The death of legendary mixed martial arts head coach Robert Follis has been ruled a suicide by the Clark County (Nev.) Coroner, a spokesperson from the coroner’s office told MMA Fighting on Monday.

Follis, the former coach at Xtreme Couture and a founding member of Team Quest, died Friday of a gunshot wound to the head, the spokesperson said. The place of death was Nevada State Route 160. Follis was 48 years old.

News of Follis’ unexpected death surfaced Sunday and with it came an outpouring of emotion from the MMA community. Dozens of Follis’ friends, colleagues and fighters took to social media to remember his life and mourn his death.

Follis’ girlfriend Myra Fukuno wrote Sunday on Facebook that the Follis family would need “considerable” time for privacy. But she shared an email address where people can send memories, stories and photos of Follis: robertfollismemorial@gmail.com

“If you have a story about him or pictures you would like to share, please do so here so that all of us can may visit different parts of his life,” Fukuno wrote. “If you would like to share something more privately, I’ve set up an email address that some family members will be able to access. Stories, photos, etc are welcome. We may not be able to respond, but please know that we will sort through them as part of our healing process. Thank you for your patience and understanding. Memorial service information will follow at a later time.”

Follis was the head coach at Xtreme Couture for the last four years, guiding the likes of UFC fighters Miesha Tate and Kevin Lee, among others. He departed the gym earlier this month, with plans to open his own facility. Follis was a co-owner of the legendary Team Quest, along with Randy Couture and Matt Lindland. He spent 10 years at the Gresham, Ore., powerhouse gym.
