Brandi Hitt has the story. Reporter: Your child stuck in a hot car with no way of getting them out. A into mom did what most would reaching out to emergency dispatchers only to be told help was not on the way. It was a simple mistake that could have had devastating consequences. Hi, my infant son is locked in the car in a parking lot. Reporter: Shana had just finished shopping at this Tampa, Florida, drugstore when she strapped her 10-month-old jack in the backseat of her car and shut the door not realizing she left the keys in jack's idle hands. In those three seconds when I was moving the cart he hit the lock but. She immediately dials 911. It's so hot outside. Reporter: Worried but still keeping her cool. Can somebody come out and open the door? Reporter: Certain the dispatcher would be eager to help. She was wrong. They won't be able to try to gain access to the car unless the child is in some kind of distress. Reporter: You heard right. Despite temperatures nearing the triple digits the dispatcher telling her they wouldn't come to free him unless he was clearly in distress. The dispatcher made a mistake. This is not the way we do business. Reporter: That's what Shana starts to panic. That was the scariest part watching him change and get obviously much, much hotter. Reporter: Eight minces after her initial call an off-duty police officer notices the frantic mother and calls 911. She's a little distraught. Reporter: This time getting a different dispatcher and different response. She says she called 911 and they said they're not going to come out unless the baby is in distress. No, no the at all. Reporter: Time is running out. With temperatures soaring another shopper uses a wrench to break a window and rescue jack and it's just in the nick of time. Temperatures inside a car can quickly get into the triple digits soaring nearly 30 degrees in just 15 minutes. Every year an average of 38 children in this country die after being left in a hot car. Last year it was 44. This morning the Tampa police department says it's launching an investigation and as for Shana she says she's grateful for the man who let her use the phone and the police officer who was there but in the end it was somebody using a wrench. You go the to thank that guy, as well. Thanks, Brandi. Scary.
