A prosecutor said Cole Werhan, the man charged with murdering a Duxbury, Massachusetts woman inside a Connecticut home, has several open domestic violence cases. Police say Werhan killed 26-year-old Janina Brooke Murphy inside the Burlington, Connecticut home where she was living. Murphy was found at the bottom of a staircase on March 29, but no charges were filed until Tuesday. Werhan was arraigned Wednesday in Torrington Superior Court in Connecticut.
