There are serial killers - people who kill for pleasure. Then there are crimes of passion - the husband who catches his wife in flagrante delicto with the milkman. We really have no idea what kind of killing the Ramsey murder fits into. Many people theorise that a family member did it and that it was covered up. Others believe an intruder did it - but for what reason? Very few child murders happen as a result of a stranger breaking into the home. Fewer still occur on Christmas Day - when people are at home, maybe entertaining friends. Now if JonBenet were killed by a serial killer, perhaps the pleasure factor was so strong that it overruled any natural fear of being caught. However, does it seem likely that such a fearless and perverted killer would resist the urge to do it again .... and again .....? That's 8 years. So if this was a crime of passion - what "passion" would be strong enough for someone to kill a defenceless child? What hatred could overcome the natural urge to protect a little child from harm and to carry out a crime like this in cold blood?
