Police noted that Dunn took her to the hospital because the initial 911 call wasn't medical-related. In the audio from police footage, Dunn can be heard saying, "It's OK, baby".
"It's OK, baby; talk to me".
"I didn't feel a pulse", Dunn said.
"Once the cold air hit her, that's when I started noticing her eyes kind of fluttering", Dunn recalled.
At 4:23 into the video, he gets out of his cruiser and approaches the vehicle in which the girl had been for hours, according to the Sheriff's Office. As a father himself, Dunn feared the worst. With his heart still racing, he finally slumped over beside his patrol auto. "And then when it finally goes away, how it really does affect the body", he said.
Dunn said, "Sometimes we are able to have a moment like this that makes it all worthwhile".

Officials said the girl was left in the auto when her mother, 33-year-old Casey Dyan Keller, drove to a liquor store with three children, returned home but left the 3-year-old in the vehicle.
The police reported that the girl spent the night and the first half of the day in the auto, in total she stayed there for 12 hours. The toddler girl was reportedly slipping in and out of consciousness and the vehicle windows were rolled up.
The girl was released from the hospital three days after the incident and Dunn was able to meet her.
Keller was arrested and charged with child neglect with great bodily harm and is held in the John E Polk Correctional Facility on $15,000 bail.
The kid was taken to the hospital immediately after when Deputy Dunn put on his sirens and rushed her to get help. Shortly afterward, her father reached out to Dunn and arranged a meeting so Dunn could reunite with the toddler.
"She's a fighter", he said.
