According to Cobb Police STEP Unit investigators, Marc R. Ullmann, 44, was hit while riding his red and white 2007 Aprilia motorcycle south on Cobb Parkway near Paces Mill Road at about 9 p.m.
As Ullmann approached the intersection, Demond M. Tate, 28, attempted to do a U-turn in his red 2009 Mercedes C300 on Paces Mill Road to go westbound. Police say this caused Ullmann to hit the driver’s side door of Tate’s car, and the biker was ejected from his motorcycle.
Ullmann was taken by ambulance to WellStar Kennestone Hospital in Marietta and pronounced dead.
Tate was taken to the same hospital with non-life-threatening injuries.
There were no passengers involved.
Sgt. Dana Pierce could not say what specific injury caused Ullmann’s death, but said that from what investigators told him, the motorcycle was “considerably torn up and he died as a result of the severity of the impact.”
Pierce also could not say exactly what charges Tate faces, but that they would be determined after a state-administered blood test is conducted.
“That is a standard procedure for any serious injury or fatality,” he said. “They probably drew blood from him at the hospital.”
Traffic-related charges will be cited as the investigation continues.
Anyone with information about the crash is asked to call investigators at (770) 499-3987.
