from The Republican (Danville, Indiana) - issue of Thursday, April 25, 1901 - page 1, column 5:
William Lewis, former commissioner, was adjudged insane Monday and has been taken to the asylum. He had been in a sanitarium at Indianapolis last week and came home Saturday in bad condition. Saturday night and Sunday he was violent, exhibiting homicidal tendencies. This is a most sad ending of Mr. Lewis's condition which has been a serious matter for some months. A few weeks ago he was in this office and seemed in fair health and expressed his confidence that he would soon be himself.
