Police are investigating the cause of death for Edwards, a former Fargo resident who was crowned Miss North Dakota USA for 2003, reported People magazine.
A police report points out there was no obvious sign of trauma, but the cause of death is being investigated.
The Miss USA and Miss Teen USA organisation posted a tribute to Edwards on Facebook, calling her one of the most "vibrant, energetic, and full-loving" women to ever hold one of the state Miss USA titles.
A GoFundMe page has been set up by Jessica Dereschuk, who won the title of Miss Minnesota USA 2004 and was a close friend of Edwards.
"Samantha Edwards, affectionately known by most as 'Sami,' was one of the most vibrant, crazy, compassionate, loyal balls of energy you could ever come across in life," Dereschuk wrote.
"A conversation with her could either leave you full of adrenaline or utterly exhausted. She was a spitfire and with Sami you never knew what she'd throw your way - but you ALWAYS knew she would be there for you. She was awesome like that.
