I was charged with First Degree murder and Marc Caudel was appointed as my investigator.  Not only did he prove the State was hiding evidence that was favorable to my case, he recognized that my “confession” was false and found the right expert to prove my innocence.  If it were not for Marc and his investigation, I would most likely be spending the rest of my life in prison.  Thanks to him, I was found not guilty and was able to go home to my family.
