This morning a 15-year-old allegedly stabbed and killed a 17-year-old and critically injured an adult man and two other children in his foster home.  It's not the kind of thing that happens around here very often.  I think this is the first time that I've read a story like this in the local newspaper (link) and paid attention to the "Reader Comments" section.  It's very strange...comments from the biological mother of the victims, from friends of the alleged murderer, etc.
