IMO. Something absolutely happened in the house. By who? Whoever was in the house at the time - and that has not been released. I believe I know who though. I do not believe the SM's daughter did anything bad...but I do believe mom has major control over her and the daughter is weak.
I also do not believe the daughter is a USAF Academy student (that was mentioned a lot in thread #2). That is one of the hardest schools to get into - outside of other military schools, such as the Navel Academy. My husband is an AF vet of 16 years. And we are in Colorado. I know the AF life and career. I also doubt she is active duty. Maybe she joined, but has not left for bootcamp yet. You can join at 17 and depending on the job, may not be able to leave until 18. No way she is active. Even doubt reservist. She may have absolutely no attachment to the AF and is just one of those "maybe I will join" and mom is exaggerating.
Quite honestly, I do not believe a thing SM is saying.
