Executed:  19 April 1907
NOTES:     Executed "for the murder of his father, mother, and 
           brother, in Dayton, on the night of November 4, 1905, 
           while under the influence of drugs.  It is said that 
           he administered a powerful drug to the members of his
           family and while they were under its influence he
           murdered them with a knife, after which he set fire 
           to the building.  While fleeing from the building he
           was captured and his crime discovered.  He was a
           highly educated man, but the use of a powerful drug
           transformed him from a Dr. Jekyl to a Mr. Hyde.
