Story highlights Little has emerged about father of 22-month-old boy who died in car 
 
 But people who say they knew him praise him as a good man 
 
 He's charged with murder in the June 18 death of Cooper Harris 
 
 Prosecutors say he may be a criminal. People who say they know him describe him as a great dad. 
 
 So what's the story with Justin Ross Harris, the Cobb County, Georgia, man accused of murder after leaving his toddler strapped into his car seat under a blistering Southern sun? 
 
 The truth is, we don't know much. Police and prosecutors are being tight-lipped about the case against Harris, who is charged with felony murder and second-degree child cruelty in the death of 22-month-old Cooper Harris. He's refusing visitors to the Cobb County jail -- including CNN. His family isn't talking, and his attorney has not returned repeated telephone calls from CNN. 
 
 Here's what we do know:

 Harris is 33 years old. He has worked at Home Depot for two years. Home Depot Corporate Communications Manager Catherine H. Woodling said he worked "on our .com business, but I'm not sure what his title is." 
 
 He was placed on unpaid leave after the charges were filed in the June 18 incident -- a routine action in such situations, Woodling said. 
 
 He held jobs at the University of Alabama from August 2001 until May 2006 as a parking monitor and later as a mail delivery clerk, said Cathy Andreen, university director of media relations. 
 
 He worked as a police dispatcher in Tuscaloosa, Alabama, from June 10, 2006, to May 22, 2009, according to Police Department spokesman Sgt. Brent Blankley. He said the department would confirm only Harris' tenure, and not any details from his work history, so we don't know why he left the job. 
 
 In May 2012, Harris graduated from the University of Alabama with a bachelor's degree in commerce and business administration, having majored in management information systems, Andreen said. 
 
 The boy's mother, Leanna Harris, is listed as having the same home address as the father, but she told CNN last week that she's been advised not to discuss the case with the media. They were married May 7, 2006, in Tuscaloosa, according to the Tuscaloosa County marriage license clerk. 
 
 A woman who knew Harris as a teenager but hasn't seen him in 15 years described him as "a good kid" who spent a lot of time at University Church of Christ in Tuscaloosa, where Cooper is to be remembered at a funeral Saturday. 
 
 "We were always happy to have him in our home. And we were happy that he was friends with our child," Carol Brown told CNN's Nick Valencia. 
 
 People who say they know Harris posted change.org petitions asking that the charges against him be dropped but closed the petitions this week. One of the organizers posted, "based on the recent developments this petition is no longer revelant." 
 
 CNN couldn't immediately confirm the authenticity of the petition comments, many of which speak glowingly of Harris as a man and a father. 
 
 One petition signer, identified as Matt Wiley of Northpoint, Alabama, described Harris as "a great husband and a great father." 
 
 Another, identified as Michael Gordon of Northpoint, wrote of what he said was Harris' "grace and exemplary attitude." 
 
 "He has been nothing but a caring father and supporting husband. He worked full time and went to school for many years to get where he wanted to be," he said. 
 
 A petition signer identified as William Overstreet wrote that he couldn't imagine that man he says he knows intentionally killed his child. 
 
 "I've known Ross for over 10 years and he is a selfless man who loved people and loved his family more," the post reads. "NOTHING in his life even hints at this behavior." ||||| MARIETTA, Ga. (AP) — A Georgia man who police say intentionally killed his toddler son by leaving the boy inside a hot SUV was unhappy in his marriage and had looked at websites that advocated against having children, a detective testified Thursday.

 Cobb County Police Detective Phil Stoddard testified at a hearing that evidence showed Justin Ross Harris was practically leading a double life and should not be granted bond. Stoddard described the evidence police have suggesting Harris, who is charged with murder, killed his 22-month-old son Cooper intentionally. 
 
 Harris has told police he was supposed to drive his son to day care the morning of June 18 but drove to work without realizing that his son was strapped into a car seat in the back. 
 
 Harris was exchanging nude photos with several women, including teenagers, even on the day his son died when he was at work, Stoddard said. The man also had looked at a website that advocated against having children and had done an Internet search for "how to survive in prison," the detective said. 
 
 "I think the evidence now is showing intent," Stoddard said. He said Harris should remain in jail because he is a flight risk: There is evidence he was leading a double life, he has family in Alabama, and the former 911 dispatcher has law enforcement experience. 
 
 Harris is a native of Tuscaloosa, Alabama, and moved to Georgia in 2012 to work for Home Depot. 
 
 The detective said after the boy died, Harris showed no emotion while being interviewed by investigators. At one point after Harris pulled over with the dead child in a strip mall parking lot, an officer told Harris to get off his cellphone, Stoddard said. Harris twice refused, using profanity, and was then arrested. 
 
