What happened?? Missing faces...

My friend and I were having a pre-Olympic gymnastics watching party from all the 2016 US comps, and following the ranch documentary we were filled with questions about missing faces. Can someone fill us in on what happened to:

- Madison Desch
- Norah Flatley
- Bailey Key
- Jazmyn Foberg(??)

Thanks in advance.
