According to the Ada County coroner, Hogaboam died from cardiac tamponade, a rare and life-threatening condition involving the buildup of fluid or blood around the heart that prevents it from functioning properly.
Eagle Mayor Brad Pike, a former firefighter, was among the first to respond, initiating CPR immediately after Hogaboam collapsed.
Police officers, firefighters, and medical personnel also responded to the scene and attempted life-saving measures. Despite those efforts, Hogaboam was pronounced dead at the scene.

Cardiac tamponade is considered an uncommon condition, occurring in roughly two out of every 10,000 people.
According to medical guidance from the Cleveland Clinic, the condition typically results from an underlying illness such as cancer, HIV, tuberculosis, or an autoimmune disorder.
It requires an emergency procedure known as pericardiocentesis, in which fluid is drained from around the heart. Without treatment, the condition can quickly become fatal.
Medical experts note that common warning signs include low blood pressure, muffled heart sounds, and swelling of the neck veins. However, not all patients display these symptoms, making early detection difficult in some cases.
Hogaboam’s sudden death has left the Nampa community and local officials mourning the loss of a leader who had risen through the ranks of city government in a relatively short time.
A married father of five, Hogaboam began his service as a Nampa city councilman before being elected mayor in November, defeating three other candidates.
At a Nampa City Council meeting held Thursday, members paid tribute by placing a vase of flowers at Hogaboam’s empty seat.
“Our hearts are broken, because we wanted to serve with a great man,” Councilwoman Debbie Skaug said, according to the Idaho Statesman.
City leaders now face the task of moving forward while honoring Hogaboam’s legacy. Under city rules, the council has 90 days to appoint a replacement mayor, who will serve until the next scheduled election in November 2027.
Councilman Sebastian Grin also reflected on Hogaboam’s work ethic and character during remarks reported by the Idaho Statesman.
“He had a gift of being able to turn 24 hours into a month, and he did it every day. The best way we can honor him … is just showing kindness to one another,” Gri!n said. “Having more grace with one another, and appreciating the time that we have here. Every day we have is a gift.”
A memorial service for Hogaboam is scheduled to take place at the Ford Idaho Center on March 31.
