A Georgia father who was charged with murder after leaving his son strapped into his carseat for seven hours reportedly searched online to find out how long it would take an animal to die if it were trapped in a hot car, WREG in Memphis reports.

Justin Ross Harris initially told police that he forgot to drop his son off at daycare and only realized he had been sitting in the car all day when he went to drive home. But this information, provided to WREG reporter Randy Travis (real name!), obviously casts doubt on that story.

That said, it's not the only source of suspicion amongst Cobb County police. According to Sgt. Dana Pierce, Harris' story wasn't adding up from the jump:

"Within moments of the first responders getting to the scene and doing their job and questions began to be asked about the moments that led up to their arrival at the scene, some of those answers were not making sense to the first responders," Pierce of Cobb County Police said.

Harris has pled not guilty to felony murder and cruelty to children charges.
