Criminal Defense Investigations

At Diamond and Mann, we specialize in conducting full service criminal defense and mitigation investigations. We are Justice Administrative Commission (JAC) approved 6th Amendment vendors.  We have extensive experience in reviewing criminal cases for legal accuracy, completeness and procedural appropriateness.

As former law enforcement officers, we are intimately familiar with the concepts of reasonable suspicion, probable cause and reasonable doubt. By applying our investigative methodology to your case, we can ensure that your defense team is well prepared and has the opportunity to present the defense’s case in a robust, complete and accurate manner.


By reverse-engineering probable cause in a given criminal case, we can determine if the arresting law enforcement officer acted appropriately and within the guidelines of both the law and departmental procedure. If you client is indigent for cost (IFC) for private investigative services, we may be able to provide excellent criminal defense investigative work to you and your client at no cost.

Our investigators are well respected within the criminal defense community and have successfully investigated high level felony cases such as first degree murder, sexual battery, armed robbery and many, many more. We guarantee that our investigative efforts will prove invaluable to your defense team.
