Officials in Alaska are investigating the murder of Jimmy Gojdics, an avid outdoorsman and television star on the National Geographic Channel's "Ultimate Survival Alaska."

Alaska State Troopers found the 69-year-old reality star shot to death inside in his home on the Old Elliott Highway in Fox, Alaska, not long after 3 p.m. last Sunday. 

According to the Fairbanks Daily News-Miner, Gojdics -- who would sometimes spelled his last name "Gaydos," the way it's pronounced -- was "suffering from apparent gunshot wounds" when troopers arrived on the scene. He was then taken to the Fairbanks Memorial Hospital, where he was pronounced dead.

Since then, his body has been sent to the State Medical Examiner for an autopsy. 

The case is being investigated as a homicide, trooper spokesman Tim Despain told the paper on Monday.

"Jimmy Gaydos ... appeared on the second season of National Geographic Channel's series 'Ultimate Survival Alaska,' airing in 2014," a network rep said in a statement sent to FOX411.

"Mr. Gaydos appeared in the first three episodes of the second season but sustained an injury that made it impossible for his team to continue in the competition."

Although Gaydos did not have any relatives in Fairbanks, his friend, Janine Carlson, said the retired iron worker was a man with many friends.

"Everyone was his friend and he met someone everywhere," she told the Daily News-Miner. 

She added that she knew him for over a decade and that he had a wide-ranging interest in building things like skyscrapers, canoes and rafts. He was also known to drive a Russian Ural motorcycle with a sidecar or a carriage drawn by horses in Fox.

"We were saddened to learn of Mr. Gaydos's untimely passing and our thoughts and prayers go out to his family at this difficult time," National Geographic Channel spokesman Chad Sandhas told The Associated Press on Tuesday.
