This is a senseless statement. Routier was convicted, not by the "life experiences" of a commentator on an Internet message board, but by a jury of her peers in accordance with the laws of the state of Texas.
In that case it is people like YOU who refuse to see facts, and would rather fit the facts to your own prejudices. There's nothing wrong with doing that (so long as you aren't in a position of authority), but I think you ought to know that your opinion is worth no more nor less than anyone else's, but it is NOTHING next to the deliberations of our legal system.
If twelve good men and women found her guilty beyond a reasonable doubt, that is MORE than a preponderant weight against her. She has had her day in court, and she's working out her legal options now. In the end, if she dies for this crime, it will be because she did the murders.
And this is written in stone where? Several jurors in Routier's trial now believe she is not-guilty. "Evidence" was presented in a misleading fashion.
