Toni Henthorn was pushed off a cliff by her husband in Rocky Mountain National Park. There were no witnesses, but the federal government was eventually able to build a circumstantial case that was sufficient for a jury to convict. It helped that there was financial fraud and a longstanding pattern of deception on the part of the husband. In fact it looks like the husband may have also killed his first wife for the insurance money.

If the allegations are true in this case, I suspect that money will also be at the heart of it. I don't know if Arizona will be willing to put the same time and effort into building a case like the Feds did, but I just wanted to point out it's not impossible to get a conviction if he really did push her.
Edit - Another similar case was the murder of Cody Johnson by his newylwed wife, Jordan Graham. Her motivation was unclear. It seems she may have had a fear of sex, but was pushed to marry because of her religious upbringing. She just told a multitude of lies, which allowed the police to eventually confront her and get a confession. Weird case.
