decision" to let the tour go on.

The newspaper reports the teacher who brought in the Waterford Kettering High School group was told the autopsy would be of a Waterford middle school student and discussed that with students.
