I haven't been keeping up with the Somer Thompson case, but as I recall shortly after her daughter died, she went on TV and warned the killer that he WOULD be caught. She seemed to be in the anger phase, which seems pretty normal. The case with Marc Klass's daughter happened many years ago, but as I recall he wasn't advocating forgiveness so soon after his daughter's death. His reaction also seems normal to me.
BL's reaction seems abnormal to me, because there is no anger and he doesn't even seem that upset about what happened to his daughter. I am not saying he should be raging like a lunatic, but he seems too eager to forgive and accept what happened to Shaniya.
