paranoid schizophrenic that was off his medicine and was also a substance abuser? Someone with a history of violence and assaults on children that lived nearby?
I don't see a normal person behind this---that spent a lot of time planning a kidnapping or murder. What was striking to me in the recent Court TV presentation, was once the perp found a way to get into the house, it was only a short walk up the stairs, and the paper and pen were clearly in view. John Andrews bedroom was disturbed, and was right next to JBR's. With hours to spend in the house, it's entirely possible the original motive changed and evolved as he walked around the house.
The garrotte and ransom note were both done with things from the house---doesn't show preplanning for murder or kidnapping.
Not unlike the profilers in the sniper attacks, we may be giving too much credit to the killer of JBR for cunning. He may have carried around a burglary kit......may have been attracted to JBR....but the whole plan evolved once he gained access to the house, and had opportunity. He couldn't take JBR out---and there clearly was an attempt to put her in the suitcase (possibly dead). All of this may be the result of the garden variety paranoid schizo that got an idea....and he's still walking around (unless he's dead).
Gary Oliva told his friend he hurt a little girl....he had the past, and he was in the neighborhood....he supposedly was a paranoid schizo and there are a lot of similarities in his printing to the ransom note. The tapes aired on 48 hours show a very disturbed individual into sick fantasy...who had done prison time for raping/assaulting a 7 year old girl. He didn't get away with it the first time.
