Colorado Springs, Colo. (AP) A four-year-old boy found face down in a sandbox at a Calhan day care died of suffocation.
The El Paso County Coroner's office released autopsy results Monday in the death of Carl Anderson.
The boy died Thursday after a child care worker discovered him face down in a sandbox at Calhan Children's Center.
Calhan Police Sergeant Steve Hannum says Carl put his head in a 12- to 16-inch hole that another boy had dug. Carl was partially buried when the sand around him collapsed.
Police say the boy was under the sand for approximately one minute. He was pronounced dead at memorial hospital in Colorado Springs about an hour later.
Calhan police and the State Department of Humans Services are investigating.
