I bet with both of these cases friends would talk now. Since they are all grown. I know with the Beatty case it has had some recent media attention. I doubt that Carolyn's case has been relooked at. I wish there was a way to get LE to look again.
There are so many similarities between the two cases.
Kathy was abducted and attacked sometime in the evening of 24 July 1975, the fourth Thursday of the month. Carolyn was abducted exactly four weeks later on 22 August, also in the evening, but it was the fourth Friday of the month.
Kathy was 14, but many later reports state that she was 15 (probably because she would have turned 15 a short time after her disappearance). Carolyn was 15. I do not have very good physical descriptions of either girl, but reports say that both were very good looking with long blonde hair.
The case files both mention "parties" that the girls might have been looking for, and both were outside hanging around with other kids the evenings of their disappearances.
Kathy was living in Aspen Hill, which is just north of Bethesda, Maryland. And Carolyn had recently moved from Bethesda to Moorestown, New Jersey.
It would appear that both girls were or might have been taken away from their place of abduction by motor vehicle. Both were probably attacked within a short time of their abduction. Kathy was left for dead, but lived for 12 more days in a coma before succumbing to her injuries. Carolyn was killed and buried in a shallow grave, where she remained for ten years before discovery.
In both cases, acquaintances were uncooperative with police at the time. Perhaps if police were to dig into their files, locate those potential witnesses and requestion them, more information or clues could be obtained. Maybe information from one case might help in solving the other.
