I walked in an autism walk a couple of weeks ago, and met a number of advocates working in the autism community. Many of the walkers were parents. But, as far as I know, none were parents of a murdered child.
This story out of Iowa is a very humbling story.
The fact that these parents, in tribute to their murdered daughter, would embark on this type of walk, is mind boggling.
Every time you lose your faith in humanity, something like this restores it.
