John Watson III has been sentenced to death for the 2006 murder of his wife Everilda Perez Watson, also known as Eve and Evie. Her body was never found. In letters sent from jail, John admitted he cooked and ate part of the body. (The conviction and sentence was actually last month, but I didn’t find out about it till now.)
It seems like the chances of John’s actually being executed are pretty slim, the death sentence non-withstanding. He is currently 70 years old. I think the average wait time on death row is ten or twelve years, meaning he’d probably be at least 80 when his turn comes. That’s assuming he doesn’t decide to waive his appeals and get it over with. Which he just might do; he apparently requested his death sentence.
One article I found says John confessed to raping and killing a hitchhiker back in 1967, but he was released without charge because the police couldn’t find her body. It’s not clear whether this hitchhiker was an identified missing person or not.
