Leanna Harris’ husband, prosecutors alleged Thursday, had two sides: Churchgoing family man and another, darker persona, one that compelled Ross Harris to knowingly leave their 22-month-old son to die, locked inside a sweltering SUV. 
 
 Based on her own, sometimes confounding words, along with evidence disclosed at her spouse’s probable cause hearing Thursday, many are wondering whether there’s another side to Leanna Harris.

 The 30-year-old dietitian, who two years ago moved to Georgia from Tuscaloosa, Ala., has not been charged with any crime. But police have disclosed that, like her husband, she had researched children dying in hot vehicles prior to her son Cooper’s death, telling officers it was her “worst fear.” On average, 38 kids die each year after being trapped inside automobiles, according to KidsAndCars.org. 
 
 Investigators described her behavior the day of her son Cooper’s death as odd, if not suspicious. 
 
 When informed by workers at her son’s day care facility that Cooper had never been dropped off, she calmly responded, “Ross must have left him in the car. There’s no other explanation,” according to Cobb County Police Det. Phil Stoddard’s testimony Thursday. 
 
 Then, when reunited with her husband at police headquarters after he had been charged with murder, Leanna Harris asked him, “Did you say too much?” according to Stoddard. 
 
 “There isn’t enough to make her a co-conspirator … yet,” said criminal defense lawyer Esther Panitch.

 Kelly J. Huff / Pool / Marietta Daily Journal / AP Leanna Harris, wife of Justin Ross Harris, the father of a toddler who died after police say he was left in a hot car for about seven hours, looks on during her husband's bond hearing in Cobb County Magistrate Court on July 3, 2014, in Marietta, Ga. Harris, who police say intentionally killed his toddler son by leaving the boy inside a hot SUV, was exchanging nude photos with women the day his son died and had looked at websites that advocated against having children, a detective testified Thursday. At that same hearing, a judge refused to grant bond for Harris, meaning he will remain in jail. 
 
 Whatever Leanna Harris’ role winds up being in this case — witness, defendant or supportive wife — prosecutors and the public are taking note of her public actions. What they’ve seen so far is stoicism that seems at odds with what has become a public tragedy. 
 
 She has expressed little emotion throughout. At Thursday’s hearing, she stared blankly ahead, chewing gum as prosecutors delivered one bombshell after another. 
 
 When she called home June 18 with the grim news of Cooper’s death, her mother could be overheard on the phone: “Why aren’t you crying? Why aren’t you reacting?”

 Her response, according to Stoddard: “I must be in shock.” 
 
 Then there was her eulogy at Cooper’s funeral last Saturday in Tuscaloosa. To those who don’t know her, Leanna Harris’ comment that she wouldn’t bring her son back, even if she could, seemed suspicious.

 “He’s in the most peaceful, wonderful place there is,” Leanna Harris said. 
 
 But the 250 or so mourners who gathered at University Church of Christ gave her two rounds of applause, and Harris’ statement is not unusual among the deeply religious who believe the afterlife is God’s greatest gift. 
 
 Still, it’s clear, according to veteran legal observers, that police are looking at Leanna Harris’ potential culpability in her son’s death. On Thursday, Cobb County District Attorney Vic Reynolds said the investigation continues and “much work remains,” though he offered no details on where the probe may be headed. 
 
 “Knowledge of a crime isn’t prosecutable. A cover-up is,” Panitch said. 
 
 But if, as many increasingly believe, her husband ends up facing more significant murder charges, prosecutors may seek to use Leanna Harris as a witness. In Georgia, the spousal privilege shielding a wife from testifying against her husband, and vice-versa, doesn’t apply in cases of domestic violence or death of a child.

 “She needs to make a deal before the state finds more evidence against her,” Panitch said. 
 
 So far, Leanna Harris has remained loyal to her husband of seven years. At Cooper’s funeral, she said she holds no anger toward her husband. 
 
 “Ross is and was a wonderful father,” she said. As Ross Harris listened from jail on speaker phone, his wife told him, “I love you and I’m doing this for you.” 
 
 It’s unclear whether Leanna Harris knew then of her spouse’s “sexting” habits, first disclosed publicly during Thursday’s hearing. Friends and family shielded her from reporters as she left the courtroom and insist she’s a woman of strong faith who treasured her role as wife and mother. Ross Harris’ half-brother, Randy Michael Baygents, a police officer for nearly two decades, said Thursday had Ross Harris been released on bond he would have returned home. 
 
