NIPIGON, Ont. - A snowmobiler has been found dead after his machine went through the ice on a lake in northwestern Ontario last week.

Ontario Provincial Police have identified the dead man as 51-year-old Gerald Thompson of the Rocky Bay First Nation.

They say the search continues for a second man, Nathaniel Thompson.

Police say they were contacted on Friday about the two men, who were last seen on Lake Nipigon on Thursday.
