A woman in the US is accused of killing her 3-year-old son after running him over with an SUV during a game of "chicken".
Lexus Stagg was seen in CCTV footage driving towards her three children as they ran towards the Lincoln Navigator SUV.
Two of the children then ran out of the vehicle's path, but Stagg's 3-year-old didn't move in time and was struck by the SUV.
According to police, the child was caught under the right tyre. Stagg didn't stop and the toddler was hit again by the rear tyre.
