The incident unfolded in Eagle, Idaho, where the Nampa mayor suffered what officials initially described as a "medical emergency."
Fellow mayors and emergency responders rushed to help, but despite their efforts, Hogaboam could not be saved.
In the days since, officials have confirmed the cause of death.
Mayor Death Linked to Rare Cardiac Condition
The Ada County Coroner determined that Hogaboam died from "cardiac tamponade," a serious condition involving fluid buildup around the heart.
According to the Cleveland Clinic, the condition can affect people of all ages, though it remains relatively rare.
Roughly two out of every 10,000 people develop cardiac tamponade as a result of other illnesses, including cancer, infections or trauma.
"Cardiac tamponade describes a heart that has so much fluid around it that it can't pump enough blood," the clinic says. "The force of this fluid makes it hard for your heart to do its job. This is a medical emergency."
"A healthcare provider has to remove the extra fluid with a needle or surgery. You need quick treatment for a good outcome."
The emergency occurred around 6:45 p.m., with Eagle Mayor Brad Pike, who was seated next to Hogaboam, among the first to notice something was wrong.
Pike, a former firefighter, quickly stepped in and "immediately responded to Mayor Hogaboam by administering CPR."
Staff from the Treasure Valley Partnership called emergency services as the room was cleared and the meeting was adjourned.
Community Mourns Sudden Loss as City Prepares Next Steps
Despite extensive life-saving efforts, Hogaboam died at the scene.
Officials noted that he was new to his role as mayor and had previously served the city of Nampa and Canyon County in various capacities.
"It is with the deepest sadness that we must report Mayor Rick Hogaboam experienced a medical emergency tonight. And has passed away," his office said in a statement. "We ask the community to please keep his family and loved ones in your prayers during this incredibly difficult time."
"As we begin to mourn this unbelievable loss, please provide grace. While we navigate the loss of not only our Mayor. But also our friend."
According to KTVB, city officials are expected to meet in the coming days to determine the next steps following Hogaboam's sudden passing.
A spokesperson said the city council president will serve as acting mayor until a permanent replacement is appointed.
