“It’s sad to cut down two young ladies in the prime of their lives over what? We still don’t have the answers over why? We need closure. We need to know,” said Brown.

The two young women leave behind three small children, who now have nothing around the holidays because everything was burned in the apartment.

“We have to figure out how to explain this to them that their moms are gone,” said Turner.

Police said Tuesday night they don’t have any new information but over the weekend said they’re looking for security video.
