Two friends were out together today. They were in the willows in front of the headquarters about 200 yds. out and went through. They were in the water a couple minutes, at least. I heard them yelling and started running-walking as fast as I could to help. I was at the "Y" of the slot and the Rookery channel, a little to the north .By the time I got to them two other young guys went through trying to get them out. We got everyone out, and one of the older guys was so exhausted he couldn't get up off the ice.We helped him up, and got him out of his coveralls which know weighed at least 25-30 lbs. They sat there and got their wind back and warmed up some . They both said they were O.K.and could walk back in on their own. By the time I got back to my gear I could hear the sirens coming ,one of the guys called 911 when we were standing there. When I got in , about an hour later they said the one guy wasn't doing too well. He wasn't breathing on his own. I think his buddy said he had a heart condition. This angler did die. DNR has shut down Willow Slough to all ice fishing !!!
