COBB COUNTY, Georgia - Parents have accidentally left their children to die in hot vehicles, but that isn't necessarily what happened in the June 18 death of 22-month-old Cooper Harris, investigators in Georgia said late Wednesday afternoon. Harris is an Alabama native and University of Alabama graduate who worked as a police dispatcher for the Tuscaloosa Police Department for three years. 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.

 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. A petition signer identified as William Overstreet wrote that he couldn't imagine that man he says he knows intentionally killed his child. 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. 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. Here's what we do know: 
 
 JUST WATCHED What can dad's Google searches tell us?
– 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.
