Bring back public hanging. It's quick and it gives people a glimse of what's in store for them. Eliminate the years spent on death row. After the cinviction and a review, carry out the sentence. At high noon!
Bet my next paycheck the husband did it, attempted to make it a murder-suicide but failed. Why else would the "possible murder weapon" be left at the scene.
Looking forward to hearing more about this.
