Why are there so many oddities surrounding the alleged double-murder suicide?

>Benoit's wikipedia page was edited to say his wife was dead hours before the police knew about the bodies
>Dave Taylor and his wife were seen walking towards the Benoit home with a plate of food on the day Chris and his family were found dead
>Nancy was planning a small party because Hardcore Holly was supposed to visit that weekend but he backed out for some reason
>Regal was frantically calling his wife on the day Benoit went missing, as he lived in the same neighborhood, and thought someone was targeting wrestlers
>Both Hornswoggle and MVP have expressed doubts about the official story
>A kitchen knife was found under Daniel's bed but not used in the murders
>Benoit was paranoid to the point where he was taking alternate routes home and believed he was being stalked
>Benoit's former tag team partner, Biff Wellington, was found dead on the same day
>Empty bottles of alcohol discovered near Chris but the autopsies didn't find alcohol in anyone's blood
>Benoit, for some reason, was texting his address to close friends who already knew where he lived
>Verizon wasn't able to retrieve any info from Chris and Nancy's phones due to a technical error
>People like Meltzer, who normally defer to the police when they're involved, admits there are inconsistencies surrounding the case

The official, publicly available, records don't match up with the mainstream narrative at all but it's readily accepted that Benoit, with no history of violence or mental illness, decided to kill his family. No official motive has ever been presented and people who were close to him, like Chris Jericho and Vickie Guerrero, can only speculate. It's all a bit strange.
