Cerebral Palsy can be very devastating to the afflicted and to the parents & families. I could see the killing being an act of mercy in the mind of the younger sister, if her sister was very, very sick. This is a tuff one, and because it has medical complications mixed in it, we may not find out much more about this one. And those poor parents -- both girls lost to them in such tragic and heart-ripping ways. What will they do tomorrow -- find an attorney for one daughter or find an undertaker for the other? Or both. Oh my, it takes my breath away.
