Scott Coville disappeared from Sitka, Alaska back in 1988. Early this year, his wife Jane (referred to in media accounts as Jane Limm or Jane Reth) was charged with his murder. Well, this article from the Anchorage Daily News is all I can find: as of last week, Jane has agreed to plead guilty to second-degree murder.
The sentencing hearing is in late November; Jane could get up to 99 years in prison. Hopefully more info about the case will come out then; I don’t have many details.

She ought to have to cough up the body to not get fried. What a Charlie Foxtrot. I’m actually surprised she plead at all.
She received a sentence of 36 years.
