I just read this on the Green Beret Challenge Facebook page.

"7th SFG brothers and brothers from 1st RGR BN, I just got word that brother Mike Donatelli was killed yesterday while filming a new discovery channel show he was participating in. Mike was residing back in his hometown of Indiana, Pa. I do not have any info on the arrangements as of yet. I will be heading there today and will update accordingly. Speechless... Mike was a very close friend and very important person in my life... Keep his family in mind during this difficult time."
I am sorry for your loss. Mike and his family will be in our prayers.
