According to the investigators of the accident, a black 2007 Mercury Milan was traveling southbound on Barrett Parkway at speeds exceeding the 45 mph speed limit. The Mercury, driven by Quan J. Knight, 29,  of Powder Springs, crossed over the center median into oncoming traffic and struck a white 2015 Chrysler Town & Country that was traveling northbound, driven by Donald Ayres, 67, of Marietta.

Knight and Ayres were both taken to WellStar Kennestone Hospital.

Knight’s injuries are serious, while Ayres was treated for non-life-threatening injuries.
