Mary Farmer

Mary Farmer took an axe to her neighbor Sarah Brennan, stuffed her
corpse into a trunk, then assumed Sarah's identity and ordered the
deed to Sarah's house transferred into her own (Mary's) name.
She then evicted Sarah's husband (who had no idea where his wife
was) from the house and moved into it herself, bringing with her
the trunk containing Sarah's corpse.  When she was found out, 
Mary tried to pin the murder on her own husband James.
