Authorities haven't determined what caused the crash that killed a 45-year-old Saucier man Thursday.
Coroner Gary Hargrove said Donald Robertson Jr. was traveling east on Landon Road near Gulfport shortly before 7 p.m. when his 2006 Ford Mustang left the road and flipped several times. Robertson was wearing a seat belt and was not ejected from the car.
The Harrison County Sheriff's Office is investigating the crash.