 Scores of reporters and some curious members of the public were at the hearing just outside Atlanta, where police and prosecutors laid out the most detailed account yet of their case against Harris. Some of Harris' supporters also were in the courtroom. ||||| (CNN) Leanna Harris, the mother of a Georgia toddler who died locked in a hot car, has told authorities that she researched such deaths and how they occur, according to a police affidavit. 
 
 Her husband, Justin Ross Harris , the child's father, who is in jail without bond, has also told police that he used the Internet to research child deaths in vehicles and what temperature it needs to be for death to occur, police said. 
 
 "Justin stated that he was fearful that this could happen," the police affidavit said. 
 
 In the document released Sunday, police say that during questioning Leanna Harris "made similar statements regarding researching in car deaths and how it occurs." 
 
 The time frame for when this alleged research took place remains unclear.

 Their son, Cooper Harris, who was 22 months old when he died June 18, was buried after a funeral Saturday in Tuscaloosa, Alabama. 
 
 Leanna Harris emphatically told a crowd at her son's funeral she loves and stands by her husband, even though he is charged with murder in the child's death. 
 
 "Am I angry with Ross?" Leanna Harris said Saturday. "Absolutely not. It has never crossed my mind. Ross is and was and will be, if we have more children, a wonderful father. Ross is a wonderful daddy and leader for our household. Cooper meant the world to him." 
 
 Police said Justin Ross Harris told them he forgot to drop his 22-month-old son at the day care center before going to work. The boy died after spending seven hours in a child safety seat in the back of an SUV. 
 
 Harris was arrested hours after his son's death and has pleaded not guilty to charges of murder and second-degree child cruelty. 
 
 The affidavit was filed in the application for a search warrant used to seize computers from the Harris home. 
 
 A timeline of events 
 
 On the day Cooper died, his father stopped for breakfast at a fast-food restaurant and afterward strapped his son into a rear-facing child restraint seat on his SUV's back seat, police said. 
 
 He drove to his workplace, a Home Depot corporate office, about a half-mile away. He works as a Web designer there. 
 
 Usually, he would take his son to an on-site day care. But that day, police said, Harris left him in the car seat. 
 
 During his lunch break, he returned to his car, opening the driver's side door to put something inside, police said. 
 
 After work, around 4:16 p.m., the 33-year-old father got in his car and drove away. A few miles away, he stopped the car at a shopping center and called for help. 
 
 When it became clear Cooper was dead, Harris was so inconsolable police had to restrain him. 
 
 "What have I done?" he wailed as he tried to resuscitate the boy. 
 
 The Cobb County medical examiner's office found the child's cause of death "consistent with hyperthermia and the investigative information suggests the manner of death is homicide," according to a Cobb County Department of Public Safety statement issued last week. Temperatures hit 92 degrees Fahrenheit on the day of Cooper's death. 
 
 The medical examiner's office is waiting for toxicology test results before making an official ruling as to the cause and manner of the toddler's death. ||||| Breaking News Emails Get breaking news alerts and special reports. The news and stories that matter, delivered weekday mornings.

 The Georgia dad charged with murder for leaving his 22-month-old son in a hot car to die will not be allowed to attend the boy's funeral Saturday. Cobb County officials say jail policy dictates that Justin Ross Harris must be kept locked up without bond while the rest of his family gathers in Tuscaloosa, Alabama, to mourn Cooper. The tot died of hyperthermia in a parked SUV while his father was at work at The Home Depot. 
 
 After police announced that the evidence will show the boy's death was not "simple negligence," the anonymous sponsor of a Change.org petition that collected 11,000 signatures in support of Harris shut it down. "I think that based on the recent developments this petition is no longer relevant. I still pray that this was truly an accident," a note on the petition reads. An online fundraiser collected more than $22,000 for the family but donations dwindled as police insisted the felony murder charge is warranted.

 — Tracy Connor
– The funeral for 22-month-old Cooper Harris takes place today, and dad Justin Ross Harris won't be allowed to leave prison to attend, reports NBC News. The 33-year-old left his son in a hot car in a case that police in Georgia's Cobb County say wasn't "simple negligence." As more fishy circumstances about the case have surfaced, supporters of Harris have taken down a Change.org petition demanding that police drop murder charges. Authorities say they will lay out the evidence against Harris in more detail eventually, and new details are scarce in the meantime because his family isn't talking to the media and Harris himself is refusing visitors in jail, reports CNN. His employer, Home Depot, has placed him on unpaid leave as those who know him try to make sense of the murder charges. "I've known Ross for over 10 years and he is a selfless man who loved people and loved his family more," reads a typical post on that now-closed petition site. "NOTHING in his life even hints at this behavior." Prior to his job with the online side of Home Depot, Harris worked as a police dispatcher for three years in Tuscaloosa, Alabama, reports Al.com. He also had low-level jobs at his alma mater, the University of Alabama.
