Daisja Weaver has been missing since early June 2009 after her 19-year-old mother, Tamaira Creagh, said a man broke into her apartment and kidnapped the baby.
Police eventually arrested Creagh on an evidence tampering charge, and she told police that she and Weaver dumped the child's body into Lake Lewisville with a sandbag tied to it after she died while in her father's care.
However, Weaver testified that Creagh was the one who killed the child.
The girl's body was never found.
