The campus of Northern Illinois University has increased on-campus security after human remains were discovered in a nearby park.

There has been no word yet on whether the remains are those Northern Illinois student Antinette "Toni" Keller, who disappeared Oct. 14 after telling friends she was going for a walk near campus.

The Chicago Tribune has more on the finding:

Authorities on Saturday said they discovered human remains in Prairie Park nine days after Keller, 18, of southwest suburban Plainfield, reminded her friends to call her once they were out of class. The remains were found with various items consistent with some of Keller's belongings, DeKalb police Chief Bill Feithen said, declining to be specific. The remains appeared to be there for short time after Keller's disappearance, he said.

According to the Northern Illinois Star, the investigation into Keller's disappearance has been reclassified as a death investigation.

The search for Keller had involved 40 police officers and various student organizations. Keller loved to draw and was known to take long walks with her sketchbook.
