"She come (sic) to pick up her child, and I informed her that I did not have her child. And she realized that she had left it in the car," she said to the dispatcher.
Gray told police she made several stops on the morning of August 7, 2012, to drop off her three other children. She was certain she dropped off Joel, too, at the daycare.
When Gray was told Joel was not at the daycare facility that afternoon, she rushed out to the parking lot to find him strapped in his car seat in the backseat of her minivan.
After several hours in the enclosed vehicle, with temperatures near 93 degrees, daycare workers immediately started CPR, but Joel did not respond.
Dispatcher: Is he awake?
Caller: No, ma'am.
Dispatcher: Is he breathing?
Caller: He's not breathing.
Joel was pronounced dead a short time later by medical personnel.
Officers on the scene that day said Gray was "distraught." She was taken to the hospital as a precaution.
Following her guilty plea last month, Gray was sentenced to 11 months and 29 days of supervised probation for each charge and 200 hours of community service. If she completes the conditions of her plea, the charges against her can be dismissed.
