Foul play is not suspected in the death of A 22-year-old Murphysboro woman whose body was found in the Crab Orchard Wildlife Refuge on Thanksgiving Day.

Williamson County officials said Thursday they made their determination in the Jeannie Schuur case after an extensive investigation.

Schuur’s older brother told the Southern Illinoisan that the facts don’t add up, and he is frustrated with the decision to close the case.

An autopsy determined that Schuur died of hypothermia, and was under the influence of alcohol and drugs at the time. She had been missing for several days before her body was found, after walking away from a party at a friend’s home.
