The incident first came to the attention of police when the school’s principal, Michelle Young, contacted them. A friend of the student also told police she was aware of the relationship between the two. The friend showed police text messages between Koll and the student.

The student told police she deleted text messages on Koll’s instruction, “so no one would find out.”
