It is obvious that the ransom note author disguised his or her handwriting. Therefore, it is obvious that the ransom note author acknowledges the risk involved in leaving the ransom note. In Radiology we are often faced with the risk/benefit question. In mammography screening, for instance, we must consider if the benefit of possibly finding an early breast cancer on some patients exceeds the risk of exposing many patients to radiation exposure. The American Cancer Society and the RSNA has concurred that the benefit outweighs the risk. We humans utilize this benefit/risk equation on a daily basis. Does the benefit of getting to work outweigh the risk of getting in an automobile, for example. The ransom note author took a risk by writing that ransom note. The author's attempt at disguising his or her writing speaks loud and clear. Therefore, the ransom note author perceived he or she would gain some benefit by writing that note and that benefit far outweighed the risk involved. Thus, we must ask ourselvs who would receive a benefit from writing that note. I'll list the most obvious. 1. The parents. If they were somehow guilty, they had a dead body they had to try and explain. 2. An acquaintance who wanted to frame the Ramseys. 3. An acquaintance enemy who wanted revenge on the Ramseys. This is similar to # 2. No one else would even remotely receive a benefit which would justify the risk. Which of the two, above, gained the most benefit from the ransom note. An acquaintance only had to molest and kill the girl, leave no fingerprints or other evidence, and get out. The Ramseys would have been main suspects. Yet, the ransom note might have added more suspicion. Would this benefit outweigh an acquaintance's risk? The benefit for a Ramsey authorship is that they could draw suspicion on a host of other suspects, cause confusion, allow them to bring other people into the crime scene, allow police to find the body, etc.etc. Would these benefits outweigh the risk of being identified as the author? I think it is obvious who had the most to gain by taking the risk of authoring the ransom note.
