Cole Werhan, 28, of Burlington, Connecticut, has been charged with murder in the death of 26-year-old Janina Brooke Murphy, who was found dead at the bottom of a staircase in March. The medical examiner ruled her death a homicide from blunt force head injury, confirming family suspicions that it was not an accident. Werhan was arrested Tuesday and is being held on a $5 million cash bond.
