On March 7th, 2015, a fisherman spotted an overturned vehicle in a Spanish Fork, UT river. The car was partially submerged, but when officers approached they heard a desperate voice pleading for help.

“The four of us can swear that we heard somebody inside the car saying, ‘Help,'” officer Jared Warner told KSL TV. “We were down on the car and a distinct voice says, ‘Help me, help me.’ It wasn’t just something that was just in our heads. To me it was plain as day.”

However, when officers searched the wreckage they found only 18-month-old Lily, unconscious, and her deceased mother, Jenny Groesbeck, 25. Rescuers believe Jenny died in the crash, leaving Lily trapped for up to 14 hours. The baby is currently recovering at a local hospital.

So who, or what, called for help?

“I don’t know what I thought I heard,” officer Tyler Beddoes said. “I’m not a typically religious guy. It’s hard to explain — it was definitely something. Where and why it came from, I’m not sure.”

The Spanish Fork incident isn’t the only time mysterious circumstances led police to discover an injured child. In 1994, a traveler near Placerville, CA spotted a nude woman laying on the side of the road. An officer responded to the call but found no trace of the naked woman. The officer returned the next day and eventually discovered a demolished car at the bottom of a 40-foot embankment. Inside was Nick Skubish, 3, and his deceased mother Christene. Police never did determine who, or what, the traveler saw that night, but many people believe it was Christene’s ghost trying to save her son.
