Actually, I don't think those sketches were made by Scotland Yard.  The McCanns hired a private investigation firm to look into things, I believe they commissioned the sketches.  The head of the firm was later convicted of being a con man....even faked his own wedding.  He had a reception and everything, kept all the gifts, but the priest was an actor so they never actually got married. The sketches are said to be of the same man.  Two witnesses giving two different looks for the same guy.  A guy much younger than the Podestas.  He was described by the witnesses as white, aged between 20 and 40, with short brown hair, of medium build, medium height and clean shaven. https://www.theguardian.com/uk-news/2013/oct/14/british-detectives-efits-madeleine-mccann-suspect  The investigation firm commissioned the efits.   They were created 6 months after the incident under the direction of Henri Exton who was ex -MI5 and not the conman who headed the investigation firm.  For some reason, the McCanns chose not to use these.  In 2008, the McCanns used money from their charity fund to hire investigators from a firm called Oakley International, led by  former MI5 surveillance officer Henri Exton, to look into the mystery – and they focused on the Smith sighting. They produced a dossier and called for the E-fits to be published. They also suggested Madeleine could have died after wandering off. The McCanns, who became embroiled in an unconnected financial dispute with Oakley International at around the time they received the dossier, responded by warning the detectives of legal action if they publicised their report. A source close to the fund said the report would have been ‘completely distracting’ if it had become public.  https://www.dailymail.co.uk/news/article-2478087/Why-Madeleine-McCann-suspect-E-fits-kept-secret-5-years.html
