The high that day was 101, according to National Weather Service records.

Oct. 24 -- A final autopsy of the Bates' brothers reveals that River suffered core body temperatures of at least 109 degrees before his death.

Nov. 19 -- Trial date set for Aug. 27.
A jury has been selected in the trial of a Bradley County mother accused of murder in the overheating death of her two young sons.
Tasha Bates, 27, is facing murder, child abuse and drug charges in the deaths last summer of 3-year-old River and 5-year old Leland Bates, who died of hyperthermia in what prosecutors say was an overheated car.
Previously Bates has claimed that she left the boys alone outside on a Slip n Slide for 45 minutes.
The 16-member jury — which includes two sets of alternates in this case — is composed of five women and eleven men.
Before settling on the jury prosecutor Stephen Hatchett and Bates' public attorney Richard Hughes quizzed the jury, asking them if they could be fair despite the sensitivities of a case that involved children.
Hughes began by saying "there is not anything more tragic or sad or shocking than the death of young children."
But later on he asked whether jurors could keep an open mind.
"This is case is not about how you would raise your children. It's not about your lifestyle. …Your obligation as a juror is to decide the case based on the facts that are presented."
A number of potential jurors said they simply could not be fair given the fact that children were involved, and were dismissed.
The two attorneys also questioned potential jurors about how much media exposure they've had to the case.
"I'm going to do my dead-level best to convict this woman of ever charge against her, but she deserves a fair trial," Hatchett said before asking potential jurors about their connection to the case.
While no proof has been entered, both attorneys references some details of upcoming testimony, including evidence involving Bates' alleged drug usage and the fact that the boys' slept in a garage beside their trailer because there was no air conditioning at their home.
