An 18-month-old girl placed in foster care in Scott County has died.

"At this time this is an on-going, active investigation," said Sheriff Luke Hennen.

"Our investigators are working hard to obtain answers regarding the circumstances surrounding this incident."

Emergency dispatch was contacted Sunday afternoon about a child having difficulty breathing at a home in the 4000 block of Morlock Drive in Sand Creek Township, according to the Sheriff's Office.

Emergency responders found the girl unresponsive. She was taken by air ambulance to Children's Hospital in Minneapolis. The hospital notified the Sheriff's Office on Tuesday that the girl had died.

The child had been placed in foster care at that address through Hennepin County, the Scott County Sheriff's Office said.

Autopsy results are pending.
