Police in Sioux Falls are investigating the death of a 2-month-old boy who was found unresponsive at an in-home daycare.

The baby was found unresponsive in a car seat last Friday.

The infant died later at a hospital.

There were no obvious signs of trauma.

Results of an autopsy are pending.

No charges have been filed, though police say the daycare was in violation of several city policies, and it has been shut down until the investigation is complete.
