He says if prosecution doesn't call Taylor to the stand, the defense will.

-----

10:34 a.m. "He never forgot that he had a son. That wasn't the issue. He just lost awareness that he was in the car," Kilgore said.

-----

10:23 a.m. Kilgore says Harris used to go to Chick-fil-A after dropping Cooper at day care in the mornings so he was used to driving straight through the intersection back to work. He says it was his habit, his pattern.

-----

10:06 a.m. Kilgore says they will play video showing that Harris never looked inside his car when dropping off a bag of light bulbs during his lunch break. Prosecution claimed Harris would have been able to see Cooper when he did that. Kilgore says defense was so suspicious from the beginning that they got a search warrant to see if any light bulbs were even out at Harris' home

-----

10:00 a.m. Kilgore reads through messages Harris sent on the app Whisper to women on the morning of Cooper's death. Monday, the prosecution themed its opening statement around one of Harris' messages that same morning saying, "I love my son and all but we all need escapes." Kilgore says if Harris planned to kill his son, he wouldn't have written it in a text message.

-----

9:54 a.m. Kilgore says first responders and bystanders did not report smelling a "stench of death" like the prosecution claimed there was inside the car. He says detective smelled what he wanted to smell.

Defense: EMS personnel & medical examiner did not mention odor. Only the lead detective reported smelling "stench of death" at the scene.-- Carl Willis (@CarlWillisWSB)

-----

9:51 a.m. Kilgore says Ross never went to "child free" pages and sections on the internet that advocate living a child free life, despite what detectives say. He says months before his son's death Harris did visit the child free section on Reddit but did not click on any articles relating to the topic.

-----

9:46 a.m. Kilgore says video made by veterinarian titled "How hot does it get in a parked car" was a trending video on Harris' Reddit. Harris did not search for it, just clicked on the trending video.

On Claims Harris searched hot car deaths: "He never searched these things. It was something that was made up by the Cobb Co. Police Dept."

-- Carl Willis (@CarlWillisWSB)

-----

9:44 a.m. Kilgore says Harris NEVER told police that he researched how long it takes someone to die inside a hot car and what temperature it needs to be. He says Harris never did that, yet detectives swore under oath over and over again that he did.

-----

9:37 a.m. Kilgore says the lead detective's testimony that Ross showed no emotion in the interview room is not true. "He wept bitterly and cried out to God. Cried out in disbelief." Shows emotional video of Ross Harris crying alone in the interview room before detectives entered the room.

Defense attorney Maddox Kilgore shows the jury video of Ross Harris weeping with his face down @ the police station.

-----

9:34 a.m. Harris wipes away tears as the defense shows dash cam video from the day of Cooper's death.

-----

9:32 a.m. Kilgore says Harris first noticed Cooper when he went to change lanes while driving to the movies. "He knew right then his child was dead." Kilgore says he pulled over immediately and pulled Cooper from the car.

-----

9:29 a.m. Kilgore says Harris and his wife were devastated by their son's death. He says part of the state's evidence rests on the fact that Harris and his wife "didn't at like they should have," but questions how they were "supposed" to act after their son's death.

Harris' Attorney: State says Harris guilty of killing son because he didn't "act right" but he was really a "pitiful, broken man."

-- Ross Cavitt | WSB-TV (@RossCavittWSB)

-----

9:24 a.m. Kilgore says Harris' friends and church group knew he was dealing with sexual sins and had asked for help and prayer. His wife was aware of some of the problems and they had been to marriage counseling. Defense claims there was no "double life" as prosecutors tried to insinuate.

-----

9:23 a.m. His sexting throughout the day was after he had forgotten Cooper. Kilgore says that fact will be very crucial during the course of this trial.

-----

9:20 a.m. "Ross' sex life, no matter how perverse and nasty and wrong that we think it is, it doesn't have a thing in the world to do with the fact that he left that little boy. They're completely unrelated. Got nothing to do with each other ... It isn't some kind of motive to murder the person he loved more than anyone in the world," Kilgore says.

Defense says Harris' sex life has nothing to do with the fact that he forgot his son in the SUV.

-- Ross Harris Trial (@RossHarrisTrial)

-----

9:17 a.m. He says Harris never tried to blame anyone; called it "the biggest mistake of my life." Kilgore says responsible isn't the same thing as criminal.
