You've got to ask questions about the Portuguese Police! For them to turn round 3 months after the event and say "oh, by the way, we've now found blood on the walls" seems to be a bit of a shambles if you ask me. Not that we have the best police force in the world, but I'm sure even PC Murdoch fae Oor Wullie would have found blood on the walls of (currently) the most famous crime scene in Europe.
Also hard to fathom out why, if she's a suspect he isn't? Put it this way - you and your partner are on holiday with 3 kids under the age of 4. You're in a strange place, and you somehome manage to murder your 3 year old daughter, and dispose of the body without your partner knowing anything about it, and also somewhere that a huge manhunt could not discover???? I can't imagine that this is something you would/could do on your own, without your spouse knowing. If he's not a suspect, I don't think she should be, and if she's a suspect then he should be, if you catch my drift.
I might be being incredibly naive here (obviously having never been in the situation myslef) but I think a parent would know if their partner had murdered their child. So, stating the bleeding obvious, she's either guilty and the world's best actress or innocent and justifiably distraught at being named a suspect.
The more I think of it, if she had done it, they would have uncovered something long before now, but only time will tell.
All this just when you thought it was dying down as well!
All definitely a bit strange
