(CNN) -- The body found in a creek near Indianapolis is not missing Indiana University student Lauren Spierer, a medical official said Tuesday. Forensic tests found no link to Spierer and have determined the body belongs to an African-American female, said Alfarena Ballew, chief deputy coroner for Marion County. Officials believe the decomposed body had been in the creek for about two and a half weeks before it was discovered on Sunday. Bloomington police have been searching for Spierer, a 20-year-old sophomore, since June 2, when she was last seen leaving a sports bar after a night out with friends.Forensic tests confirm body found in creek is not Lauren SpiererThe 20-year-old Indiana University sophomore disappeared June 2Investigators have not been able to make any progressThe coroner's office will use DNA and dental records to identify the body
