NORMAL – The McLean County coroner has released preliminary autopsy results indicating there was no criminality involved in the deaths of two Illinois State University students.

Sophomore Allison Zak of Schaumburg and freshman John Stephens of Wilmette were found dead late Thursday. The coroner said Zak was found unresponsive in Manchester hall and Stephens was found unresponsive in Hewett Hall.

Coroner Beth Kimmerling said the 19-year-old Zak's cause of death might be related to an undiagnosed seizure disorder or Crouzon Syndrome, which comes with several brain and skull abnormalities.
