News of the accident has sent shockwaves through the Survivor community.

“Caleb was an amazing man and friend,” fellow contestant Aras Baskauskas tells PEOPLE. “One of the sweetest and most sincere humans I’ve ever come across. I am gutted by his loss. My thoughts and prayers are with his family.”

Adds Sabrina Thompson, who competed on Survivor: One World with Cumbie: “While playing Survivor with Colton, he would talk about his boyfriend, Caleb, around the clock 24/7. Within seconds of meeting Caleb at the finale and Survivor events, it’s no wonder why he raved about him. You were instantly drawn to his big smile, warm spirit and Southern charm. May God rest his soul gone too soon.”

Bankston is the third Survivor contestant to pass away since the show premiered. In 2010, Jenn Lyon, who placed fourth on Survivor: Palau, died after a six-year battle with breast cancer.
