can you link some evidence that he's a murderer? I'm reading up on it now and it doesn't appear he was ever even a suspect in the murder case from the local authorities.
It's been a couple years since I first heard about the story of him being a murderer and I don't remember what my sources were. Googling is slightly harder because this news is coming to the top for search results. If I sent you any articles it would just be from searching online right now (which you could do just as easily as me), so I'm not particularly helpful here.
Sounds like you answered the question as to by people are focusing on the tax fraud rather than murder.
Maybe for you, but not for me. I really don't care about the ethics of tax evasion when we're talking about a suspected murderer. It's like having a debate about how notorious Al Capone was and only talking about his taxes, because nobody could actually prove anything else the guy supposedly did.
