Dramatic video shows moment officer saves little girl trapped for 12 hours in hot car

Heart-stopping footage has surfaced showing the moments a police officer saved the life of a little girl who was left in a sweltering car for more than 12 hours.

The Florida officer said he thought the three-year-old girl was dead when he found her “sweaty and limp” and unresponsive strapped inside the vehicle on June 17 – in the heat of the US summer.

Body camera footage released just days ago showed the officer running to his cop car while holding the little girl in his arms.

“It’s OK, baby; talk to me. You’re OK,” Deputy Bill Dunn was heard saying.

The officer told Fox News he blasted the air-conditioning and the child began to respond.

• Kind gesture from police called to home with boy screaming ‘Tick Tock

• Man unknowingly carried $50m Powerball ticket in wallet for two days

“Once the cold air hit her, I started noticing her eyes fluttering.”

At the time of the rescue, the Seminole County Sheriff’s Office shared on social media that Deputy Dunn “pulled her out, put her under air conditioning in his cruiser, and rushed her to the hospital,” where she made a full recovery.

Little girl’s mother left her behind

The child was left unattended in her family’s vehicle overnight and found the next morning, about 12 hours later.

Investigators learned that the girl’s 33-year-old mother, Casey Dyan Kelle, went on a liquor store run the previous night with her three children and upon returning home took her two older children into the apartment, but left the three-year-old girl behind.

It wasn’t until the next morning at 11am that Keller realised the girl was not in the apartment, so she called 911 to report her missing.

Keller was arrested and charged with child neglect with great bodily harm.
