I think the PJ had already worked it all out with the software they allegedly didn't have but did have.
The old "we are but simple coppers from a third world country please come over to show us how this hangs together", ruse didn't work sadly, because by that time .......... make up your own ending. 
Pity it had to await the advent of the Rebelo investigation for information to be transferred to that state of the art software. Unless miscellaneous scraps of paper work just as well?

Expresso 20.10.07The new team that is led by Paulo Rebelo, the new coordinator of the Criminal Investigation Department of Policia Judiciaria (PJ) in Portimao, already has the Maddie case process digitalized into the personal computers. "It was a hideous amount of work", because the process' paperwork was "anarquically spread out", according to a source with PJ, who criticises the inexistence of a centralising figure in the former team, who "would know how to distribute the work".
Chief inspector Antonio Teixeira and inspector Portel, both from the Lisbon Directory and homicide experts, are two well-know names in a team that includes another four investigators (from robberies and data crossing departments). "They are reviewing the process. There was a lot of important information that was despised in the investigation", the same source says.
