NAMPA, Idaho (AP) — Police in southwest Idaho say FBI lab results have determined that the skeletal remains of an infant found under the porch of a vacant home are female.

Nampa police tell the Idaho Press Tribune that results from the lab received on Tuesday didn't match the infant's DNA to any in the system and no arrests have been made. Authorities found the remains at a vacant Nampa home on Aug. 15, 2015, that had multiple renters previously.

Police say the remains had been under the porch for about a year before being found during a construction project. Police say they are looking into who lived in the house.
