Improvements are needed, Champlin said.The jail was built more than 50 years ago, and the cells no longer lock because they were permanently opened in the 1980s or 1990s to make more space to house inmates, according to the sheriff.The jail has 22 beds and employs nine full-time corrections officers, four females and five males, Champlin said. No male corrections officers were working Saturday night.
