 JUNEAU, Alaska (AP) — The police chief in Alaska's capital city defended his department's response after the newly elected mayor was found dead at home, bruised and bloodied, and speculation ran rampant as to the cause of his death. 
 
 The speculation was fueled — and the attention surrounding the case grew — when police did not immediately rule out foul play in the death of Mayor Stephen "Greg" Fisk, 70. Police deferred until autopsy results came back. 
 
 Sometimes, it's obvious at the scene that a person died of natural causes. "In this case, we just can't confirm that yet or rule anything out," police spokeswoman Erann Kalwara said Tuesday. 
 
 Fisk's death made national headlines this week and garnered notice far outside Juneau's remote location. 
 
 On Wednesday, preliminary autopsy results indicated that Fisk, who went by Greg, died of natural causes and that the injuries he sustained were consistent with falling or stumbling into objects. 
 
 During a news conference, police chief Bryce Johnson said Fisk had a history of heart problems. He said it's believed that Fisk had some issues with his heart and fell. 
 
 No one had witnessed the death, and when the first person to find Fisk, his son, saw the injuries and blood at the scene "the first assumption was someone had done something to him," Johnson said. 
 
 Police proceeded not knowing the cause and had an obligation to rule out all the possibilities, Johnson said. He said he noted multiple times that it also was possible that Fisk had fallen. But there was a period of time where authorities didn't have answers, he said. 
 
 "And people being people, they run with the unknown for that couple of days, and it's Juneau, Alaska, it's an exotic location. It's a newly elected mayor. And so it was an intriguing story," he said. 
 
 But in reality, it was a tragic story for the family and for Juneau, Johnson said. 
 
 A police statement Monday night, after Fisk's body was found, said police were aware of rumors that an assault had occurred but called those rumors speculation. There was no sign of forced entry into Fisk's home. 
 
 Prior to the autopsy, police also said there was no apparent gunshot wound and nothing to suggest drugs were involved or that it was a suicide. 
 
 Fisk had scheduled appointments Monday and when he missed them, his adult son, Ian, went to his father's home. Fisk lived alone. 
 
 Fisk, a fisheries consultant, was sworn in as mayor in October after ousting the incumbent. Deputy Mayor Mary Becker was named acting mayor. 
 
 Ian Fisk previously stated in an email that his family is grieving privately.

– "The first assumption was someone had done something to him," but the reality is much less nefarious: Juneau Police Chief Bryce Johnson on Wednesday announced that the city's newly installed mayor died of natural causes, reports the Alaska Dispatch News. Though the AP notes Greg Fisk was found "bruised and bloodied," the injuries he sustained—which Johnson specified were on his face—resulted from a fall, not an attack, per preliminary autopsy results. The 70-year-old is believed to have hit a counter and "other objects" as he fell; Fisk was found dead Monday by his son after he was a no-show at morning appointments. Police believe Fisk died that same morning, and while the specific cause of death hasn't been given, Johnson did note that Fisk's health history included heart issues. Fisk had been in the job since October; Deputy Mayor Mary Becker has been named acting mayor.
