BLAIR, Wis. – A man who died cleaning the bottom of the 100,000-gallon Blair municipal water tank was Carlos Medina, 30, of El Paso, Texas, Sheriff Brett Semingson confirmed. The sheriff has classified the death as accidental even though an autopsy report was pending. It was thought that Medina died underwater of hypothermia, probably entangled in a 90-foot suction hose he was using to suck sediment from the bottom. Life-saving measures were unsuccessful.
