OTTAWA - Authorities in eastern Kansas have evacuated a university residence hall and closed the campus after suspicious packages were found. The Franklin County sheriff's department says a package was reported about 5:45 a.m. Thursday outside Tau Jones Hall at Ottawa University. University spokeswoman Paula Paine told The Kansas City Star (http://bit.ly/12ln0cG ) that campus security found other packages at other buildings, and the campus was closed about 7 a.m. The buildings were evacuated and people have been warned to stay off campus. Paine says authorities are investigating the possibility that the packages could be related to a scavenger hunt that students held Wednesday. The university has about 550 students at the Ottawa campus, which is about 50 miles southwest of Kansas City.
