KETTNER HAD A MOTIVE.

Dr. Kettner had a motive, which made this clew seem the right one for such a deed as committed at Fort Thomas. Being a bigamist and fearing that his first wife, who followed him so many miles, would prosecute him, his only hope was to secure the marriage certificate and other evidence against him. The Engelhardt girl always carried the marriage certificate in her bosom, beneath the corset, and more than once said she would never part with it.
