Weird, according to Google, my dad lives FOUR minutes away from these people! Creepy!
As for the LDS, I have extensive experience there, but not necessarily extensive
knowledge about the church. I know there are two kinds of marriage and divorce. There's earthly, justice-of-the-peace, death-do-we-part marriage, and then there's temple marriage, which is "for time and all eternity," meaning you're still married to them after one of you dies (and oh there is so much more story involved in that, but that's for another time). The ideal is to get legal and temple married both at the same time, but there are cases where a couple will get legally married and then a year later get temple married, or "sealed," in LDS lingo.
Thus, there are two kinds of divorces. There's legal divorce, which is the same thing as it is in the non LDS-world. But, if you've been temple married, and you want to make dang sure the other person won't be hanging around you in the afterlife, OR if you want to get temple married to someone else, you have to get a temple divorce. These are hard to get, I hear, and a Big Deal. But, they do get granted. My father's second wife got a temple divorce because her first husband was a...piece of fecal matter...and beat her up.
Either kind of divorce doesn't mean an automatic excommunication, though. There's a whole...process and if someone is appropriately repentant and jumps through all the presented hoops, then you're cool.
Killing your wife on purpose, however, is pretty much grounds for immediate excommunication. And an automatic temple divorce, too, I would assume, but you'd have to ask the big guy on that one :angel:
I'm very interested to see how the TOD and more info. comes out here on this one. Yeah, the Hacking case definitely comes to mind.
