Of course his sister don't want it to be him and live in denial. It looks as if he was not worried at all that people would be coming and going in the house, and garden, and basement.Going through the timeline on the wikipedia page - figuring out the last sightings of Agnes there maybe Xavier killed Anne and Benoit on the Sunday night (the 3rd) Then Arthur is the one who is drugged at the restaurant on the night of the 4th and killed that night. Xavier Dupont de Ligonnès, suspected of ruthlessly murdering his wife and four children four years ago before disappearing, has apparently contacted the French press stating, “I am alive”. !I’d love to see a side by side picture of him with the surgery to see how far he went to change his appearance.This is a HUGE twist. She was seen walking the dog after the 4th April, and was also seen with Anne and Bertrand, the two youngest kids.I wonder if maybe she was in on her husband's plan. This is all speculation but, I wonder if he excused not killing himself because he wouldn't be allowed into heaven and that would be the only way to see his family again.Perhaps he is in the run after all.I could go on, but I’m tired and losing interest.Look at the whole picture. I think he's planned this so well he had an escape plan. We'll never know. That makes a bit more sense to me. They kill their families for only a few reasons, either to spare them the embarrassment of finding out that they are massive frauds and haven't got any money, religious reasons (you are all spawns of the devils now you are reaching your teen years. I've seen a lot of families in denial, but their theory is very next level denial!Thanks a lot for your detailed reply !The autopsy seems botched. He probably had money put aside for him to start a new life somewhere and documents to do it. It was never analysed by police to see if it really came from him.None of the cases are my favourites, they are horrible. The last sighting of Agnes was the 7th - so let's say he killed her on the night of the 7th. That would be insane.I still think he killed them and then either killed himself or disappeared through Italy. It is totally normal. I can guarantee that any dates that didn’t work with majority evidence or that threw the timeline out would have been investigated and either cleared up as an error or the timeline adjusted.Thomas was seen on the 5th - he spent the time with his friend - that night he father messages him to come home - the messages after that could have been written by his father - so that would put his death on the night of the 5th or even the 6th. Probably because I'm french and yet have never heard of the story. This was one of the most baffling crimes in French history. Devastating. Xavier Dupont de Ligonnès was the son of Bernard-Hubert Dupont de Ligonnès, an engineer with a degree from the École nationale supérieure de mécanique et d’aérotechnique in Poitiers.
Despite having an altered appearance (plastic surgery) and a fake passport, his fingerprints matched those on file. Assuming it was definitely Xavier. He supposedly sent a letter saying he was a secret agent and his family needed to go undercover in America to try and cover his tracks. He is truly an evil man.The following few days Agnes is in regular contact with the kids' friends who are worried about their absence. Xavier left detailed letters to his family about what to do with the house, their belongings, the contracts, etc. I'll add them in the comments if you're interested.I really like this one because I wouldn’t be surprised if it ends up solved now. No idea how LE could have been so mistaken and how such misleading information could be leaked to the press. Me and the wife were sure he was dead, really unexpected he was finally caught. He will be hiding out somewhere cursing the fact that this aired on Netflix. Still wouldn't explain the lack of dogs, but maybe they were still alive then.It's true that the police could have had the timeline wrong and the murders happened over the course of several nights. It was just speculation.On the other hand, it seems the fingerprint matches only 5 points on 13. I wonder if the sighting of Thomas and his father in the restaurant on the 4th where Thomas supposedly became unwell was actually Arthur or even Benoit?
