This is a high school with only 250 students total, where CR's girlfriend was a cheerleader AND was in the same graduating class as MT's boyfriend. The two classmates had to know each other, as they both graduated 1 year before MT. Because it would have been the marriage of a HS classmate in a small town, DJ and his girlfriend would have had some knowledge of who CR was. At least a nodding acquaince, if not more from SM.
A very wise lady (who had been through a bunch of scrapes in her life, and who then read about what DIDN'T occur in the newspapers concerning events she had personally been involved in or had observed) once told me to believe nothing that you hear and half of what you read. Just because it appears in MSM or if LE says it to the public dosen't make it so. These are simply factoids, the relative truth and value of which will be revealed with the passage and fullness of time.
