He didn't hire a profiler so he learns more about who might have done it.JD was hired for his defense. He didn't hire PI's to look for the killer.Those were hired for his defense. He didn't stay in Boulder where the cops needed him and his cooperation re who the killer might be.He left town. He didn't put up a 1mil reward,he just offered 100.000,even the "kidnappers" wanted more. They didn't publish the RN in their book ,maybe someone would have recognized the intruder's handwriting,right? He didn't want the body exhumed,who knows what tests they would have done,what else would they have discovered about the killing. He doesn't let his son answer questions,maybe Burke heard something,maybe he even saw the intruder,right? So what EXACTLY did John Ramsey DO to find his daughter's killer? Maybe he did do something and I missed it. He said this will be his mission for the rest of his life.He said he will spend everything he has to find the killer.The only money he spent was on defense lawyers. I know....not ALL parents act the same.....still,what did he do?Except coming up from time to time with some nonemotional ads like the last one.
