A Wood County judge has sentenced a 43-year-old Nekoosa man to a life prison term.  Paul Carter was found guilty of first-degree intentional homicide last February.  He had been accused of killing his girlfriend’s disabled 20-year-old daughter, Samantha Roberts. She was found unresponsive in January of last year and she died before she could be taken to a hospital.  An autopsy pointed investigators at Carter’s involvement in the daughter’s death.  She wasn’t able to walk or talk.
