There is one topic in which investigators, journalists, ministers and therapists all agree that a follow up interview is necessary:
It is called "trickle truth" and under all circumstances in which information is needed regarding sex, whatever information was first received in the interview is not the full story.
The guilt associated with human sexual inappropriate behavior meets a resistance in the brain that even during a confession or admission, the odds are very much that you have not gotten the whole story.
Even in romantic scenarios where the injured party heard, "we are just friends!" the word "just", without training, tells them that something 'doesn't feel right.'
It is because the word "just" is used when the subject is comparing what he is saying to something else.
That something "else" is on his mind need to be disclosed.
In even rape confessions, the first 'round' of information is going to have details omitted deliberately via resistance.
Even in rape victims, we find a hesitation to be open about what was done: in detail. The shame and humiliation will often only allow some things to come out, and if the sexual assault was within an already "domestically violent" home (where little if any actual violence takes place: most victims are controlled by the threat of violence making physical violence of little necessity) the disclosure must have a follow up interview.
For the criminal investigator:
the greater the gap in the original lie, the greater the necessity becomes for, perhaps, a third interview.
The third interview by the criminal investigator often means the difference in punishment.
Busy investigators, once enough information is obtained for an arrest, later learn of a plea struck that deeply frustrates them. They investigated, interviewed, interviewed again, got the confession or admission, and felt it was enough.
The third interview, after the confession, is often short in duration, but rich in information.
I urge investigators who feel they know the info and have "enough" for an arrest, to consider this:
1. Most admissions and confessions are in the subsequent interview. Psychologically matching statistics, but for another article. This is a broad statement.
2. The confession came in the follow up interview: consider the following...
what you received even in the admission, has been minimized by the subject, even if it acknowledges criminal activity. What is going to be pled to will be minimized further. You have the success of gaining the arrest: The third interview is specifically designed to 'flesh out' all the skeletal details you received. It is close to a guarantee: if you got enough to arrest in the 2nd, a short, 3rd interview, will so unnerve the guilty party who has 'already' unburdened himself, yet not fully, will be surprisingly cooperative as he sees you as his 'confessor.'
All that is needed is this:
The guilty should be complimented on their admission and then be told:
"the facts of the case show that you have told the truth, but there are some things you still need to tell me, to tell the full story..."
The one who has admitted the sexual contact will now, when shown the specific admission, not want to "lie" about it and will fill in the missing details.
Take what he gave you in the admission, and know that logic says what human nature says:
it went further.
It is closely related to what an addict owns in how many drinks or pills he had when he confessed. It is very likely to be...
a few more.
With human nature's powerful defense mechanism internally running at full power to blunt the guilt, the truth in sex 'trickles out' even when you think it was flowing.
There is more.
Going the extra mile might make the difference between jail time and community service as 'the devil is in the details' and the truth will bother, and sometimes even sicken not only judges, juries prosecutors and investigators,
but defense attorneys, too.
Even in the confession, when you hear, "we just..." or "I just..." take it as a linguistic signal to dig deeper, or deliberately intend the third short interview.
It will be short.
