State Police responded to an early-morning single-vehicle rollover accident along US-41 near the Alger County–Marquette County line.
Troopers from the Negaunee Post say alcohol is suspected as a factor in the accident.
Alcohol was also a factor in two of the 2010 Memorial Day fatal accidents in the state.
Law enforcement in the U.P. and across the country have stepped up drunk driving and seat belt patrols for the holiday weekend.
The official memorial day weekend begins at 6 tonight and runs through midnight Monday night.
Last year, 14 fatal traffic crashes resulted in 15 deaths over the three-day weekend.
Of those who died, three were not wearing seat belts.
