Jury deliberations have resumed for a third day in the murder trial of a Georgia man whose toddler son died after being left for hours in a hot car.

Jurors returned to a county courthouse in the coastal city of Brunswick on Thursday morning to continue weighing the case against Justin Ross Harris. The Atlanta-area web developer moved to Georgia from Alabama in 2012. He was charged with murder after his 22-month-old son, Cooper, died in June 2014.

Harris told police he forgot to take the boy to day care and unknowingly left the child in the back of his SUV outside his workplace. But prosecutors say Harris intentionally killed his son to escape his family responsibilities at a time he was pursuing sexual affairs outside his marriage.

The jury has been deliberating since Tuesday.
