It might help to read the OG Remit and part of The Portuguese Archiving process in conjunction then explain convincingly how one reconciles "whole of the investigations" with only abduction when the PJ investigated more than abduction. Don't work any too well do it?
Op Grange Remit
The support and expertise proffered by the Commissioner will be provided by the Homicide & Serious Crime Command - SCD1.
The activity, in the first instance, will be that of an ‘investigative review’. This will entail a review of the whole of the investigation(s) which have been conducted in to the circumstances of Madeleine McCann’s disappearance.
The focus of the review will be of the material held by three main stakeholders (and in the following order of primacy);
• The Portuguese Law Enforcement agencies.
• UK Law Enforcement agencies,
• Other private investigative agencies/staff and organisations.
The investigative review is intended to collate, record and analyse what has gone before.
It is to examine the case and seek to determine, (as if the abduction occurred in the UK) what additional, new investigative approaches we would take and which can assist the Portuguese authorities in progressing the matter. Whilst ordinarily a review has no investigative remit whatsoever- the scale and extent of this enquiry cannot permit for such an approach. It will take too long to progress to any “action stage” if activity is given wholly and solely to a review process.
The ‘investigative review’ will be conducted with transparency, openness and thoroughness.
The work will be overseen through the Gold Group management structure, which will also manage the central relationships with other key stakeholders and provide continuing oversight and direction to the investigative remit.

From PJ Archiving Document
The investigation, during more than 13 months, followed all the credible indices related to different hypotheses and, in an impartial manner, continued to analyse, correlate and synthesize them, looking for an explanation for the happenings of the night of 3 May 2007.
Assuming that the minor's disappearance was due to the acts of third parties, the PJ explored various lines of investigation, not excluding any hypothesis considered plausible or hypothetically acceptable.
From the documentation, you will observe that during the investigation various possibilities were contemplated.
As such, consider:
1. abduction, for sexual exploration or other (e.g, later adoption, child trafficking, organ trafficking), without homicide;
2. abduction, followed by homicide with (or without) hiding of the corpse;
3. accidental death, with later hiding of the corpse;
