The evaluation may have indicated a serious problem that required immediate attention? I have been wondering about that. Early 20's is when schizophrenia and bi-polar disorder are often first diagnosed; JM had a known drug problem; and untreated mental illness along with substance abuse dramatically increases the possibility of violent crime. If that is the case, things just became even more tragic for everyone.
I am also bothered about the inconsistencies in this case, the changing stories given to police, etc. I find it hard to believe the police would let blatant and publicized lies slide. Unless something bigger was coming, they were waiting on evidence, etc.
