Not only does a person get charged with criminal offenses and the potential of having their freedom taken away, it seems everyone wants that person destroyed. More often than not, the defendant is also sued in civil court, and in some cases also tried in federal court. Everyone deserves to be on even ground. The prosecutors have the police and DA investigators, the defense needs the same. Private Investigators are there to assist you and your attorney in your defense.
