Incredible new details are emerging about what brought rescuers to a toddler trapped in a car in a frigid river.
18-month-old Lily Groesbeck was found alive in an overturned car after a crash in which the vehicle plunged into a frigid river in Spanish Fork, Utah.
It was not until 14 hours after the crash that a fisherman stumbled upon the car and alerted emergency personnel.
Ainsley Earhardt reported on "Fox and Friends" that as rescuers rushed down to the car, four police officers all say they heard the same thing: a woman calling out, begging for help.
But they can't explain who that voice was, because the baby's mother, 25-year-old Lynn Groesbeck, was killed in the crash hours before, and the voice they heard was too mature to be the toddler. 
"When we all talked together, I said, 'Was I the only one that was hearing this?' thinking that I was hearing things," Tyler Beddoes, one of the officers who rescued the toddler, explained. "And when I talked to the other officers, we all had heard the same thing, a voice saying, 'Help us. Help me.'"
Another officer described the same thing to Deseret News.
"We've gotten together and just talk about it and all four of us can swear that we heard somebody inside the car saying, 'Help,'" said Officer Jared Warner.
The officers say that the calls for help pushed them to work even harder to flip the car over.
When they righted the partially submerged vehicle, they were shocked to find the mother dead and the toddler alive.
