Park Tudor made the statement Monday evening in an email to parents.
The school also said there are no threats to the safety of the students.
The email reads, in part:
We have heard from some members of our community regarding speculation that Dr. Miller's death was linked to law enforcement's investigation of former basketball coach, Kyle Cox. We want you to know that throughout that investigation, we have been repeatedly assured by law enforcement that neither the School nor any of its employees (including Dr. Miller) were targets of their investigation. In addition, they have advised us that they are not aware of any threats to the safety of our students. We are continuing to work with law enforcement and Dr. Miller's interview was one of the standard witness interviews being conducted by the Cox investigators.
This is also the first time the school has acknowledged an investigation into Cox, who resigned in December 2015.
