murdrum

MURDRUM, old Eng. law. During the times of the Danes, and afterwards till 
the reign of Edward III, murdrum was the killing of a man in a secret 
manner, and in that it differed from simple homicide. 
     2. When a man was thus killed, and he was unknown, by the laws of 
Canute he was presumed to be a Dane, and the vill was compelled to pay forty 
marks for his death. After the conquest, a similar law was made in favor of 
Frenchmen, which was abolished by 3 Edw. III. 
     3. By murdrum was also understood the fine formerly imposed in England 
upon a person who had committed homicide perinfortunium or se defendendo.
