I am curious as to why official reports state "non-family abduction" but others here, including at least one here that claims to be related to the family, seem to believe that Edna's brother-in-law, Frank Ryan, may have been involved in her disappearance. I also noticed some older posts from one of Edna's sisters that mentions at least one family member (Frank Ryan?) may have refused to take a polygraph examination.
If Frank was involved, the chances of finding out what happened to Edna and where her remains may be located are likely gone forever and he will never be held accountable. If he wasn't involved, the questions about his involvement will likely continue to shadow his family and it may be impossible to fully clear his name. Although we may never know exactly what was discovered in the investigation or even if all investigative leads were exhausted, this is sad on so many levels - Edna remains missing and likely dead, her family has no "closure" and Frank's family also has no answers.
I would really like to know if there are any family members or friends here that are still able to provide any information that might help close this cold case. This case, and and also Jan Cotta's case, haunt me and are eerily similar - both horse girls last seen at the barn (and if anyone knows horse girls, the barn is where they are happiest and most "at home"), pregnancy (Jan was pregnant and Edna was rumored to be pregnant), both petite girls (Edna 5'1", 105 lbs & Jan 5'4", 125 lbs - while pregnant?), both teens (Edna 15 y/o, Jan 19 y/o) and similar time-frame of disappearance (Edna 6/24/75, Jan 6/26/73).
