Michigan State Police said at least eight people were killed in seven separate traffic crashes during the Labor Day holiday weekend.
Four of the eight victims were not wearing seat belts, and alcohol was a known factor in three of the eight fatal crashes, state police said.
"These numbers are preliminary and only reflect those fatalities reported to the MSP as of noon today,' Capt. Harold Love, commander of the state police Traffic Safety Division. "The preliminary numbers show a decrease in fatalities from this same holiday period last year.'
