Stephen "Greg" Fisk was found dead in his home on Monday afternoon, just weeks after winning the election to become the mayor of Alaska's capital city.

Police say that the body of the newly elected mayor of Juneau was discovered by his adult son, who called 911 around 3:34 p.m., local time, on Monday, reports NBC News. The 70-year-old official was then pronounced dead at the scene.

Fisk's shocking death has sparked a flurry of rumors that he was assaulted. However, the Juneau Police Department dismissed the rumors as "speculation," reports CNN. The police department also said, "Detectives are actively investigating facts of the incident, and all evidence is being preserved and documented."

Chief Bryce Johnson told the Juneau Empire that Mayor Fisk did not commit suicide and there were no signs of forced entry into his house. However, police have not disclosed any other information regarding his death or whether it is considered suspicious. An autopsy report is expected within several days.

In October, Fisk began his first term as the mayor of Juneau, which has a population 32,000 on Alaska's southeastern panhandle. The term was scheduled to end in 2018.

He said his top priority as mayor was to diversify the economy.

"He had great ideas about moving Juneau forward," Juneau assembly member Maria Gladziszewski told the Alaska Dispatch News. "It's just shocking and a tragedy that he won't be able to do that."

Fisk was also a former fisheries specialist for the state's commerce department and a longtime civic activist.

Deputy Mayor Mary Becker, who is now the acting mayor in the city, told NBC station KTUU of Anchorage that the news of Fisk's death was "devastating."

"He was a wonderful person and a friend, and from the calls I've been receiving tonight, I'm not the only one who felt he was wonderful person and a good friend to Juneau," Becker said.
