William Smith, 27, was arrested Friday for the murders of Alma Jean Owens and Macarthur Jackson.
Smith's arrest is of little comfort to Jackson's family, who now have more questions than answers.
"I would just like to ask Will Smith, 'How could you?' My father has raised you, clothed you, fed you and housed you," said Jackson's daughter Natalie Chapman.
Chapman and other family members gathered Saturday night outside the apartment where the two victims were found.
They say the fact that they know Smith makes dealing with the murders that much harder.
Chapman cried, "I want [Smith] to have a painful death. [He] took my father away so easily, so quick."
Jackson's older brother Joseph Jackson said Macarthur had a big hear and would help anyone, especially Smith.
"Took him in when his mom, dad didn't take him and he quickly became like a son," said Joseph. "He told me how much he loved him and what all he had done and then he would do this to him? That's what hurts. That's the hurting part."
Community Activist and Reverend Pete Mingo says these two murders shouldn't discourage anyone from fighting against violence.
"We need to pray for both families for healing and healing for our community and just let the process take place and let God basically be the judge," said Mingo.
