“I am a criminal defense attorney practicing in both the state and Federal courts in New York since l988 and was a prosecutor for 14 years before that. l have used Jim Dowd’s services as an investigator many times over the last ten years. I can say without reservation that he is an excellent investigator. His efforts and professionalism are second to none. He has an easy—going manner that encourages even potentially hostile witnesses to speak with him. I would certainly recommend him to any defense attorney that needs any investigation conducted.”
