Susan Leigh Smith (née Vaughan; born September 26, 1971) is an American woman who was convicted of murdering her two sons, three-year-old Michael and one-year-old Alexander, in 1994 by strapping her children in their car seats, and rolling her car containing her two children into John D. Long Lake, a South Carolina lake. The case gained international attention because of Smith's false claim that a black man had kidnapped her sons during a carjacking.
