(WXIA, WGCL, FOX 5) Justin Ross Harris wasn't the only one who researched children dying in hot vehicles before his son died the same way—police say his wife, Leanna, researched the same subject. The mother of 22-month-old Cooper Harris "made similar statements regarding researching in car deaths and how it occurs," according to warrants obtained by the Atlanta Journal-Constitution. Unlike her husband, Leanna Harris has not been charged, although she was questioned in the hours after her son was found dead in the back of her husband's SUV. She says she loves her husband and is standing by him, reports CNN, which notes that the medical examiner is waiting on toxicology reports before ruling on the cause of the toddler's death.
