PLUMMER, ID -- Last week, a man died of a heart attack in the sauna of a wellness center in Plummer, ID. His body was discovered the next day.

A maintenance worker found the body of Thomas T. Dodge in the sauna of the Coeur d’Alene Tribal Wellness Center nearly 10 hours after Dodge had checked in on Oct. 20, according to the Spokane (WA) Spokesman-Review.

Dodge, 66, apparently tried to stand up from a bench when his heart problems began, but he collapsed and likely died instantly, Benewah County coroner Ron Hodge told the newspaper.

Marc Stewart, a spokesperson for the wellness center, told the newspaper that closing procedures at the center require a walk-through to make sure no one is in the building.

“When they closed the center, they didn’t see him,” Stewart said.

The center’s employees will decide whether to change their procedures after an investigation, the newspaper reports.
