Authorities on Wednesday positively identified the remains of Olamide Adeyooye, using dental records. No cause of death was released.
The Illinois State University senior's body was found Friday near Lake, Miss., in a burned chicken house that was being used to store hay.
Investigators here in Mississippi were able to match the missing woman's dental records with remains found at the scene of that fire, which occurred Oct. 17. The structure was located just off Interstate 20 in a small community on the Newton-Scott County line.
It wasn't until Oct. 21 that the body was discovered underneath the rubble, while the family who owned the land was cleaning up.
Meanwhile, Normal, Ill., police say they have several people to interview and re-interview in their investigation into the death of Adeyooye. Lt. Mark Kotte says authorities are still investigating how Adeyooye ended up in Mississippi.
A native of Nigeria who moved to suburban Chicago when she was eight, Adeyooye was last seen Oct. 13 at a video store near her off-campus apartment in Normal.
When Adeyooye went missing, it came as a shock and surprise to everyone who new her and she had many friends on the Illinois State University campus.
"She would brighten a room when she would come in. She'd make you smile and she'd make you laugh," said her friend, Colleen.
Those friends and fellow students had worked many hours over the last two weeks to try to help locate her. They put signs all over the campus and the city of Normal. They helped out police as they searched and they set up a phone bank, hoping for tips that would lead to her being found.
The disappearance has hit her long time boyfriend especially hard. Andy Wildreck and Olly, as they called her, had been together since high school.
"We used to write letters in high school to each other; we were attached at the hip," said Wildreck.
