Emergency medical services workers in Big Rapids were responding to a report of a deceased person when they found Nicholas Suttles about 8 a.m. Friday with an irregular heartbeat and suffering from hypothermia. He was flown to a Grand Rapids hospital for treatment.
Authorities believe Suttles may have spent about five hours in the snow. He was not wearing a coat.
They said it appears he took his own alcohol to the party and drank a large amount.
Police are reviewing surveillance video from businesses in the area to see how Suttles ended up in the snow bank.
