CHIPLEY, FL - For those in law enforcement, a missing child case rarely ends well.

So when a missing 7-month-old Chipley girl was actually found alive, it was an emotional moment for first responders.

We talked to the FDLE investigator who found Baby Shannon on Wednesday night in a story you will only see on Three.

Hayley Hall usually works crime scenes after someone is killed.

So she and her fellow investigators were expecting the worst when they walked into Susan Baker's trailer to execute a search warrant.

After turning over the entire house for two hours, they entered the only bedroom that hadn't been cleared.

They looked under the bed, and saw the wooden chest which held Baby Shannon inside.

"We opened the box, she was very still for the first few seconds, and i couldn't see her face, just saw her torso, and she was very still, my heart sank, but then I saw her arms move, she was alive."

Hill says that's when Baby Shannon looked around and smiled at investigators.

It was a happy ending but still an emotional shock for Hill, who actually cried from the relief of finding the child alive.
