Tyler Duckworth, a two-time winner of MTV's reality competition series "The Challenge," has died at the age of 44. The US Sun reported Thursday that North Dakota officials confirmed Duckworth's death, which occurred on Tuesday. Officials classified the case as an unattended death, meaning no witnesses were present at the time of discovery. Duckworth was found unresponsive in a bathroom. An insider told The US Sun that Duckworth had recently undergone surgery, though it remains unclear if this contributed to his passing. Paramount, the network behind "The Challenge," has been contacted for comment. Duckworth was known for his appearances on the long-running reality show, where he secured two championship titles. His death was first reported by The US Sun.
