EDWARDSVILLE, Ill. -- The Madison County coroner says an autopsy on a Southern Illinois University student from Quincy whose body was found in her housing unit on the Edwardsville campus failed to show why she died.
Steve Nonn says the body of Tifani Wilder was found Thursday after officers responded to a call from the mother of the 24-year-old woman's boyfriend to check on Wilder's well-being. Nonn says Wilder's 5-year-old son was found in the apartment unharmed.
Wilder is a 2006 graduate of Quincy High School. She graduated from John Wood Community College in the spring of 2010. Wilder was a junior at SIU-Edwardsville, majoring in psychology.
Campus police say Wilder's death doesn't appear suspicious and nothing indicated anyone forced their way into the apartment.
According to the Edwardsville Intelligencer, Wilder's son told officers that his "mommy would not wake up." Police found Wilder lying on her bed.
Wilder did not have a roommate.
The university's housing staff was caring for the boy on Friday until state child-welfare workers or a relative could take custody.
Lab tests on samples of Wilder's blood are pending.
