Interview witnesses

  • Develop rapport

  • Prepare interview reports suitable for use in all types of cases including civil or criminal investigations

The Mason PI team developed an expertise in interviewing witnesses during their decades conducting successful investigations. Success cannot happen unless the investigator has the ability to talk to people. A case cannot be successfully concluded unless you have a witness to tell you what happened. Sometimes we find a smoking gun and think the case is solved and the bad guy is going to jail – hook, line, and sinker.

In a very simple example, say you have discovered the ransom note at the scene of a bank robbery. If you have to go to court, you will need the bank teller, the other bank employees, customers, security guards, or other people who can testify and tell the jury what they heard or saw related to the ransom note. Without a witness, your evidence can’t complete the case.

A comprehensive interview report is prepared after the interview of each witness for case use or submission to court in civil or criminal investigations.

If you tell the truth you don’t have to remember anything.  
— Mark Twain


  • After Jane retired from the FBI, she was asked to provide interview training to a multi-national law firm.  Law school does not help future lawyers become experts in witness interviews.  A majority of lawyers must talk with clients, witnesses, jurors, judges, law enforcement officials, and colleagues each and every day of their careers. The ability to successfully talk with people is crucial.
  • We developed a four-hour block of training for an audience of fifty attorneys and executive management of the firm. The training included a Powerpoint presentation, extensive role-playing, and hand-outs with interview tips and techniques.
  • One of the tips Jane shared at the training was her practice to ask each witness at the end of every interview if there was anything else he or she wanted to say that hadn’t already been discussed.  Sometimes there are events critical to your case that you have not yet discovered.
  • A majority of the time, the witness said there was nothing else. The handful of times that the witness had more to say paid off immeasurably. In one instance, the information provided after the substantive interview was a matter of national security importance.
