It's all too creepy. This seems to be a large, extended family that was targeted. They are warning other family members to be careful. He or they went to 4 houses so they must be familiar with the entire family. OR they looked up the name in a phone book? Might be a random serial killer. Time will tell. It's got to be someone who is caring enough to not kill the little ones. I'm betting a disgruntled family member. Just so sad!
