One person is dead and another injured following two separate crashes on westbound I-69 Tuesday morning. Deputies were called to a rollover crash east of Stapleton Road in Riley Township shortly before 8:30 Tuesday. A truck hauling a horse trailer had lost control on the slippery road and slid into the ditch on the north side of the road, causing the truck and trailer to roll over. The two occupants of the vehicle got out and were waiting for a tow truck, when another vehicle lost control and slid into the same ditch, striking both people standing there. One person was killed when he was pinned between the trailer and the car. The second person standing in the ditch suffered what are believed to be non- life threatening injuries. Deputies are still at the scene of the crash and as of 9:20 a.m., one lane of westbound I-69 in that area is closed to traffic. Emmett Township Fire and Rescue, Michigan State Police and Tri-Hospital EMS are assisting at the scene. No further information is available at this time.
