Officers tell us they responded to the home about 3:15 Saturday afternoon. They were called by a friend of the victim who was scheduled to come over for a visit, opened the door and found a woman dead inside.
Later officers also discovered the woman's husband dead in the home. All we know of the couple is that they are black and in their 60's.
