The stepsister, two men and three juveniles were quickly arrested.
But prosecutors are not trying the kids as adults, as they initially planned. Also, police say they don't have enough evidence to make more arrests.
The little girl's stepfather spoke out in defense of three of those charged and DNA tests showed no semen on the child.
Prosecutors offered the juveniles plea deals to testify against the adults.
So far, no one has pleaded guilty.
Defense attorneys say the case is falling apart. Prosecutors say they plan to bring it to a grand jury soon.
