A former deputy constable is expected to plead guilty to federal charges of conspiracy as part of an investigation into bribery in the Perry Township constable’s office. As part of the plea, Michael Sherfick is expected to tell federal investigators about others involved. The investigation focuses on more than $30,000 worth of alleged bribes paid by local businessmen. In return, investigators say, the businessmen got deputy constable badges and police powers. He'll also have to say whether any money was funneled into the political campaigns of constable Roy Houchins and other Marion County Republicans.
