-----

1:39 p.m. Floyd says she and Harris began chatting at 5:49 a.m. the morning of his son's death. They chatted until 2:10 p.m. that day. Floyd says he asked her for an inappropriate photo of herself that day and she sent him one.

-----

11:26 a.m. Brani says he is not a forensic pathologist so he can't describe the exact impact a child's body would have on the internal temperature of the car, but he believes his readings are accurate and wouldn't be changed significantly.

-----

11:18 a.m. Brani says he accessed the vehicle briefly around the same time Harris did on the day of Cooper's death to keep results accurate.

-----

11:13 a.m. Court resumes from break. Brani's testimony continues.

-----

10:33 a.m. Court recesses for morning break.

-----

10:24 a.m. Defense argues that the temperatures are not accurate because there was no child in the car. Brani says he disagrees and believes the information is accurate.

-----

10:16 a.m. Brani says any variables or discrepancies discovered in the morning would not "have any meaningful effect on the temperatures, especially in the afternoon."

-----

9:57 a.m. Defense says there's no way to know if the starting temperature in the heat test was the same as the actual starting temperature on June 18, 2014. Brani says he began his test an hour earlier than Harris actually parked his car so possible discrepancies in A/C temperature should even out.

-----

9:50 a.m. Defense argues that Cooper's body would have added heat to the car. Brani says it's true that if there is an object that is hotter than the internal temperature of the car it would act as a heat source. "In theory, the temperature may be a little warmer where that body was."

-----

9:45 a.m. Brani says his testing in this case cost taxpayers around $24,000.

-----

9:40 a.m. Brani says he had not completed hot car testing like this before so he did lots of background research before and after completing the testing.

-----

9:26 a.m. Brani says around 3:30 p.m., the temperature reached 125 degrees.

-----

9:19 a.m. Brani says the temperatures inside and outside the car matched up around 11:35 a.m. at 88 degrees. At around 12:45, about the time Harris returned to his car after lunch, Brani says the temperature at the car seat was 98 degrees. He says the temperature in the car rose above 100 degrees shortly before 1 p.m.

-----

9:18 a.m. Brani says when testing began, the temperature inside the car was 65 degrees and outside was 80 degrees because the air conditioning had been running.

-----

9:10 a.m. Brani says on June 18, 2014, the day of Cooper's death, the temperature was 91 degrees. On July 8, the day they did the heat study, it was 92 degrees.

-----

9:00 a.m. Brani says he took temperature readings every hour throughout the day.

-----

8:58 a.m. Brani says he completed the heat testing in Harris' car at the Home Depot tree house office on July 8, 2014, three weeks after Cooper's death.