 “What you saw here is what is truly in her,” the Harris’ pastor, David Eldridge, said at Cooper’s funeral. “There is an example here for all of us on how to deal with things.”

 Her eulogy was part memorial, part confessional. 
 
 “Some of you might wonder how I’m standing here today and I ask myself the same question,” Leanna Harris said. “I should be crumpled into a pile of tears and snot on the ground. (The Lord) is standing behind me, holding me up.” 
 
 She spoke of her difficulties getting pregnant and her awkward teen years. 
 
 “Junior high and senior high — they weren’t the happiest times (for me),” she said, listing heartbreaks her son would be spared. “He won’t have to suffer through the death of his (grandparents). He won’t have to suffer through the death of me and Ross.” 
 
 In his closing prayer, Eldridge said, “I’m not sure there’s a better testimony to who You are or what You do than Leanna.”

 Troublesome details continue to emerge from the June 18 death of 22-month-old Cooper Harris, who died from hyperthermia after his father, Justin Ross Harris, left him locked in his car seat on a sweltering day when temperatures pushed toward 90 degrees. 
 
 Cobb Police Det. Phillip Stoddard testified at a bond hearing that Cooper had scratch marks on his face and abrasions on the back of his head, most likely indications the little boy was desperately trying to get out of his car seat. 
 
 Other information disclosed at Thursday’s court hearing included that Harris, 33, sent six sexually explicit emails, including a photo of his genitals, to women and a teenage girl, according to the Marietta Daily Journal. 
 
 Stoddard also testified the boy’s mother acted strangely calm on the day of her son’s death. 
 
 Her husband has claimed he accidentally left his son in the car after forgetting to drop him off at daycare. 
 
 When Leanna Harris arrived at the Little Apron daycare center, she was told her son never arrived, Stoddard testified. 
 
 His mother then said her husband must have left him in the car. 
 
 After being questioned at police headquarters, the couple were briefly reunited, the detective said. 
 
 “Did you say too much?” Leanna Harris asked her husband, according to Stoddard. 
 
 The father told investigators he had taken his boy to breakfast at a fast-food restaurant, then drove to work forgetting Cooper was in the car.

 The drive was less than a mile and took 30 to 40 seconds, Stoddard told the court. 
 
 After sexting at his Home Depot job, Harris went to lunch with his co-workers, bought some light bulbs, and went to his car, opened the driver’s door and threw them in, authorities said. 
 
 Harris claims he didn’t see his child. 
 
 Stoddard testified that the belts on Cooper’s car seat were set at the tightest possible setting and that the car seat was facing toward the rear, a position usually used only for infants. 
 
 Cooper’s head was plainly visible above the seat, Stoddard said.

– Leanna Harris—unlike her husband—has not been charged in the death of her 22-month-old son in a hot car but investigators are puzzled by some of her behavior. Police say she had done online research on children dying in hot cars and on the day her son, Cooper, died, she calmly said, "Ross must have left him in the car. There's no other explanation," after being told he had never arrived at day care, the Atlanta Journal-Constitution finds. When she was briefly reunited with her husband at the police station, police say she asked him "Did you say too much?" Some of her remarks at her son's funeral also raised eyebrows. As her husband listened in from jail, she said she wouldn't bring Cooper back even if she could. "He's in the most peaceful, wonderful place there is," she said. The 30-year-old has shown little emotion at court hearings and legal experts aren't sure whether she will end up being charged as a co-conspirator or used as a witness against her husband, which Georgia law permits in cases involving the death of a child. In other developments: Horrifying details of the boy's death emerged at a bond hearing a few days ago, reports the New York Daily News. A police officer testified that the little boy had desperately struggled to free himself from the car seat inside the hot SUV. Scratch marks on the boy's face and abrasions on the back of his head are signs of a frantic effort to get out of the seat. Search warrants released the next day stated that the belts were at the tightest setting. At the same hearing, it emerged that Justin Ross Harris had exchanged explicit messages and photos with six women as his son baked to death. Investigators say Harris appeared to be trying to cover his tracks on all three computers he used, and they have only "scratched the surface" in their search for deleted files. "People think 'Well, this is a cell phone. Once I delete a picture or text message or my contacts, it's gone,'" a computer forensics expert tells NBC 11. "No. Even when you hit 'reset' on your phone, that information is still stored on that hard drive."
