What mode of transportation did JAR & sister use to head back home from Colorado? Could they have supposedly left but came back to carry out the plan of the note/crime? Is there a possibility that their mother lied for them? I read the ransom note several times and still come up with the following theories: 1) That PR wrote the note to cover for one of the Ramsey males. Perhaps she and John assumed Burke did the crime and they put a plan in action to cover for him. 2) That two people (a male and a female) committed this crime. Perhaps JAR & sister?
