Kiaya Campbell's father was living with a woman who has identical twin sons, fifteen years old.  One of the boys allegedly walked with Kiaya to the store.  From the article - "The boy who was with Campbell Wednesday night told police investigators that the two had been walking together, back to a home where Campbell’s father lived, when they became separated in a rain storm. Some neighbors have disputed that there was a rainstorm in the area that night."  Bottom line - Kiaya was not related to the young man who is accused of killing her.
