@Madison5716 I don't get here very often, so just seeing that I was tagged now. To answer your question, my study is the place to send any potential physical samples. Jeff was sending samples to me before he passed, and every biological sample he still had in his lab that folks had previously sent to him is coming to me at NC State.
The link to offer samples is the first button/link on this page: https://sites.google.com/ncsu.edu/darbyorcutt/home
Unfortunately, Henner passed very soon after Jeff. He was a big supporter of my work too, and both he and Jeff were eager to see what my findings would be.
