It was a deadlier Memorial Day weekend this year than last. Preliminary reports sent in to Michigan State Police show 15 people were killed in 11 separate crashes, up from 10 dead in 10 crashes in 2017. Of those wrecks, alcohol was a factor in two, and five involved motorcycles. One of the people killed was a pedestrian. State police say the numbers could still go up, as those figures are only what had been reported to them as of yesterday morning. The holiday weekend ran from 6 p.m. Friday through 11:59 p.m. Monday.
