Exactly. Any competent civil attorney would have a jury wanting to hang the Van Dam's. Danielle's murder would become nothing more than a means to explore the VD's private life, and THEY would become the focus of any civil proceedings. IF DW were found not guilty, and they tried to sue him for wrongful death, he would countersue, and stand at least as good a chance of winning as they did. The VD's would be much better off to just fade away, and let the criminal trial decide Westerfield's fate. Of course, they have shown they aren't the shaprest knives in the drawer, so who knows what they'll do?
Watch your hose,fibers,and never leave the neighborhood when someone has gone missing,even if you aren't aware of their having gone missing.
