A U.S. Postal Service worker was killed by her own truck Wednesday in Lyndon Township, Michigan.
Michigan State Police report that after 56-year-old Tracy Sylo left her vehicle to deliver a package to a home, the truck rolled down the driveway and slammed her against a guardrail. Sylo was pronounced dead at the scene, according to the Detroit Free Press.
Police are still investigating to determine why the truck rolled. Lyndon Township is about 15 miles northwest of Ann Arbor.
