NORMAL, ILL. ? The search for a missing college student may have reached a critical point, as officials in Mississippi waited Tuesday for medical and dental records to determine whether a body found in a burnt-out chicken house could be that of 21-year-old Olamide Adeyooye.

Elsewhere, investigators continued to interview several “persons of interest” in a case that gained attention through an Internet campaign launched by Adeyooye’s friends.

The popular senior at Illinois State University had been studying laboratory sciences and biology, and was due to graduate in December. She was last seen nearly two weeks ago at a video store near her apartment in Normal, a college town in central Illinois.

Mississippi authorities notified Normal investigators about an unidentified woman’s body Monday in response to a nationwide alert seeking Adeyooye and her car, Kotte said. The car, a green 1996 Toyota Corolla with Illinois license LBG927, remains missing.

The body was found Friday morning near Interstate 20 in the central part of the state, Delores Lewis, a Mississippi Department of Public Safety spokeswoman said in a statement. Firefighters put out a blaze in the chicken house four days earlier, and workers found the body as they were cleaning up the site, the statement said.
