Police in Juneau, Alaska, said they were investigating the death of Stephen “Greg” Fisk, the city’s newly elected mayor, after he was found dead in his home on Monday.

The Juneau Police Department said that Fisk’s adult son called 911 shortly after 3:30 p.m. Monday to report that he had found the mayor there, drawing police and fire officials to a home at the end of Kennedy Street in the state capital.

Fisk, 70, was pronounced dead at the scene. Authorities say it will take several days for the autopsy results to be released and determine a cause of death.

In a second statement late Monday, police said they are “aware of rumors that an assault occurred in connection with Fisk’s death” but did not suggest that any rumors have been confirmed.

“Those rumors are speculation,” the statement said.

Detectives with the Juneau Police Department are investigating the case, while the medical examiner’s office will conduct the autopsy.

In a statement Tuesday, the city assembly said it was “deeply saddened by the loss of Mayor Greg Fisk.” Mary Becker, a second-term assembly member, has assumed Fisk’s role, the statement said.

Fisk was elected to office in October, ousting incumbent Merrill Sanford to become the leader of the state’s third-largest city. His term ran through October 2018.

He moved to Alaska in 1959, the same year it became the country’s 49th state, according to his campaign Web site.

Alaska Gov. Bill Walker said in a statement that Fisk would be “remembered for his dedicated service” to the city he served.

Sen. Lisa Murkowski (R), who said she was raised in Juneau and other cities and towns in the state, also offered condolences on Tuesday:
