A mystery arose from the rescue: The three police officers who entered the water all say they heard a voice calling for help.

The mother was dead, but the officers told CNN affiliate KSL that they heard an adult’s voice calling to them.

“It felt like I could hear someone telling me, ‘I need help,'” DeWitt told KSL. “It was very surreal, something that I felt like I could hear.”

Warner said he heard the same.

“(It) wasn’t just in our heads,” he told KSL. “To me, it was plain as day. I remember hearing a voice that didn’t sound like a child, just saying ‘help me.'”

Tyler Beddoes, the third officer at the scene, said the same.

“Someone said ‘help me’ inside that car,” he said.
