Investigators in Southeastern Wisconsin say they have new clues into the death of a newborn.

The Dodge County Sheriff says a metallic-blue Dodge Shadow was seen around the town of Theresa; it's the same area where a baby, believed to be less than a day old, was found in a garbage bag in the woods.

Deputies are now asking everyone in the county to be on alert for the never before seen vehicle, and for anyone to come forward with information about the mother.

Baby Theresa, as the child has been named, will be laid to rest on Monday afternoon.

Residents have donated clothing, a burial plot and grave marker.
