My gut reaction as a parent is that he should be put down like a rabid dog. The story upset me pretty badly - why so much detail leaked to the press before the trial? I usually do not advocate for the death penalty, but am probably too upset to form an un-emotional opinion on this one. The most important point (IMHO) being that at least they caught the guy before he picked up someone else AND that he never be allowed the opportunity to do it again.
