Eddie indicated a corpse was inside the apartment. If death happened it leads to the night of 3 May and yes the many inconsistencies of that visit only hours before she disappeared could suggest a cover-up. If there was a corpse then it was removed that night and the unidentified man who the eye-witnesses think was with Madeleine is the prime and only credible suspect in this case.
p.s. I know what normally happened at 6:30. It's in their statements.
Eddie 'indicated' in the garage ... there was no corpse there.
Eddie 'indicated' in the villa ... there was no corpse there.
Eddie 'indicated' all over the place in the apartment ... there was no corpse there.
Eddie 'indicated' all over the place in Haute de la Garenne ... there was no corpse there.
Eddie's indications were no doubt of interest to investigators, until they were checked out ... Eddie's documented proven alerts when a body was present did just that ... his unproven alerts could have been to anything and nothing.
As far as being evidential goes that is exactly what they are ... nothing. Unfortunately the PJ of the time were a bit disoriented by the PR and didn't bother with the warning in the small print.
