The Challenge Stars Who Died: Tyler Duckworth, Diem Brown, More

The death of Tyler Duckworth sent a jolt through the bonded-forever family of contestants who aced The Challenge.

“Absolutely heartbroken to hear about Tyler,” Brad Fiorenza—who teamed with his then-wife Toni Hall, Duckworth and Dunbar Merrill to win the MTV competition’s 20th season, The Challenge: Cutthroat, in 2010—posted on Instagram Aug. 13. “We shared something special being part of The Challenge family. I’ll always be grateful for the memories we shared…Tyler will be deeply missed by so many. May his amazing soul live on in the lives he’s touched.”

In paying tribute, Fiorenza shared a photo of himself with Duckworth and fellow alums Mark Long, Rachel Robinson, Tina Barta and Paulie Calafiore from a recent Challenge Mania podcast event. Duckworth shared the same pic Aug. 2, his final Instagram post.

The 44-year-old’s mother, Joni Duckworth, shared on Facebook Aug. 13 that her son died “earlier this week,” and the cause wasn’t yet known. The Grand Forks Police Department told E! News that Duckworth was found dead in a bathroom of his North Dakota home after they were called to do a welfare check.
