Cobb police spokesman Michael Bowman said the department turned over Ross Harris’ SUV and Cooper’s car seat to investigators with the district attorney’s office who conducted the “heat test.”
Meanwhile, a local TV station is reporting that toxicology reports from the autopsy performed on the 22-month-old showed no sedative was present in his system, dispelling a well-recycled theory that Ross Harris may have drugged his son on June 18 before leaving him in his 2011 Hyundai Tuscon for more than seven hours. Neither Cobb police or a spokeswoman for the D.A. would confirm the report.
Harris, 33, contends he forgot his son was inside the vehicle. But police, who have charged him with felony murder and cruelty to children, say they believe he intended to kill Cooper.
