Six Step Formula for Investigative Interviews

Six Step Formula for Investigative Interviews

Investigative interviews need to uncover the full facts of an event that has occurred. Therefore, investigative interviews need to be professionally undertaken to ensure that all relevant information is gleaned and accurately recorded from all victims, witnesses and suspects, using the following formula:

1. Listen with 100% attention.

Investigators must give one hundred per cent full mental focus to the interview process. Interviews are mentally taxing and require full concentration. Investigators need to ensure environments in which interviews are conducted, allows for full concentration and good listening without distraction.

2. To ensure complete understanding, we take accurate written notes.

Ultimately, the investigators' purpose is to gather and record evidence sufficient to write a report, that will allow decision makers to make wise decisions. The process of writing takes place during the interviews.

3. Ask questions to gain more specific details.

Most people use vague terms and ambiguous language, which is the OPPOSITE of the language style that investigators use. So we ask questions to translate vague, opinionated and subjective language to make it more specific, factual and objective.

4. Identify, highlight and question any contradictions.

Investigators seek out and (if possible) resolve contradictions. If we cannot resolve them by careful questioning and examination, then we HIGHLIGHT unresolved contradictions in our final report to the decision makers.

5. Confirm that the chronological order of the narrative is correct.

Investigators not only need to discover what was said and done; they must also know the exact sequence of events. The right events recorded in the wrong order, is wrong.

One of the most common ways that guilty people lie, is to change the order of events. Investigators should think of events as being caught on old fashioned cine film, with each frame "representing a certain period of time, in which things are said and done". Investigators need to conserve and record into each "time frame" the correct words, behaviour and events.

6. Construct a complete written narrative.

Investigators write their notes in full view of the person being interviewed. Ideally, notes should be endorsed by the interviewee as being a correct record of the interview.

This makes the investigative process more open and honest, and it stops interviewees later claiming that reports written by investigators contain errors, or omissions.

The narrative recorded in the notes should be as complete as possible as they form the basis of the final report that is given to decision makers.

investigative interview

An investigative interview is a work process where a trained interviewer listens and asks set questions to learn the real facts of an event. It must gain a full, clear and true record. The interviewer writes notes during the talk and puts each piece in the right time order. The meeting follows fair and legal rules so managers can later use the notes as strong evidence for wise action.

Frequently Asked Questions

Common questions about this topic

Give full attention. It is step one of six key interview steps that underpin every strong investigative interview.
Real-time note taking fixes facts while they are fresh, aids evidence gathering, and shows the interviewee you record honestly.
Pick the unclear word, then ask who, what, where, when and how until the reply changes to concrete, measurable detail.
Put each clashing point to the speaker, seek extra facts, and record any conflict you cannot clear for managers to judge.
A wrong sequence hides truth; liars often swap events. A clear timeline lets decision makers see cause and effect.
Use your notes to join each event in order, include quotes and actions, then read it back to confirm none are missing.
Yes. Let them read and sign each page. This openness builds trust and stops later claims of error or bias.
