As to your other theory - I really hope you're wrong on that, but there was some reports in the Portugese press last week which mentioned sleeping tablets.

Madeleine McCann overdose claim angers McCanns
From correspondents in Praia da Luz, Portugal

THE family of missing English girl Madeleine McCann are furious after a Portuguese newspaper report which said police believed she was killed by her parents.
The four-year-old's father Gerry was accused, along with his wife Kate, of accidentally killing Madeleine with an overdose of sedatives.
It is 114 days since Madeleine vanished from her bed in the McCanns' holiday apartment in Praia da Luz, while her parents were at a nearby restaurant.
The McCanns, both 39, have remained in the Algarve with their two-year-old twins Sean and Amelie, clinging to the hope that Madeleine would be found alive.
Portuguese newspaper Tal & Qual ran a front-page picture of Mr and Mrs McCann and the headline: "Police believe parents killed Maddie".
Inside, the paper alleged Madeleine died as a result of an overdose of sedatives given to help her sleep, the British Press Association reported.
The McCanns denied giving her such medication.
Tal & Qual claimed Portuguese detectives "are almost absolutely certain that Madeleine was killed by accident by her parents".
The paper attributed its story to an anonymous source close to the investigation and even speculated about the prison sentence someone might get for the crimes of homicide by negligence and hiding a body.
"It's incredibly hurtful and incredibly untrue. Even if somebody could think that, there is just absolutely no evidence pointing in that direction," Mr McCann said.
"Without anything else, what that implies is that we somehow did it, we did it together, managed to dispose of Madeleine without a car, without anything, that the whole group was involved, that there must have been other people involved.
"It is just so absurd, it is just not credible. But we will come through it. We will not stop and it will move on.
My opinion of what happened has not changed in 16 weeks."
Mr McCann attacked anonymous police sources who have been feeding allegations to the Portuguese press, apparently in breach of the country's laws preventing details of investigations being made public.
"I am disappointed that so much information is in the public domain in a country that supposedly has judicial secrecy," he said.
The journalist who wrote the story, Catarina Vaz Guerreiro, said: "I can't reveal my source, but I have complete trust in them.
"I strongly believe the person who told us this information is telling us the truth."
The story was dismissed by Portuguese police.

Father believes Madeleine McCann is in Spain - which is puzzling because firstly they say that they are assuming that she was killed in the apartment and that
"The apartment is the key – all the answers lie there, they say – but they are far from resolving what exactly happened and why the body disappeared."
But...
Police had released the apartment as a crime scene on June 11. It was cleaned and rented out to another family.
But in mid July they returned and then later called in expert help from British sniffer dogs, who detected new samples, which are still being tested. The apartment now lies empty again and has been locked by police.
But all the evidence will have been cleaned away. It just doesn't seem to be a logical investigation, and one wonders if police have been leaned on in some way.
