BRUNSWICK, Ga. -- A former escort took the stand Friday in the trial of the father accused in the hot car death of his young son.

Ross Harris is facing several charges, including malice murder and felony murder, in the death of his son, Cooper. The 22-month-old was found dead in the back of an SUV back in June 2014. Harris claims it was a tragic accident.

Daniela Doerr testified that she had sex with Harris three times in May 2014 -- the month before Cooper's death. She said that Harris didn't seem to take care of his appearance.

"He didn't have any presence about himself," she said. "He doesn't care. Very dumpy, a little bit overweight, a little bit on the hefty side. He just didn't care about his appearance, you can just tell."

Under questioning by defense attorney Maddox Kilgore, Doerr said that she got out of the escort business after she became pregnant.

Prosecutors have stated that Harris was sending explicit messages to several women in the months before Cooper’s death, and that he was sending sexually explicit texts to other women on the day of the hot car death.
