Mary Ruby Martin Baker, an 85-year-old widow from Ahoskie, North Carolina, was shot to death in her home shortly after midnight on March 2, 2014, when an intruder broke in and shot her in the heart. The killing shocked a small, close-knit community where she was known for walking the neighborhood, chatting with neighbors and encouraging others to exercise.

Family members have held remembrance ceremonies and urged continued efforts to find the killer; police say tips have been followed up on but the case remains unsolved.

Anyone who knew Ruby or who has information about that night is asked to come forward with even the smallest detail that might help solve her murder?
