A Fort Wayne man was in critical condition after being thrown from a snowmobile on Hamilton Lake.
Indiana conservation officers were called to the 400 block of Lane 210 in Hamilton at 4:50 p.m. Monday.
Officers said Hayden V. Rice, 28, was operating a snowmobile on the ice on Hamilton Lake at a high rate of speed when he did not make a turn, was thrown and struck a metal dock post.
Rice was flown to a hospital in critical condition with multiple broken bones and internal injuries.
Rice was not wearing a helmet or any other protective gear, conservation officers said.
The investigation is ongoing.
