Illinois authorities released the emergency phone call made after a 6-year-old boy was consumed by a sand dune at Indiana Dunes National Lakeshore park along Lake Michigan.
"My friend's son, he got stuck in a sand dune, and he's like under the sand and they can't get him out," the caller said. "My husband and his dad are trying to dig him out."
A spokesman for the University of Chicago Medicine Comer Children's Hospital says Tuesday that Nathan Woessner's condition remains unchanged.
The Sterling boy was buried for more than three hours before rescuers pulled him from 11 feet of sand on Friday. He was limp and cold, but began breathing on his way to the hospital.
Doctors say he's expected to recover and should be released in about two weeks.
Dr. Tracy Koogler, the medical director of pediatric intensive care at the University of Chicago Medical Center, told TheIndyChannel.com that he may suffer some lung problems in the future buy he can move his limbs.
"Because of his lung injury, we are trying to keep him sedated with medication, and intermittently we have also had to give him medication to paralyze him," Koogler said. "We actually don't want him awake and following commands and so forth."
The Mount Baldy area at the Indiana Dunes National Lakeshore will remain closed indefinitely after the accident.
Authorities believe Woessner may have fallen into a hole that was created by a long-buried tree that had decomposed, leaving a void in the sand.
