Mercer County Corrections Officer Barry Fennig fingerprints Dan Uhlenhake, of Celina, who was booked into the new Mercer County Adult Detention Center Friday night as one of first 32 "practice" inmates. The exercise, which will be repeated one more time before "real" inmates show up Feb. 28, is designed to help corrections officers become accustomed to operation of the facility. Daily Standard reporter Margie Wuebker is among those spending 24 hours there. Her story and photos will appear Monday.
