A Naperville North freshman died suddenly Tuesday morning, school officials said. This is the fifth sudden student death at NNHS since December of 2015.

Teachers and staff were notified about the death through an email sent by NNHS Principal Stephanie Posey. Teachers read an announcement aloud to their second period classes to inform students. No cause of death was listed in the announcement.

In many cases teachers and students learned of the death at the same time.

In an email sent to parents, Posey said there are additional counselors, social workers and psychologists at NNHS Tuesday, and they will remain there as long as necessary.

If you or someone you know is in need of help, call the DuPage County Health Department Crisis Intervention Unit 24-hour hotline at 630-627-1700.
