Heriberto knew about them in 2013;
The 74,104 phone calls were the recorded ones activating BTS or retrasmitting antennas at Praia da Luz, on 2, 3 and 4, May, 2007, by mobile phones of the three Portuguese companies: Optimus, TMN and Vodafone.
The following table shows the distribution of the calls by day and by phone company (click to enlarge). Data were obtained from the Polícia Judiciária files on the case (2007-2008).

So the only reason OG and the Germans have those phone records to consult is because the PJ obtained them for future feference.
Having apparently gone to that bother ... don't you think it was remiss of them at the time not to analyse the phone data beyond the phones of the McCanns and their friends ~ Murat and his friends ~ one or two Ocean Club employees whose statements caused concern?
The information the Germans used shared by Scotland Yard was all there in Portuguese hands back in 2007 ... a little action such as that expended on on Madeleine's parents might have gone a very long way.
SnipLaw enforcement agencies in 30 other countries - most of them in Europe - have also been asked for their assistance, principally to trace people thought to have been in Praia da Luz at the time.
Speaking to the BBC's Today programme, Peter Sommer, an expert on cyber security, said the "multi-jurisdictional nature" of the case, which would involve mobile phone companies in different countries - and the gap in time - could make it harder to track people down.
But he said "cell site data" was routinely used in most criminal court cases in the UK.
Mr Gamble said the EU data retention directive, which compels telephone companies to retain call and internet records for a period of time, was at an "immature stage" in 2007.
But he said it appeared the data "wasn't properly or appropriately interrogated," at the time.
In UK investigations, he would expect the data to have been examined almost immediately, he said, but the "complex nature and geography" had made it more difficult.
