I don't think LE has cleared any of the Anthony's. They've said they were cooperating with the investigation. That statement really doesn't mean anything. I've seen this in other cases. The next thing we know the people who are supposedly cooperating, are charged and arrested. IMO, LE will avoid announcing to a suspect whenever possible that they are under an investigation, and facing possible arrest. People can cooperate with LE all they want. It does not mean the person is telling the truth, are not involved and not facing an arrest.
I do remember several statements by LE that ZG associated with Sawgrass Apts. was cleared of involvement.
