Sadly, I haven't been able to find a link to a site with the full
narrative of this story, but I suspect it can be pieced together from
what's on the web:
Cynthia George was a beauty queen who married well, had several
children and two simultaneous affairs. One of her lovers murdered the
other.
Dateline did a show on her case. It's got a fair number of twists and
turns and raises some interesting legal issues. Here's the blurb.

I feel a bit silly putting in spoiler space for something from 2007
but it might be better, if you can see the Dateline show, to not know
how it turns out.
She was tried for the murder too, and elected to be tried by a judge
not a jury. The judge convicted her and an appeal court overturned
the conviction. The family of the murdered lover is bringing a
wrongful death suit against her.
