Firefighters spent an hour Tuesday morning searching for a man who reportedly fell into the Spokane River near the Post Street bridge. Crews responding to a 911 call shortly before 8 a.m. found a man on the bridge who was disoriented and hypothermic, Battalion Chief Craig Cornelius said. The man said he and a friend had fallen into the river just above the hydroelectric dam near the Washington Water Power building, but firefighters found no sign of a second man. “He said he had a friend that went in the water last night,” Cornelius said. “There’s no indications at this time that we have anyone in the water.”
