In the Gerard Baden Clay case there was a VI who identified herself as living near the family home. She gave great detail about - the police presence at the home and surrounding area, the appearance of the property and what the neighbourhood was like, the search party organised to look for Allison, the terrain and about the site where her body was eventually found.
GBC was found guilty of murdering and disposing of his wife, Allison, currently he's serving his sentence in prison. His lover played a big part in the motive and in the trial, along with a $1 million life insurance policy.
I think CW's AP will play a major part in this trial too, not sure about insurance policy though?
