Since the woman had a single gunshot wound and the gun was lying near her, maybe it will turn out to be a murder-suicide.

Considering they were seen driving in an Esclalade that was registered to both of them. I am more inclined to guess that she was more than a friend who decided she didn't want to share with the wife.
According to reports police aren't actively looking for suspects which would indicate murder/suicide.
Really sad, in that, the wife and kids are left guessing and to pick up the pieces.
