MARENISCO, Mich. (AP) – A 61-year-old Wisconsin man has died in a snowmobile crash in Michigan’s Upper Peninsula.

State police say alcohol and high speed could have played roles in the death of John Riley of Darlington, Wisconsin. He was riding with other snowmobilers Sunday night when his sled hit a tree in Gogebic County, six miles east of Marenisco.

Separately, investigators have released the name of a man who died in a snowmobile crash early Saturday in Houghton County. He was 50-year-old Matthew Heikkinen of Hancock.
