Careful review of the provided directions will facilitate success. It is important to achieve the objectives defined by the lesson. The process is similar to an investigation - understand the questions presented, define the objectives, engage the process with a methodology, pursue the answers and report the findings with confidence.
Test questions have been drafted in a manner that demands the participants study the question carefully in order to fully understand the question.  The concept is that the investigator is not an expert with all the answers.  The investigator is an expert in forming and understanding the questions necessary to uncover and secure an answer. Therefore, the testing process is designed to function as an investigation of sorts. The tests are open-book and the direct source is identified. Careful study is required to seek the correct answer. It may require more than the identification of one word or one line. Verification may require interpretation of an entire paragraph to gain a complete understanding of the idea being communicated.

Research and essay papers provide a measure of strengths and weaknesses relative to reporting, research, utilizing references, and communicating findings. In other words, the research essays and practical project is used to test research, investigation, report writing and review skills.  The importance of generating an accurate and professional report is paramount to a successful investigation as well as the reputation of the investigator.  The written report is often used as a subjective test to measure and rate the capabilities and expertise of an investigator. Therefore, this is the opportunity to recognize potential weaknesses and allow for improvement.

CDI-102-CEU-DL - $ 79.00 Includes Digital Training Materials, Forms, Link to Video, and Online Testing

The initial defendant interview is a key element in the criminal defense investigation process.  The interview of the defendant can make or break a case.  The defendant is often the best source of information leading to exculpatory evidence. In addition, it should be assumed that the defendant will be the most compelling witness, if not the only witness, for the defense. The defendant interview must be conducted in a professional manner utilizing proven methods.  


A 10 step plan of action is introduced that defines a professional approach to the defendant interview.  The process is designed to secure optimal results when combined with the individual investigator's experience and personal style.

1) Learn and become proficient in a proven methodology 
2) Secure a higher level of cooperation from defendants   
3) Enhance effectiveness during the interview process
4) Increase the recovery of information and facts

CDI-103-DL - REMOTE VIRTUAL CRIME/INCIDENT SCENE EXAMINATION - CDITC Continuing Education – 5 CEU units Awarded upon successful completion

CDI-103-CEU-DL - $ 79.00 Includes Digital Training Materials, Link to Instructional Video, online assignment, and evaluation. 

Why do we go to a crime scene days, weeks, or months following an incident? First, the reality is that law enforcement may have left or missed exculpatory evidence at the scene.  Second, the scene as reflected in the police reports may not be an accurate representation.  The inspection, photography, measurements, and diagrams recovered by a criminal defense investigator serve many purposes in respect to questioning evidence and the claims of witnesses. The criminal defense investigator must focus upon the field of vision and line of sight for those witnesses who were present at the scene.  At a minimum the visit should be done to facilitate what is often referred to as the “MY COUSIN VINNY” objective.  What do they claim they observed vs. what could they observe based upon the layout and critical features of the scene. 


The investigator is introduced to the preliminary virtual site inspection utilizing Google Earth/Maps. The virtual site inspection provides the investigator with the opportunity to examine the scene to engage in a comparative study of the facts and to identify additional leads in advance of the onsite inspection. Of course, due to distance and/or budget the virtual site examination serve as the only opportunity to examine the scene.   

1) Examine the scene using Google Earth & Maps

2) Utilize Google Measuring tools and mapping processes to question the claims of witnesses. 

3) Generate effective diagrams using satellite and mapping images reflecting location data and relative distances.

4) Generate demonstrative images reflecting the general line of sight and field of vision for  witnesses.

As a general rule, the communication between the defendant, defense counsel, and defense counsel agents retained to assist in the defense of a criminal case is protected under the attorney-client privilege and work product doctrine.  The extension of the attorney-client privilege to agents of defense counsel is commonly identified as the Kovel Privilege, deriving its name from the decision in the United States V. Kovel, 296 F.2d 918 (2d Cir. 1961).  The privilege is subject to all of the customary limitations of the attorney-client privilege.  Furthermore, the work-product doctrine must also be understood as it relates to all reports and documentation generated by the investigator operating as an agent of counsel. The work-product protection "shall protect against the disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation."  The rules must be understood by the investigator in order to effectively navigate the process.  The criminal defense investigator should always consult with the case attorney to discuss their interpretation of the rules as well as their policies.


The investigator is introduced to the protections of an agent of counsel as defined by the attorney-client privilege and work-product doctrines.  

1) Understand the confidential privileges provided to the criminal defense investigator as an agent of counsel.

2) Effectively apply the attorney-client privilege and work-product doctrine to all areas of investigation.

3) Document findings and generate reports consistent with the demands of the attorney-client privilege and work-product doctrine.

4) Enhance the investigator’s ability to effectively navigate the criminal defense arena.

CDI-105-CEU-DL - $ 59.00 Includes Digital Training Materials, Link to Instructional Video, and online test

COURSE DESCRIPTION:  The criminal defense investigator is presented with a steady flow of requests to interview witnesses as an agent of defense counsel.  The task is often followed by the comment, “I just need you to talk to the witness”.  Such commentary suggests that the task is simple and without complication. It is understandable that those lacking in field investigation experience would believe that it is as easy as showing up at the door of a witness or calling them on the phone. Of course, the reality is that the request is more than just one task and it is rarely if ever simple. Locating and establishing contact with a witness can be a problem that is impossible to overcome. Securing an interview is another issue. Difficult and uncooperative witnesses are routinely encountered during the investigative process. Each witness can present a unique problem that will require a unique solution. In addition, the obstacle and level of difficulty can be encountered on multiple levels.   


The investigator is introduced to strategies that can be employed to facilitate the process of managing difficult and uncooperative witnesses.

1) Understand the necessity of planning and preparation.

2) Effectively apply strategic and creative thinking.

3) Recognize the classification of a difficult witness and deploy and effective strategy to secure a successful interview.

4) Enhance the investigator’s ability to effectively navigate the criminal defense arena.
