ATLANTA (AP) -- Police say the mother of a toddler who died in an unattended SUV in suburban Atlanta told investigators she researched the subject online because she was afraid in could happen.
Leanna Harris hasn't been charged in the death of her son, 22-month-old Cooper. But a search warrant released Sunday says the woman went onto the Internet before the child's death to find out how long it takes for a child to die in a hot car.
Police say Cooper was left in the backseat of an SUV by his father earlier this month. Justin Ross Harris faces murder and child cruelty charges after driving to work and leaving the child in the car. Police say Harris told investigators he conducted a similar Internet search before the boy died.
