Since you say you know everyone involved, that causes me to think you should be questioned by law enforcement authorities that have nothing to do with Key West or the Florida Keys. Say, the FBI and the US Department of Justice.
If I were Dennis Ward, I already would have asked the Feds to take over the investigation, including investigating the Monroe County Sheriff Department and my prosecutor, Coleen Dunn. I also already would have asked the Florida Governor to appoint a special prosecutor from the mainland to replace my office as the prosecutor. I also already would have asked the Advisory Committee to the Florida Supreme Court to investigate and recommend a circuit judge from outside the Florida Keys be assigned to preside over the prosecution henceforth.
