The Coroner identified the man as 69-year-old Michael Rhodes of Boise. The cause of death was listed as drowning. The authorities were yet to find out how Rhodes fell in the river. The Garden City Police Department is investigating the death.
Meanwhile, the Boise Police Department, Boise Parks and Recreation, and Ada County Parks and Waterways announced Friday morning that a "Dangerous River Condition" status would remain in effect. The warning means that the officials are cautioning the public to not venture inside the river.
The body of the man was first spotted by the witnesses near the Boise Whitewater Park, not far from East 36th Street late Thursday. Emergency responders managed to pull the body out of the water only after it reached near 41st Street. A rescue boat, jet ski and dive team were required for the attempted rescue.
The rescuers rushed the victim to a local hospital where he was pronounced dead a short time later.
