"The NIHF has received the news that the promising 23-year-old Scott Winkler has been found dead in his home today. Our deepest condolences to his family and friends," the Norwegian Ice Hockey Association announced via its Twitter account.
Winkler, a third-round draft pick of the Dallas Stars in 2008, had been playing for the Colorado College Tigers as he combined ice hockey with his recently-concluded studies.
"The Dallas Stars are heartbroken to hear about Scott's passing," Dallas Stars general manager Jim Nill said. "Scott was a wonderful young man with great character and a bright future."
Asked about the cause of Winkler's death, a police spokesman told Reuters by telephone: "It is too early to say yet, but there is nothing to suggest any crime."
The police will release a statement early on Friday.
