In the fall of 2010, Roberta “Bobbie” Miller was starting over. She had a new home in Gilford, New Hampshire, she was back in school, and she was making plans for the life ahead of her. Then, on Halloween weekend, Bobbie and her dog, Sport, were shot and killed inside that home.

There were circumstances that seemed to point suspicion in one direction. But as the years passed, some members of Bobbie’s own family began looking somewhere else entirely.
