I don't agree. Like every single person in this forum (that includes you) I am expressing my own person "take on the trial". I am basing my opinions on the same news articles you are. In any "who dunnit" people will opine who may or may not have been the perp. I do not have the definative answer ... nor do you.
Westerfield according to his own account was not swinging or having a sexual relationship with either of the Van Dams. The Van Dams do not claim that Westerfield had a swinging relationship with them.
My statement says that Westerfield in all probablity killed Danielle even though they did not share a common swinging relationship. It sure looks like two unsavory couples living in close proximity.
Do you have information that the Van Dams and Westerfield were swinging together. I have yet to see ANYONE but you suggest this.
Maybe he did it BECAUSE they wouldn't let him play in their sand box?
