Ross Harris trial: Nov 3

The defense called an expert witness to the stand in Ross Harris murder trial on Thursday. Harris, 35, is a Cobb County man charged with murder in the June 2014 death of his 22-month-old son, Cooper, who was found dead in the back seat of Harris' hot SUV. Prosecutors believe he intentionally left his son to die at a time when Harris was unhappy in his marriage and looking for relationships with other women. Defense attorneys said the death was a tragic accident. In April, the trial was moved from Cobb County to Glynn County.

Here are of the key developments which happened during the day:
