Friends and reality-TV castmates gathered at Augustana Lutheran Church in Grand Forks, North Dakota, on Saturday to say goodbye to Tyler Duckworth, the "Real World" and "The Challenge" veteran who died at 44 earlier this month.

Duckworth was found unresponsive in the bathtub of his Grand Forks apartment on Aug. 11 after a neighbor reported water leaking through the ceiling below, according to his obituary in the Grand Forks Herald. Police found no signs of foul play or trauma, and an official cause of death remains pending.

Duckworth rose to fame on MTV's "The Real World: Key West" in 2006 before competing across six seasons of "The Challenge," winning "Cutthroat" and, partnered with Johnny "Bananas" Devenanzio, "Rivals" in 2011. Devenanzio shared photos and highlights from Saturday's service on Instagram, set to Coldplay's "Fix You," writing: "Lights will guide you home. And I hope wherever they lead you, you know how deeply you were loved, and how much of you we'll carry with us forever. Rest easy, brother," per TMZ.

Fellow "Challenge" competitor Brad Fiorenza, 45, echoed the sentiment to Variety: "We shared something special being part of The Challenge family." E! News reported that tributes from the wider MTV alumni community continued to pour in through the weekend.

Funeral arrangements were handled by Amundson Funeral & Cremation Service. No further public statement on the cause of death has been issued by Duckworth's family.
