Now how does Amaral end up being dragged into this thread? Obsessed, some people are!
Have you actually been discussing the same case as everyone else. If you were I think you would probably recognise that Amaral was an influence from the start.
Remember one Christian Brueckner who the PJ tried to interview, but who dropped off the radar when he didn't answer the police knock on the door. That was on Amaral's watch - but he was far, far too busy leaking disinformation about "badly told stories" tempered with misinformation about Calpol, an over the counter child's analgesic being a dangerous sedative.
Of late Amaral has done everything possible to wreck the German investigation into Brueckner who is their prime suspect by leaking his details on Saunokonoko's podcast prematurely then releasing disinformation about that.
So the guy who was on police radar during Amaral's watch but who couldn't be found despite apparently still living openly in Luz when and after Madeleine's disappearance, was able to use any one of his distinctive vehicles to saunter off to Germany without a backward glance.
If anyone can be classed as having an obsession that person is Amaral who was still casting slurs at Madeleine's father while championing the innocence of a paedophile and rapist who is prime suspect for three national police forces..
