One of the most important elements of a successful criminal defense is having an experienced Criminal Defense Investigator on your defense team. An experienced Criminal Defense Investigator will develop information, secure potential witnesses and/or evidence as soon as possible to ensure the integrity.

An experienced Defense Investigator is needed to investigate the facts to support the client as well as investigate the evidence of law enforcement to possibly uncover any deviations and/or any oversights of new or missed evidence. Attention to the smallest detail is critical.

Far too often the investigating officer will draw a conclusion and form their opinion before the case is investigated. Criminal defense investigation is about finding mistakes and holes in the prosecution’s case and uncovering evidence and witnesses which will refute their claims—perhaps even an alibi. It also can involve finding what is called “exculpatory evidence”—evidence which might have helped the defendant, had the prosecution revealed its existence to the defense. If law enforcement interviewed any witnesses who are not on the State’s witness list, a defense investigator should speak to them, for sure. Defense attorneys like to know ahead of time what a witness is going to say, if possible.

It also helps to visit the scene of the crime, even though it may be weeks later. It helps form a picture and may point to areas which were neglected or not followed up on by the investigating party for the prosecution.

One question which should be asked of law enforcement personnel who were on the scene of an incident is, “At what point did you determine a crime had been committed?” If an officer is headed to a call with a predetermination that a crime is taking place, an arrest is imminent. If not, what fact at the scene changed his mind?


A criminal defense investigator will review the police investigation and re-interview witnesses to find changes in their stories and to develop new and independent leads. A criminal defense investigator’s role is to find witnesses and evidence that will establish reasonable doubt that will show the jury that there is reason to believe that the defendant is not responsible for committing the crime.

The professional criminal defense investigator must talk to all witnesses; analyze all the evidence (including physical, video, audio, photographic, etc.) in discovery that is compiled by the prosecution. It is the defense investigators responsibility to locate these witnesses, retrieve accurate statements and identify information to contradict the case that law enforcement is building as well as changes in witness’ stories from their original statement. This means that the investigator must be knowledgeable about the case and skilled in interviewing techniques and interviewing methodologies.

A professional defense investigator will have the knowledge to review evidence and reports and determine whether or not what the prosecution claims are consistent, accurate and truthful. It is not uncommon for a skilled investigator to uncover inconsistencies or unusual information in reports that will give rise to avenues of investigation favorable to the defense. The main objective of criminal defense investigation is to break down prosecution witnesses by utilizing vigorous cross-examination techniques. This can help reduce and eliminate their credibility and the weight given to their testimony.

While a professional investigator is not expected to be an all knowing, omnipotent person, his experience should have provided him with a broad knowledge base. For example, he must have some knowledge of serums and blood stains, human anatomy, ballistics, firearms and forensics. He must also understand crime scene reconstruction, photography and evidence collection procedures. In addition, a good professional criminal defense investigator will also know how to conduct research, locate governmental records, utilize computers and will have a working knowledge of criminal law and procedures.

Effective defense investigators also have developed a networking system with other investigators in order to be able to utilize the services of other investigators in other jurisdictions should it become necessary to locate a witness or conduct other investigative activities when required. This networking ability also aids the investigator when he is called upon to locate expert witnesses necessary to assist in the case.

A professional Investigator must have a total understanding and working knowledge of the Rules of Evidence so that he will be able to obtain and preserve evidence that will be admissible at trial. This includes understanding the rules concerning privileges, hearsay, admissions, confessions and co-conspirator statements, declarations against interest as well as those made as part of the res geste of the crime or incident being investigated.

Professional investigators also know and follow high ethical standards in all of their activities. This knowledge must also include an understanding of the Legal Canons of Ethics and how the investigator’s actions may impact upon the attorney for whom he is working. For example an investigator working for one of several defendants, must understand that he cannot interview the co-defendants without first obtaining their attorney’s approval.
