I do not care about Levi Aron's messed up childhoocd or mental problems. His crime is so heinous he deserves to die. If he spares the family a trial and pleads guilty life in prison with no parole is acceptable. Prison justice will probably be far worse than a lethal injection.
As far as molestation the evidence of molestation is inconclusive.
Perhaps the large scale searches are a bad idea. More erffort should be made to let jerks like this know they will be found and if they return the kid now they may get out in ten years if the kid is unharmed.
