I just dare to hope those poor children just died in their sleep of smoke inhalation, and never felt a thing. I can't believe this has happened. I also hope the person who did this is now in a state of total guilt and horror, and will give him/herself up as soon as possible. I could not stop crying looking at some of those links. So, so sad that a family has to go through this, and that it's all due to the sick actions of one person.
