Winston White was found dead inside the car after temperatures inside reached a massive 150 degrees. All windows and doors were locked.
Genee Brumfield, the boy's godmother, has been charged with negligent homicide after the toddler was found in the car in New Orleans. She had been babysitting the toddler when she stopped off to visit her mother, leaving Winston locked in.
Police spokesperson Marlon Defillo said they were investigating the incident:
'For some unknown reason, Brumfield decided to stop by her mother's home, leaving the three-year-old inside the car with the windows up and the doors locked.
'We are still fact-finding. We are still talking to neighbours, relatives, anyone who may have information as to what happened, trying to determine from residents if someone may have seen the child in the vehicle.'
