ATLANTA -- The father of a Georgia toddler who died in a hot SUV told authorities that he did an online search about children dying in vehicles because he was afraid it could happen.<br />

Justin Ross Harris faces charges of murder and second-degree child cruelty in 22-month-old Cooper Harris' death.<br />
<br />
Search warrants released Saturday by Cobb County Police Department say Harris told police that he researched what temperature can cause a child's death in a car.<br />
<br />
The warrants say police were looking for a laptop, electronic devices and evidence of child neglect or abuse at the family's Marietta home. Harris' phone and car were included.<br />

Harris has told police he was supposed to drive his son to daycare but drove to work on June 18, forgetting the boy was in the car.
