Jack and Jill murdered the White man to fetch the pale if money. In the process, they murdered Jill's White husband to run and live happily ever after on his insurance money. 

Here's the description from Fox Carolina:

"Crystal Gail Williams, 34, and Marcus Channing Johnson, 35, were both charged with murder in the death of Shane Williams, Crystal Williams' husband, Clark said during a press conference Thursday.

He said the motive for the killing was to collect a $250,000 life insurance policy on the victim.

According to warrants, Crystal Williams unlocked the kitchen door of the family's Devon Court home for Johnson, who then entered the home early on Jan. 26. Warrants stated Crystal Williams awoke her husband and told him the fire needed wood.

That's when deputies said Shane Williams, 38, walked into the living room where Johnson was waiting. Johnson then shot him three times,  killing him, according to warrants. "
