The eyes of the nation are now on Leanna Harris, the mother of the 22-month-old toddler who died in a hot car, with speculation growing that she too may face charges.
Headline News anchor Nancy Grace told INSIDE EDITION, "There is no doubt in my mind that law enforcement is looking at the wife, Cooper's mother, Leanna Taylor Harris."
Her husband, Ross is accused of deliberately leaving their son, Cooper in the car.
Sitting in the courtroom at her husband's probable cause hearing last week, Harris stared blanky ahead as prosecutors detailed how he was sexting up to six women as the 22-month-old toddler struggled to survive in the sweltering SUV.
Nancy Grace says her behavior since her son's death is raising serious questions. Grace told INSIDE EDITION, "She sat there looking bored and snapping gum on the front row. I watched her."
Police say when Leanna Harris went to pick her son, Cooper up from day care, she was told he'd never been dropped off. And then, seemingly out of the blue, a police officer stated in court, "In front of several witnesses, all of a sudden she states, 'Ross must have left him in the car.' "
Grace said, "Unless she's clairvoyant, how did she know that?"
Police say she was also strangely calm when given the horrifying news that her son had died.
The prosecutor asked, "After being told that he was deceased, did she ask to see her son or anything like that?"
A police officer replied, "No."
"Who did she ask to see?" asked the prosecutor.
"She asked to see her husband," said the officer.
Police also noted her calm demeanor as they overheard Leanna's mother asking her about Cooper's death. A police officer stated in court, "During this, she's like, 'Why aren't you crying? Why aren't you reacting to this?'"
"And what did Leanna say?" asked the prosecutor.
"She said, 'I must be in shock,'" replied the officer.
And then, when she was left alone with her husband, Ross, at police headquarters after he was charged with murder, the officer described, "She had him sit down and he starts going through this and she looks at him and says, 'Did you say too much?'"
Leanna Harris has not been named as a suspect nor charged with any crime. Ross Harris has pled not guilty and claims the tragedy was an accident.
