'I ended up cooking her,' chef said of his dead wife

I think this guy, David Viens, 49, who boiled his wife for four days, should be given the sentence of life in prison. he claimed to of duct taped her face, tied her hands and feet and left her like that overnight. In the morning when he woke up she was dead, so he says. The forensic people dont know what initally caused her death because of what he did with her after he died. If he would ammit to something like that then he should be punished, no matter what else he says.
