CNN -- New details were revealed in the Georgia hearing against Justin Ross Harris, the father accused of murder after leaving his toddler son in a hot car for seven hours.
What was Harris allegedly doing while his 22-month-old son, Cooper, suffered in the back of his scorching SUV?
Evidence shows that he was having up to six different sexting conversations - including one with a 16-year-old girl.
There were stunning claims of raunchy text messages, suspicious internet searches, and a plan to kill his son.
The video shows clips of the claims being made in court, the reaction from Harris and his wife, and testimony from Cobb County police and Harris' brother.
The detective testifying gave details about what Harris was doing online within two weeks prior to his son's death.
He also said the couple had financial problems, and a $25,000 life insurance policy on their son.
Autopsy reports also revealed that the child had scratches on his face and abrasions on the back of the head from injuries sustained before death.
The defense is still maintaining that it was a "tragedy and an accident".
