My question involves criminal law for the state of: Florida

On Jan 23, 2011 my wife was arrested on 3 counts of "obtaining or attempting to obtain a controlled substance by fraud" with bail set at $4000.00 costing me $400.00 to a bail bondsman to get her out. On May 12, 2011 she was notified by mail that all charges were dropped. My Wife was extremely happy that the charges were dropped but was embarrassed by the whole ordeal and adamant to get to the bottom of why this all came to happen. Now here come the hard part on May 17, 2011 my wife passed away but I feel compelled to continue and get to the bottom of the wrong done to her.

I have contacted the public defenders and they told me that I needed to talk with the state attn to find out why they dropped the case. I talked with the state attn. and they said I needed to talk with the detective that investigate the case. So I talked with the detective and he told me that she was arrested because she was in pain management and also received narcotics from another doctor. I told him that both her pain management and the other doctors were all aware of the situation and he said yes but when he did the investigation one of the doctors said they had no knowledge that she was in pain management which lead to the arrest but it was his understanding that during a deposition the doctor said I miss read my note and admitted to knowledge about her being in pain management. So this is why the case got dropped and he went on to say that my wife had done nothing wrong.

My question is who is at fault here... The doctor for making a mistake and saying she didn't inform them she was in pain management, The detective for poor investigation work or the State Attn for authorizing an arrest on such flimsy grounds. And what avenue should I take from here?

Thank You in advance
