Walter Benjamin Robertson asked his longtime girlfriend Della Crottinger to marry him. Crottinger must have been quite besotted with Robertson because did not delay in answering, "yes." A decision she would soon regret.
How soon? How about later that same day. Robertson brutally murdered his fiancé. He confessed to the murder on the grounds of insanity. He was extensively interviewed by the County's physicians and found to be quite sane and more than able to stand trial for the vicious murder of Della Crottinger.
Rather than revealing his motive, he took his secret to the grave when he hanged himself in his cell at the Old Jail. If this shady character is still lurking around the cell block, perhaps you'll be the one to unveil his hidden secrets!
