A 21-year-old Howell woman was killed early Thursday when her car crashed into a tree north of Standish.

Arenac County Undersheriff Don McIntyre told the Arenac County Independent that McKenzie Gibbon of Howell was driving a Mercury Milan on I-75 and according to the initial investigation, she either fell asleep or lost consciousness before leaving the roadway and crashing into a large tree in the median.

McIntyre said the crash, which was reported at 3:12am, remains under investigation. (JK)
