Ummmm, Yes I can, and I would definitely not be supporting my murdering daughter. It would be tough love and cutting her out of my life!
Other parents of murderers such as Mark Hacking's parents, Jeffrey Dahmer's father, and Ted Kaczinsky's brother didn't lie and cover-up for them. They took responsibility, turned some of them in, and apologized to their victim's families. That's doing the right thing, not unconditional family love and support at any cost. Scott Peterson's parents are a prime example of that, and I believe the Anthony's are acting much like Jackie and Lee Peterson!
