Don: That is a very good question, and one that I also would like to see answered. You and I differ on just how important the Ramseys were in this (that is, how "intense" the interest was), but even in my scheme here, there is some particular reason for picking them. My first guess regarding this reason would be that they were people of some note in Boulder so that the case would attain some magnitude of popular interest, increasing the likelihood that the message would be heard. My second guess is that he actually was familiar with the Ramseys.
